Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Cadence and its subsidiaries after elimination of intercompany accounts and transactions. All consolidated subsidiaries are wholly owned by Cadence. Historically, Cadence’s fiscal years were 52- or 53-week periods ending on the Saturday closest to December 31. During fiscal 2022, Cadence’s Board of Directors approved a change in its fiscal year end from the Saturday closest to December 31 of each year to December 31 of each year. The fiscal year change became effective beginning with Cadence’s 2023 fiscal year, which began on January 1, 2023. Both fiscal year 2022 and 2021, which are included in this report for comparative purposes, represent 52-week periods. Cadence’s first three fiscal quarters end on March 31, June 30, and September 30. No transition report was required in connection with this change. Use of Estimates Preparation of the consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Recently Adopted Accounting Standards Cadence has not recently adopted any accounting standard updates that are material or potentially material to its consolidated financial statements. New Accounting Standards Not Yet Adopted Segment Reporting In November 2023. the Financial Accounting Standards Board (“FASB”), issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” intended to improve reportable segment disclosure requirements, primarily through enhanced annual and interim disclosures about significant segment expenses. This standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. Cadence is currently evaluating the impact of this standard on its financial statement disclosures. Income Taxes In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. This standard is effective for fiscal years beginning after December 15, 2024, and may be applied on a retrospective or prospective basis. Cadence is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures. Foreign Operations Cadence transacts business in various foreign currencies. The United States dollar is the functional currency of Cadence’s consolidated entities operating in the United States and certain of its consolidated subsidiaries operating outside the United States. The functional currency for Cadence’s other consolidated entities operating outside of the United States is generally the country’s local currency. Cadence translates the financial statements of consolidated entities whose functional currency is not the United States dollar into United States dollars. Cadence translates assets and liabilities at the exchange rate in effect as of the financial statement date and translates income statement accounts using an average exchange rate for the period. Cadence includes adjustments from translating assets and liabilities into United States dollars, and the effect of exchange rate changes on intercompany transactions of a long-term investment nature in stockholders’ equity as a component of accumulated other comprehensive income. Cadence reports gains and losses from foreign exchange rate changes related to intercompany receivables and payables that are not of a long-term investment nature, as well as gains and losses from foreign currency transactions of a monetary nature in other income (expense), net, in the consolidated income statements. Concentrations of Credit Risk Financial instruments, including derivative financial instruments, that may potentially subject Cadence to concentrations of credit risk, consist principally of cash and cash equivalents, accounts receivable, investments and forward contracts. Credit exposure related to Cadence’s foreign currency forward contracts is limited to the realized and unrealized gains on these contracts. Cash and Cash Equivalents Cadence considers all highly liquid investments with original maturities of three months or less on the date of purchase to be cash equivalents. Receivables Cadence’s receivables, net includes invoiced accounts receivable and the current portion of unbilled receivables. Unbilled receivables represent amounts Cadence has recorded as revenue for which payments from a customer are due over time and Cadence has an unconditional right to the payment. Cadence’s accounts receivable and unbilled receivables were initially recorded at the transaction value. Cadence’s long-term receivables balance includes receivable balances to be invoiced more than one year after each balance sheet date. Allowances for Doubtful Accounts Cadence assesses its ability to collect outstanding receivables and provides customer-specific allowances, allowances for credit losses and general allowances for the portion of its receivables that are estimated to be uncollectible. The allowances are based on the current creditworthiness of its customers, historical experience, expected credit losses, changes in customer demand and the overall economic climate in the industries that Cadence serves. Provisions for these allowances are recorded in general and administrative expense in Cadence’s consolidated income statements. Inventories Inventories are computed at standard costs which approximate actual costs and are valued at the lower of cost or net realizable value based on the first-in, first-out method. Cadence’s inventories include high technology parts and components for complex emulation and prototyping hardware systems. These parts and components are specialized in nature and may be subject to rapid technological obsolescence. While Cadence has programs to manage the required inventories on hand and considers technological obsolescence when estimating required reserves to reduce recorded amounts to market values, it is reasonably possible that such estimates could change in the near term. Cadence’s policy is to reserve for inventory in excess of 12-month demand or for other known obsolescence or realization issues. Property, Plant and Equipment Property, plant and equipment is stated at historical cost. Depreciation and amortization are generally provided over the estimated useful lives, using the straight-line method, as follows: Equipment and internal-use software 2-7 years Buildings 25-32 years Leasehold improvements Shorter of the lease term or the estimated useful life Building improvements and land improvements Up to 32 years Furniture and fixtures 3-5 years Cadence capitalizes certain costs of software developed for internal use. Capitalization of software developed for internal use begins at the application development phase of the project. Amortization begins when the computer software is substantially complete and ready for its intended use. Amortization is recorded on a straight-line basis over the estimated useful life. Capitalized costs were not material during fiscal 2023, 2022 or 2021. Cadence recorded depreciation and amortization expense of $78.4 million, $69.1 million and $71.2 million during fiscal 2023, 2022 and 2021, respectively, for property, plant and equipment. Software Development Costs Software development costs are capitalized beginning when a product’s technological feasibility has been established by completion of a working model of the product and amortization begins when a product is available for general release to customers. The period between the achievement of technological feasibility and the general release of Cadence’s products has typically been of short duration. Costs incurred during fiscal 2023, 2022 and 2021 were not material. Deferred Sales Commissions Cadence records an asset for the incremental costs of obtaining a contract with a customer, including direct sales commissions that are earned upon execution of the contract. Cadence uses the portfolio method to recognize the amortization expense related to these capitalized costs related to initial contracts and renewals and such expense is recognized over a period associated with the revenue of the related portfolio, which is generally two to three years for Cadence’s software arrangements and upon delivery for its hardware and IP arrangements. Incremental costs related to initial contracts and renewals are amortized over the period of the arrangement in each case because Cadence pays the same commission rate for both new contracts and renewals. Deferred sales commissions are tested for impairment on an ongoing basis when events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment is recognized to the extent that the amount of deferred sales commission exceeds the remaining expected gross margin (remaining revenue less remaining direct costs) on the goods and services to which the deferred sales commission relates. Total capitalized costs were $47.6 million and $41.7 million as of December 31, 2023, and December 31, 2022, respectively, and are included in other assets in Cadence’s consolidated balance sheet. Amortization of these assets was $41.4 million, $40.5 million and $40.1 million during fiscal 2023, 2022 and 2021, respectively, and is included in sales and marketing expense in Cadence’s consolidated income statement. Goodwill Cadence conducts a goodwill impairment analysis annually and as necessary if changes in facts and circumstances indicate that the fair value of Cadence’s single reporting unit may be less than its carrying amount. To assess for impairment, Cadence compares the estimated fair value of its single reporting unit to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired, and no further analysis is required. If the fair value of the reporting unit is less than the carrying value of its net assets, Cadence would be required to record an impairment charge. Long-Lived Assets, Including Acquired Intangibles Cadence’s long-lived assets consist of property, plant and equipment, and acquired intangibles. Acquired intangibles consist of acquired technology, certain contract rights, customer relationships, trademarks and trade names, capitalized software, and in-process research and development. These acquired intangibles are acquired through business combinations or direct purchases. Acquired intangibles with definite lives are amortized on a straight-line basis over the estimated economic life of the underlying products and technologies, which range from three years to fifteen years. Acquired intangibles with indefinite lives, or in-process technology, consists of projects that had not reached technological feasibility by the date of acquisition. Upon completion of the project, the assets are amortized over their estimated useful lives. If the project is abandoned rather than completed, the asset is written off. In-process technology is tested for impairment annually and as necessary if changes in facts and circumstances indicate that the assets might be impaired. Cadence reviews its long-lived assets, including acquired intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset or asset group may not be recoverable. Recoverability of an asset or asset group is measured by comparison of its carrying amount to the expected future undiscounted cash flows that the asset or asset group is expected to generate. If it is determined that the carrying amount of an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset or asset group exceeds its fair value. Leases Lessee Considerations Cadence has operating leases primarily consisting of facilities with remaining lease terms of approximately one year to fifteen years. Cadence has options to terminate many of its leases early. The lease term represents the period up to the early termination date unless it is reasonably certain that Cadence will not exercise the early termination option. For certain leases, Cadence has options to extend the lease term for additional periods ranging from one year to ten years. Renewal options are not considered in the remaining lease term unless it is reasonably certain that Cadence will exercise such options. At inception of a contract, Cadence determines an arrangement contains a lease if the arrangement conveys the right to use an identified asset and Cadence obtains substantially all of the economic benefits from the asset and has the ability to direct the use of the asset. Leases with an initial term of twelve months or less are not recorded on the balance sheet. For lease agreements entered into or reassessed after the adoption of Topic 842, Cadence combines the lease and non-lease components in determining the lease liabilities and right-of-use (“ROU”) assets. Non-lease components primarily include common-area maintenance and other management fees. Operating lease expense is generally recognized evenly over the term of the lease. Payments under Cadence's lease agreements are primarily fixed; however, certain agreements contain rental payments that are adjusted periodically based on changes in consumer price and other indices. Changes to payments resulting from changes in indices are expensed as incurred and not included in the measurement of lease liabilities and ROU assets. Cadence’s lease agreements do not provide an implicit borrowing rate, therefore an internal incremental borrowing rate is determined based on information available at lease commencement date for purposes of determining the present value of lease payments. The incremental borrowing rate represents a comparable rate to borrow on a collateralized basis over a similar term and in the economic environment where the leased asset is located. Lessor Considerations Although most of Cadence’s revenue from its hardware business comes from sales of hardware, Cadence also leases its hardware products to some customers. Cadence determines the existence of a lease when the customer controls the use of the identified hardware for a period of time defined in the lease agreement. Cadence’s leases range in duration up to three years with payments generally collected in equal quarterly installments. Cadence’s leases do not include termination rights or variable pricing and typically do not include purchase rights at the end of the lease. Short-term leases are usually less than two years and are classified as operating leases with revenue recognized and depreciation expensed on a straight-line basis over the term of the lease. Long-term leases are typically for three years and are classified as sales-type leases with revenue and cost of sales recognized upon installation. Cadence’s operating leases and sales-type leases contain both lease and non-lease components. Because the pattern of revenue recognition is the same for both the lease and non-lease components in Cadence’s operating leases, Cadence has elected the practical expedient to not separate lease and related non-lease components and accounts for both components under Topic 842. Cadence allocates value to the lease and non-lease components in its sales-type leases using standalone selling prices (“SSPs”) similar to those used under ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” the current accounting standard governing revenue recognition. When Cadence leases its hardware in the same arrangement as software or IP, Cadence allocates value to each performance obligation using SSPs. Investments in Equity Securities Cadence’s investments in marketable equity securities are carried at fair value as a component of prepaid expenses and other in the consolidated balance sheets. Cadence records realized and unrealized holding gains or losses as part of other income (expense), net in the consolidated income statements. Cadence’s non-marketable investments include its investments in privately held companies. These investments are initially recorded at cost and are included in other assets in the consolidated balance sheets. Cadence accounts for these investments using the measurement alternative when the fair value of the investment is not readily determinable, and Cadence does not have the ability to exercise significant influence, or the equity method of accounting when it is determined that Cadence has the ability to exercise significant influence. For investments accounted for using the equity method of accounting, Cadence records its proportionate share of the investee’s income or loss, net of the effects of any basis differences, to other income (expense), net on a one-quarter lag in Cadence’s consolidated income statements. Cadence reviews its non-marketable investments for impairment on a regular basis by considering investee financial performance and other information received from the investee companies that indicates a decline in value has occurred. For non-marketable equity investments accounted for using the measurement alternative, the carrying amount may also be adjusted based on observable price changes from orderly transactions for identical or similar investments of the same issuer. Adjustments to the carrying amounts of non-marketable investments are recorded in other income (expense), net in the consolidated income statements. There were no material events or circumstances impacting the carrying amount of our non-marketable investments during the periods presented. Investments in Debt Securities Cadence’s investments in debt securities are comprised of investments in mortgage-backed and asset backed-securities and are carried at fair value as a component of prepaid expenses and other in the consolidated balance sheets. Cadence classifies its investment in debt securities as available-for-sale, and gross unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on its consolidated balance sheets. Cadence assesses its portfolio of debt securities for impairment at least quarterly. Cadence records an allowance for credit losses on debt securities when the fair value of a debt security is below its amortized cost, and it is more likely than not that Cadence will either sell the impaired security before recovery of its amortized basis or has the intention to sell the security. Provisions for credit losses on impaired debt securities are recorded as a component of other income (expense), net in the consolidated income statements. Derivative Financial Instruments Cadence enters into foreign currency forward exchange contracts with financial institutions to protect against currency exchange risks associated with existing assets and liabilities. A foreign currency forward exchange contract acts as a hedge by increasing in value when underlying assets decrease in value or underlying liabilities increase in value due to changes in foreign exchange rates. Conversely, a foreign currency forward exchange contract decreases in value when underlying assets increase in value or underlying liabilities decrease in value due to changes in foreign exchange rates. The forward contracts are not designated as accounting hedges and, therefore, the unrealized gains and losses are recognized in other income (expense), net, in advance of the actual foreign currency cash flows. The fair value of these forward contracts is recorded in accrued liabilities or in other current assets. These forward contracts generally have maturities of 90 days or less. Nonqualified Deferred Compensation Trust Executive officers, senior management and members of Cadence’s Board of Directors may elect to defer compensation payable to them under Cadence’s Nonqualified Deferred Compensation Plan (“NQDC”). Deferred compensation payments are held in investment accounts and the values of the accounts are adjusted each quarter based on the fair value of the investments held in the NQDC. The selected investments held in the NQDC accounts are carried at fair value, with the unrealized gains and losses recognized in the consolidated income statements as other income (expense), net. These securities are classified in other assets in the consolidated balance sheets because they are not available for Cadence’s use in its operations. Cadence’s obligation with respect to the NQDC trust is recorded in other long-term liabilities on the consolidated balance sheets. Increases and decreases in the NQDC trust liability are recorded as compensation expense in the consolidated income statements. Treasury Stock Cadence generally issues shares related to its stock-based compensation plans from shares held in treasury. When treasury stock is reissued at an amount higher than its cost, the difference is recorded as a component of capital in excess of par in the consolidated statements of stockholders’ equity. When treasury stock is reissued at an amount lower than its cost, the difference is recorded as a component of capital in excess of par to the extent that gains exist to offset the losses. If there are no accumulated treasury stock gains in capital in excess of par, the losses upon reissuance of treasury stock are recorded as a component of retained earnings in the consolidated statements of stockholders’ equity. There were no losses recorded as a component of retained earnings by Cadence on the reissuance of treasury stock during fiscal 2023, 2022 or 2021. The Inflation Reduction Act of 2022, which was enacted into law on August 16, 2022, imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. During fiscal 2023, Cadence recorded excise tax of $0.9 million as a component of treasury stock to account for the incremental cost of the shares repurchased. A corresponding liability for the excise tax payable was recorded as a component of accounts payable and accrued liabilities on Cadence's consolidated balance sheet as of December 31, 2023. Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which Cadence expects to be entitled in exchange for promised goods or services. Cadence’s performance obligations are satisfied either over time or at a point in time. Product and maintenance revenue includes Cadence’s licenses of software and IP, sales of emulation hardware and the related maintenance on these licenses and sales. Services revenue includes revenue received for performing engineering services (which are generally not related to the functionality of other licensed products), customized IP on a fixed fee basis, and sales from cloud-based solutions that provide customers with software, hardware and services over a period of time. Cadence enters into contracts that can include various combinations of licenses, products and services, some of which are distinct and are accounted for as separate performance obligations. For contracts with multiple performance obligations, Cadence allocates the transaction price of the contract to each performance obligation, generally on a relative basis using its SSP. Cadence generates revenue from contracts with customers and applies judgment in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition. Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities. Some customers enter into non-cancelable commitments whereby the customer commits to a fixed dollar amount over a specified period of time that can be used to purchase from a list of products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate selection form to identify the products and services that they are purchasing. Each separate selection form under the arrangement is treated as an individual contract and accounted for based on the respective performance obligations. Cadence records a customer deposit liability for amounts received from customers prior to the arrangement meeting the definition of a revenue contract. Software Revenue Recognition Cadence’s time-based license arrangements grant customers the right to access and use all of the licensed products at the outset of an arrangement and updates are generally made available throughout the entire term of the arrangement, which is generally two to three years. Cadence’s updates provide continued access to evolving technology as customers’ designs migrate to more advanced nodes and as its customers’ technological requirements evolve. In addition, certain time-based license arrangements include remix rights and unspecified additional products that become commercially available during the term of the agreement. Payments are generally received in equal or near equal installments over the term of the agreement. Multiple software licenses, related updates, and technical support in these time-based arrangements constitute a single, combined performance obligation and revenue is recognized over the term of the license, commencing upon the later of the effective date of the arrangement or transfer of the software license. Remix rights are not an additional promised good or service in the contract, and where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support because such rights are provided for the same period of time and have the same time-based pattern of transfer to the customer. Hardware Revenue Recognition Cadence generally has two performance obligations in arrangements involving the sale or lease of hardware products. The first performance obligation is to transfer the hardware product (which includes software integral to the functionality of the hardware product). The second performance obligation is to provide maintenance on hardware and its embedded software, which includes rights to technical support, hardware repairs and software updates that are all provided over the same term and have the same time-based pattern of transfer to the customer. The transaction price allocated to the hardware product is generally recognized as revenue at the time of delivery because the customer obtains control of the product at that point in time. Cadence has concluded that control generally transfers at that point in time because the customer has title to the hardware, physical possession, and a present obligation to pay for the hardware. The transaction price allocated to maintenance is recognized as revenue ratably over the maintenance term. Payments for hardware contracts are generally received upon delivery of the hardware product. Shipping and handling costs are considered fulfillment costs and are included in cost of product and maintenance in Cadence’s consolidated income statements. IP Revenue Recognition Cadence generally licenses IP under nonexclusive license agreements that provide usage rights for specific designs. In addition, for certain of Cadence’s IP license agreements, royalties are collected as customers ship their own products that incorporate Cadence IP. These arrangements generally have two performance obligations—transferring the licensed IP and associated maintenance, which includes rights to technical support, and software updates that are all provided over the maintenance term and have a time-based pattern of transfer to the customer. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery of the IP or the beginning of the license period and revenue allocated to the maintenance is recognized over the maintenance term. Royalties are recognized as revenue in the quarter in which the applicable Cadence customer ships its products that incorporate Cadence IP. Payments for IP contracts are generally received upon delivery of the IP. Cadence customizes certain IP and revenue related to this customization is recognized as services revenue as described below. Services Revenue Recognition Revenue from service contracts is recognized over time, generally using costs incurred or hours expended to measure progress. Cadence has a history of accurately estimating project status and the costs necessary to complete projects. A number of internal and external factors can affect these estimates, including labor rates, utilization and efficiency variances and specification and testing requirement changes. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources. Stock-Based Compensation Cadence recognizes the cost of awards of equity instruments granted to employees in exchange for their services as stock-based compensation expense. Stock-based compensation expense is measured at the grant date based on the value of the award and is recognized as expense over the requisite service period, which is typically the vesting period. Cadence recognizes stock-based compensation expense on the straight-line method for awards that only contain a service condition and on the graded-vesting method for awards that contain both a service and performance condition. Cadence recognizes the impact of forfeitures on stock-based compensation expense as they occur. The fair value of stock options and purchase rights issued under Cadence’s Employee Stock Purchase Plan (“ESPP”) are calculated using the Black-Scholes option pricing model. The computation of the expected volatility assumption used for new awards is based on a weighting of historical and implied volatilities. When determining the expected term, Cadence reviews historical employee exercise behavior from options having similar vesting periods. The risk-free interest rate for the period within the expected term of the option is based on the yield of United States Treasury notes for the comparable term in effect at the time of grant. The expected dividend yield used in the calculation is zero because Cadence has not historically paid and currently does not expect to pay dividends in the foreseeable future. The fair value of market-based performance stock awards is calculated using a Monte Carlo simulation model and takes into account the same input assumptions as the Black-Scholes model, as well as the possibility that the market conditions may not be satisfied. Cadence recognizes stock-based compensation expense on the graded-vesting method for market-based performance stock awards. Advertising Cadence expenses the costs of advertising as incurred. Total advertising expense, including marketing programs and events, was $21.7 million, $17.0 million and $7.5 million during fiscal 2023, 2022 and 2021, respectively, and is included in marketing and sales in the consolidated income statements. Restructuring Cadence records personnel-related restructuring charges with termination benefits when the costs are both probable and estimable. Cadence records personnel-related restructuring charges with non-customary termination benefits when the plan has been communicated to the affected employees. Cadence generally begins recording facilities-related restructuring charges in the period in which a formal plan to vacate an affected facility is established. In connection with facilities-related restructuring plans, Cadence has made certain assumptions and estimates related to facilities, particularly the timing of exit and the ability to sublease. Facility closure costs in restructuring charges primarily includes accelerated ROU asset amortization, lease buyout costs and certain contractual costs to maintain facilities during the period after abandonment.

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Cadence groups its products and services into five categories related to major design activities. The following table shows the percentage of revenue contributed by each of Cadence’s five product categories for fiscal 2023, 2022 and 2021: 2023 2022 2021 Custom IC Design and Simulation 22 % 22 % 23 % Digital IC Design and Signoff 27 % 28 % 29 % Functional Verification, including Emulation and Prototyping Hardware* 27 % 26 % 24 % IP 12 % 12 % 13 % System Design and Analysis 12 % 12 % 11 % Total 100 % 100 % 100 % _____________ * Includes immaterial amount of revenue accounted for under leasing arrangements. Cadence generates revenue from contracts with customers and applies judgment in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition. Certain of Cadence’s licensing arrangements allow customers the ability to remix among software products. Cadence also has arrangements with customers that include a combination of products, with the actual product selection and number of licensed users to be determined at a later date. For these arrangements, Cadence estimates the allocation of the revenue to product categories based upon the expected usage of products. Revenue by product category fluctuates from period to period based on demand for products and services, and Cadence’s available resources to deliver them. No single customer accounted for 10% or more of total revenue during fiscal 2023, 2022 or 2021. Recurring revenue includes revenue recognized over time from Cadence’s software arrangements, services, royalties, maintenance on IP licenses and hardware, and operating leases of hardware. Recurring revenue also includes revenue recognized at varying points in time over the term of other arrangements with non-cancelable commitments, whereby the customer commits to a fixed dollar amount over a specified period of time that can be used to purchase from a list of products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate selection form to identify the products and services that they are purchasing. Each separate selection form under the arrangement is treated as an individual contract and accounted for based on the respective performance obligations. The remainder of Cadence’s revenue is recognized at a point in time and is characterized as up-front revenue. Up-front revenue is primarily generated by sales of emulation and prototyping hardware and individual IP licenses. The percentage of Cadence’s recurring and up-front revenue is impacted by delivery of hardware and IP products to its customers in any single fiscal period. The following table shows the percentage of Cadence’s revenue that is classified as recurring or up-front for fiscal 2023, 2022 and 2021: 2023 2022 2021 Revenue recognized over time 81 % 83 % 85 % Revenue from arrangements with non-cancelable commitments 3 % 2 % 3 % Recurring revenue 84 % 85 % 88 % Up-front revenue 16 % 15 % 12 % Total 100 % 100 % 100 % Significant Judgments Cadence’s contracts with customers often include promises to transfer to a customer multiple software and/or IP licenses and services, including professional services, technical support services, and rights to unspecified updates. Determining whether licenses and services are distinct performance obligations that should be accounted for separately, or not distinct and thus accounted for together, requires significant judgment. In some arrangements, such as most of Cadence’s IP license arrangements, Cadence has concluded that the licenses and associated services are distinct from each other. In others, like Cadence’s time-based software arrangements, the licenses and certain services are not distinct from each other. Cadence’s time-based software arrangements include multiple software licenses and updates to the licensed software products, as well as technical support, and Cadence has concluded that these promised goods and services are a single, combined performance obligation. The accounting for contracts with multiple performance obligations requires the contract’s transaction price to be allocated to each distinct performance obligation based on relative SSP. Judgment is required to determine the SSP for each distinct performance obligation because Cadence rarely licenses or sells products on a standalone basis. In instances where the SSP is not directly observable because Cadence does not sell the license, product or service separately, Cadence determines the SSP using information that maximizes the use of observable inputs and may include market conditions. Cadence typically has more than one SSP for individual performance obligations due to the stratification of those items by classes of customers and circumstances. In these instances, Cadence may use information such as the size of the customer and geographic region of the customer in determining the SSP. Revenue is recognized over time for Cadence’s combined performance obligations that include software licenses, updates, technical support and maintenance that are separate performance obligations with the same term. For Cadence’s professional services, revenue is recognized over time, generally using costs incurred or hours expended to measure progress. Judgment is required in estimating project status and the costs necessary to complete projects. A number of internal and external factors can affect these estimates, including labor rates, utilization and efficiency variances and specification and testing requirement changes. For Cadence’s other performance obligations recognized over time, revenue is generally recognized using a time-based measure of progress reflecting generally consistent efforts to satisfy those performance obligations throughout the arrangement term. If a group of agreements are so closely related that they are, in effect, part of a single arrangement, such agreements are deemed to be one arrangement for revenue recognition purposes. Cadence exercises significant judgment to evaluate the relevant facts and circumstances in determining whether the separate agreements should be accounted for separately or as, in substance, a single arrangement. Cadence’s judgments about whether a group of contracts comprise a single arrangement can affect the allocation of consideration to the distinct performance obligations, which could have an effect on results of operations for the periods involved. Cadence is required to estimate the total consideration expected to be received from contracts with customers. In limited circumstances, the consideration expected to be received is variable based on the specific terms of the contract or based on Cadence’s expectations of the term of the contract. Generally, Cadence has not experienced significant returns or refunds to customers. These estimates require significant judgment and a change in these estimates could have an effect on its results of operations during the periods involved. Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers, and these timing differences result in receivables, contract assets, or contract liabilities (deferred revenue) on Cadence’s consolidated balance sheets. For certain software, hardware and IP agreements with payment plans, Cadence records an unbilled receivable related to revenue recognized upon transfer of control because it has an unconditional right to invoice and receive payment in the future related to those transferred products or services. Cadence records a contract asset when revenue is recognized prior to invoicing and Cadence does not have the unconditional right to invoice or retains performance risk with respect to that performance obligation. Cadence records deferred revenue when revenue is recognized subsequent to invoicing. For Cadence’s time-based software agreements, customers are generally invoiced in equal, quarterly amounts, although some customers prefer to be invoiced in single or annual amounts. The contract assets indicated below are included in prepaid expenses and other in the consolidated balance sheets and primarily relate to Cadence’s rights to consideration for work completed but not billed as of the balance sheet date on services and customized IP contracts. The contract assets are transferred to receivables when the rights become unconditional, usually upon completion of a milestone. Cadence’s contract balances as of December 31, 2023, and December 31, 2022, were as follows: As of December 31, December 31, (In thousands) Contract assets $ 17,554 $ 22,766 Deferred revenue 763,955 782,062 Cadence recognized revenue of $689.7 million, $540.7 million and $430.2 million during fiscal 2023, 2022 and 2021, respectively, that was included in the deferred revenue balance at the beginning of each fiscal year. All other activity in deferred revenue, with the exception of deferred revenue assumed from acquisitions, is due to the timing of invoices in relation to the timing of revenue as described above. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days. In instances where the timing of revenue recognition differs from the timing of invoicing, Cadence has determined that its contracts generally do not include a significant financing component. The primary purpose of invoicing terms is to provide customers with simplified and predictable ways of purchasing Cadence’s products and services, and not to facilitate financing arrangements. Remaining Performance Obligations Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied, which includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods. Cadence has elected to exclude the potential future royalty receipts from the remaining performance obligations. Contracted but unsatisfied performance obligations were approximately $6.0 billion as of December 31, 2023, which included $0.4 billion of non-cancelable commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. Cadence estimates its remaining performance obligations at a point in time. Actual amounts and timing of revenue recognition may differ from these estimates largely due to changes in actual installation and delivery dates, as well as contract renewals, modifications and terminations. As of December 31, 2023, Cadence expected to recognize 56% of the contracted but unsatisfied performance obligations, excluding non-cancelable commitments, as revenue over the next 12 months, 39% over the next 13 to 36 months and the remainder thereafter. Cadence recognized revenue of $55.0 million, $52.8 million and $47.1 million during fiscal 2023, 2022 and 2021, respectively, from performance obligations satisfied in previous periods. These amounts represent royalties earned during the period and exclude contracts with nonrefundable prepaid royalties. Nonrefundable prepaid royalties are recognized upon delivery of the IP because Cadence’s right to the consideration is not contingent upon customers’ future shipments.

Debt Disclosure [Abstract]
DEBT	DEBT Cadence’s outstanding debt as of December 31, 2023, and December 31, 2022, was as follows: December 31, 2023 December 31, 2022 (In thousands) Principal Unamortized Discount Carrying Value Principal Unamortized Discount Carrying Value Revolving Credit Facility $ — $ — $ — $ 100,000 $ — $ 100,000 2024 Notes 350,000 (715) 349,285 350,000 (1,581) 348,419 2025 Term Loan 300,000 (229) 299,771 300,000 (341) 299,659 Total outstanding debt $ 650,000 $ (944) $ 649,056 $ 750,000 $ (1,922) $ 748,078 Revolving Credit Facility In June 2021, Cadence entered into a five-year senior unsecured revolving credit facility with a group of lenders led by Bank of America, N.A., as administrative agent (the “2021 Credit Facility”). In September 2022, Cadence amended the 2021 Credit Facility to, among other things, allow Cadence to change its fiscal year to match the calendar year commencing in 2023 and change the interest rate benchmark for loans under the 2021 Credit Facility from the London Inter-Bank Offered Rate (“LIBOR”) to Term Secured Overnight Financing Rate (“SOFR”). The material terms of the 2021 Credit Facility otherwise remain unchanged. The 2021 Credit Facility provides for borrowings up to $700 million, with the right to request increased capacity up to an additional $350 million upon the receipt of lender commitments, for total maximum borrowings of $1.05 billion. The 2021 Credit Facility expires on June 30, 2026. Any outstanding loans drawn under the 2021 Credit Facility are due at maturity on June 30, 2026, subject to an option to extend the maturity date. Outstanding borrowings may be repaid at any time prior to maturity. Debt issuance costs of $1.3 million were recorded to other assets in Cadence’s consolidated balance sheet at the inception of the agreement and are being amortized to interest expense over the term of the 2021 Credit Facility. Interest accrues on borrowings under the 2021 Credit Facility at a rate equal to, at Cadence’s option, either (1) SOFR plus a margin between 0.750% and 1.250% per annum, determined by reference to the credit rating of Cadence’s unsecured debt, plus a SOFR adjustment of 0.10% or (2) the base rate plus a margin between 0.000% and 0.250% per annum, determined by reference to the credit rating of Cadence’s unsecured debt. Interest is payable quarterly. A commitment fee ranging from 0.070% to 0.175% is assessed on the daily average undrawn portion of revolving commitments. Borrowings bear interest at what is estimated to be current market rates of interest. Accordingly, the carrying value of the 2021 Credit Facility approximates fair value. The 2021 Credit Facility contains customary negative covenants that, among other things, restrict Cadence’s ability to incur additional indebtedness, grant liens and make certain asset dispositions. In addition, the 2021 Credit Facility contains financial covenants that require Cadence to maintain a funded debt to EBITDA ratio not greater than 3.25 to 1, with a step up to 3.75 to 1 for one year following an acquisition by Cadence of at least $250 million that results in a pro forma leverage ratio between 3.00 to 1 and 3.50 to 1. As of December 31, 2023, Cadence was in compliance with all financial covenants associated with the 2021 Credit Facility. 2024 Notes In October 2014, Cadence issued a $350.0 million aggregate principal amount of 4.375% Senior Notes due October 15, 2024 (the “2024 Notes”). Cadence received net proceeds of $342.4 million from the issuance of the 2024 Notes, net of a discount of $1.4 million and issuance costs of $6.2 million. Both the discount and issuance costs are being amortized to interest expense over the term of the 2024 Notes using the effective interest method. The net balance of the 2024 notes of $349.3 million was classified as a current liability on Cadence’s consolidated balance sheet as of December 31, 2023. Interest is payable in cash semi-annually in April and October. The 2024 Notes are unsecured and rank equal in right of payment to all of Cadence’s existing and future senior indebtedness. The fair value of the 2024 Notes was approximately $347.2 million as of December 31, 2023. Cadence may redeem the 2024 Notes, in whole or in part, at a redemption price equal to the greater of (a) 100% of the principal amount of the notes to be redeemed and (b) the sum of the present values of the remaining scheduled payments of principal and interest, plus any accrued and unpaid interest, as more particularly described in the indenture governing the 2024 Notes. The indenture governing the 2024 Notes includes customary representations, warranties and restrictive covenants, including, but not limited to, restrictions on Cadence’s ability to grant liens on assets, enter into sale and lease-back transactions, or merge, consolidate or sell assets, and also includes customary events of default. 2025 Term Loan In September 2022, Cadence entered into a $300.0 million three-year senior non-amortizing term loan facility due on September 7, 2025, with a group of lenders led by Bank of America, N.A., as administrative agent (the “2025 Term Loan”). The 2025 Term Loan is unsecured and ranks equal in right of payment to all of Cadence’s unsecured indebtedness. Proceeds from the loan were used to fund Cadence’s acquisition of OpenEye Scientific Software, Inc. (“OpenEye”). Debt issuance costs associated with the 2025 Term Loan were not material. Amounts outstanding under the 2025 Term Loan accrue interest at a rate equal to, at Cadence’s option, either (1) Term SOFR plus a margin between 0.625% and 1.125% per annum, determined by reference to the credit rating of Cadence’s unsecured debt, plus a SOFR adjustment of 0.10% or (2) base rate plus a margin between 0.000% and 0.125% per annum, determined by reference to the credit rating of Cadence’s unsecured debt. As of December 31, 2023, the interest rate on the 2025 Term Loan was 6.21%. Interest is payable quarterly. Borrowings bear interest at what is estimated to be current market rates of interest. Accordingly, the carrying value of the 2025 Term Loan approximates fair value. The 2025 Term Loan contains customary negative covenants that, among other things, restrict Cadence’s ability to incur additional indebtedness, grant liens and make certain asset dispositions. In addition, the 2025 Term Loan contains a financial covenant that requires Cadence to maintain a funded debt to EBITDA ratio not greater than 3.25 to 1, with a step-up to 3.75 to 1 for one year following an acquisition by Cadence of at least $250 million that results in a pro forma leverage ratio between 3.00 to 1 and 3.50 to 1. As of December 31, 2023, Cadence was in compliance with all financial covenants associated with the 2025 Term Loan.

INCOME TAXES	INCOME TAXES The United States enacted the Tax Cuts and Jobs Act in December 2017, which required companies to capitalize all of their research and development (“R&D”) costs, including software development costs, incurred in tax years beginning after December 31, 2021. Beginning in fiscal 2022, Cadence began capitalizing and amortizing R&D costs over five years for domestic research and fifteen years for international research rather than expensing these costs as incurred. The mandatory capitalization requirement increased Cadence’s fiscal 2023 and 2022 effective tax rates, deferred tax assets, and cash tax payments. Cadence’s income before provision for income taxes included income from the United States and from foreign subsidiaries for fiscal 2023, 2022 and 2021, was as follows: 2023 2022 2021 (In thousands) United States $ 533,442 $ 402,083 $ 376,037 Foreign subsidiaries 748,484 643,280 392,398 Total income before provision for income taxes $ 1,281,926 $ 1,045,363 $ 768,435 Cadence’s provision for income taxes was comprised of the following items for fiscal 2023, 2022 and 2021: 2023 2022 2021 (In thousands) Current: Federal $ 156,495 $ 212,380 $ 19,957 State and local 15,933 7,280 25,246 Foreign 104,866 84,357 70,455 Total current 277,294 304,017 115,658 Deferred: Federal (87,851) (79,170) (16,415) State and local 25,440 (50,640) (30,406) Foreign 25,899 22,204 3,643 Total deferred (36,512) (107,606) (43,178) Total provision for income taxes $ 240,782 $ 196,411 $ 72,480 During fiscal 2023, Cadence recognized a tax benefit of approximately $24.8 million due to the recognition of previously unrecognized tax benefits from the expiration of the applicable statute of limitations and a tax benefit of approximately $14.0 million primarily related to a change in R&D expenses that were capitalized in fiscal 2022. During fiscal 2022, Cadence recognized a tax benefit of approximately $68.7 million due to a release of the valuation allowance on its California research and development tax credit deferred tax assets. In evaluating its ability to realize its deferred tax assets, Cadence considered all available positive and negative evidence, including its past operating results, forecasted earnings, future taxable income, and prudent and feasible tax planning strategies. Cadence expects to utilize these tax credits based on current earnings and future taxable income projections. During fiscal 2021, Cadence recognized a tax benefit of approximately $10.5 million due to a release of the valuation allowance on its Massachusetts research and development tax credit deferred tax assets. Cadence expects to utilize these tax credits prior to expiration based on current earnings and future taxable income projections.

The valuation allowance primarily relates to the following: • Tax credits in certain states that are accumulating at a rate greater than Cadence’s capacity to utilize the credits and tax credits in certain states where it is likely the credits will expire unused; • Federal, state and foreign deferred tax assets related to investments and capital losses that can only be utilized against gains that are capital in nature; and • Foreign tax credits that can only be fully utilized if Cadence has sufficient income of a specific character in the future. The valuation allowance increased by $9.1 million during fiscal 2023, and decreased by $38.1 million and $8.3 million during fiscal 2022 and fiscal 2021, respectively. The valuation allowance activity was primarily related to state research and development tax credits and certain foreign tax credits. As of December 31, 2023, Cadence’s operating loss carryforwards were as follows: Amount Expiration Periods (In thousands) Federal $ 167 from 2027 through 2033 California 28,437 from 2025 through 2041 Other states (tax effected, net of federal benefit) 762 from 2024 through indefinite Foreign (tax effected) 6,719 indefinite As of December 31, 2023, Cadence had tax credit carryforwards of: Amount Expiration Periods (In thousands) Federal* $ 42,905 from 2031 California 33,542 indefinite Other states 11,065 from 2031 through indefinite Foreign 42,002 from 2042 through indefinite _____________ *Certain of Cadence’s foreign tax credits have yet to be realized and as a result do not yet have an expiration period. Examinations by Tax Authorities Taxing authorities regularly examine Cadence’s income tax returns. As of December 31, 2023, Cadence’s earliest tax years that remain open to examination and the assessment of additional tax include: Jurisdiction Earliest Tax Year Open to Examination United States – Federal 2017 United States – California 2019 Ireland 2019 Israel 2017 Korea 2019 Unrecognized Tax Benefits The changes in Cadence’s gross amount of unrecognized tax benefits during fiscal 2023, 2022 and 2021 are as follows: 2023 2022 2021 (In thousands) Unrecognized tax benefits at the beginning of the fiscal year $ 126,073 $ 130,530 $ 113,021 Gross amount of the increase (decrease) in unrecognized tax benefits of tax positions taken during a prior year* (1,401) 2,152 15,414 Gross amount of the increases in unrecognized tax benefits as a result of tax positions taken during the current year 2,565 2,660 5,100 Amount of decreases in unrecognized tax benefits relating to settlements with taxing authorities, including the utilization of tax attributes (8,000) — (270) Reductions to unrecognized tax benefits resulting from the lapse of the applicable statute of limitations (24,768) (7,430) (2,778) Effect of foreign currency translation (158) (1,839) 43 Unrecognized tax benefits at the end of the fiscal year $ 94,311 $ 126,073 $ 130,530 Total amounts of unrecognized tax benefits that, if upon resolution of the uncertain tax positions would reduce Cadence’s effective tax rate $ 93,398 $ 121,415 $ 79,654 _____________ * Includes unrecognized tax benefits of tax positions recorded in connection with acquisitions Cadence is currently under examination or contesting proposed adjustments by various domestic and international taxing authorities. It is reasonably possible that the amount of unrecognized tax positions could decrease by approximately $4.9 million during the next 12 months. The potential decrease could be a combination of settlements with tax authorities and expiration of statute of limitations. The actual amount could vary significantly depending on the ultimate timing and nature of any settlements or examinations in advance of statute of limitation expirations.

Options granted under the Omnibus Plan have an exercise price not less than the fair market value of the stock on the date of grant. Options and restricted stock generally vest over a period of three years to four years. Options granted under the Omnibus Plan expire seven years from the date of grant. Vesting of restricted stock awards granted under the Omnibus Plan may require the attainment of specified performance criteria. Cadence’s 1995 Directors Stock Incentive Plan (the “Directors Plan”) provides for the issuance of non-qualified options, restricted stock awards and restricted stock units to its non-employee directors. Options granted under the Directors Plan have an exercise price not less than the fair market value of the stock on the date of grant. As of December 31, 2023, the total number of shares available for future issuance under the Directors Plan was 0.4 million. Options granted under the Directors Plan expire after ten years, and options, restricted stock awards and restricted stock units vest one year from the date of grant. Cadence has assumed certain options granted to employees of acquired companies (“Acquired Options”). The Acquired Options were assumed by Cadence outside of its stock option plans, and each option is administered under the terms of the respective original plans of the acquired companies. All of the Acquired Options have been adjusted for the price conversion under the terms of the acquisition agreement between Cadence and the relevant acquired company. If the Acquired Options are canceled, forfeited or expire, they do not become available for future grant. Stock-Based Compensation Stock-based compensation expense and the related income tax benefit recognized in connection with stock options, restricted stock and the ESPP during fiscal 2023, 2022 and 2021 were as follows: 2023 2022 2021 (In thousands) Stock options $ 15,939 $ 14,597 $ 9,051 Restricted stock 278,567 224,887 181,946 ESPP 31,105 30,955 19,093 Total stock-based compensation expense $ 325,611 $ 270,439 $ 210,090 Income tax benefit $ 50,994 $ 40,612 $ 33,958 Stock-based compensation expense is reflected in Cadence’s consolidated income statements during fiscal 2023, 2022 and 2021 as follows: 2023 2022 2021 (In thousands) Cost of product and maintenance $ 4,500 $ 3,818 $ 3,375 Cost of services 5,728 4,851 4,161 Marketing and sales 66,304 54,771 43,264 Research and development 194,709 158,937 131,247 General and administrative 54,370 48,062 28,043 Total stock-based compensation expense $ 325,611 $ 270,439 $ 210,090 Stock Options The exercise price of each stock option granted under Cadence’s employee equity incentive plans is equal to or greater than the closing price of Cadence’s common stock on the date of grant. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The weighted average grant date fair value of options granted, and the weighted average assumptions used in the model for fiscal 2023, 2022 and 2021 were as follows: 2023 2022 2021 Dividend yield None None None Expected volatility 32.6 % 36.0 % 31.7 % Risk-free interest rate 3.62 % 2.14 % 1.02 % Expected term (in years) 5.0 4.8 4.8 Weighted average fair value of options granted $ 71.83 $ 49.16 $ 46.10 A summary of the changes in stock options outstanding under Cadence’s equity incentive plans during fiscal 2023 is presented below: Weighted Average Weighted Average Remaining Contractual Terms Aggregate Intrinsic Shares Exercise Price (Years) Value (In thousands) (In thousands) Options outstanding as of December 31, 2022 2,915 $ 80.35 Granted 262 205.87 Exercised (797) 38.82 Forfeited (13) 131.94 Options outstanding as of December 31, 2023 2,367 $ 107.93 3.5 $ 389,178 Options vested as of December 31, 2023 1,763 $ 85.79 2.8 $ 328,927 Cadence had total unrecognized compensation expense related to stock option grants of $32.9 million as of December 31, 2023, which will be recognized over the remaining vesting period. The remaining weighted average vesting period of unvested awards is 2.3 years. The total intrinsic value of and cash received from options exercised during fiscal 2023, 2022 and 2021 was: 2023 2022 2021 (In thousands) Intrinsic value of options exercised $ 139,125 $ 105,242 $ 129,403 Cash received from options exercised 30,940 16,014 23,844 Restricted Stock Generally, restricted stock, which includes restricted stock awards and restricted stock units, vests over three years to four years and is subject to the employee’s continuing service to Cadence. Stock-based compensation expense is recognized ratably over the vesting term. The vesting of certain restricted stock grants is subject to attainment of specified performance criteria. Each fiscal quarter, Cadence estimates the probability of the achievement of these performance goals and recognizes any related stock-based compensation expense using the graded-vesting method. The amount of stock-based compensation expense recognized in any one period can vary based on the attainment or expected attainment of the various performance goals. If such performance goals are not ultimately met, no compensation expense is recognized and any previously recognized compensation expense is reversed. Certain long-term, market-based stock awards granted to executives vest over three to five years and are subject to certain market conditions and the executive’s continuing service to Cadence. Vesting of the market-based awards is contingent upon achieving market conditions of total shareholder return relative to a peer index. Stock-based compensation expense is recognized using the graded-vesting method over the vesting term. If the market-based conditions are not ultimately met, compensation expense previously recognized is not reversed. As of December 31, 2023, Cadence had 2.4 million shares of unvested long-term, market-based stock awards outstanding. Cadence granted market-based awards in fiscal 2023 and fiscal 2022. No market-based awards were granted in fiscal 2021. Compensation expense is calculated using the fair value of the market-based stock awards under Monte Carlo simulation model. The weighted average assumptions used in the model for fiscal 2023 and fiscal 2022 were as follows: 2023 2022 Dividend yield None None Expected volatility 33.6 % 29.1 % Risk-free interest rate 3.64 % 1.98 % Expected term (in years) 3.8 5.1 Weighted average fair value of market-based awards granted $ 132.20 $ 51.34 Stock-based compensation expense related to performance-based restricted stock grants and market-based restricted stock grants for fiscal 2023, 2022 and 2021 was as follows: 2023 2022 2021 (In thousands) Stock-based compensation expense related to performance-based restricted stock $ 22,922 $ 17,753 $ 16,225 Stock-based compensation expense related to market-based stock awards 30,095 25,259 6,453 A summary of the changes in restricted stock outstanding under Cadence’s equity incentive plans during fiscal 2023 is presented below: Weighted Average Grant Date Aggregate Intrinsic Shares Fair Value Value (In thousands) (In thousands) Unvested shares as of December 31, 2022 6,371 $ 99.03 Granted 1,546 233.78 Vested (2,052) 115.26 Forfeited (268) 118.97 Unvested shares as of December 31, 2023 5,597 $ 129.35 $ 1,138,797 As of December 31, 2023, Cadence had total unrecognized compensation expense related to restricted stock grants of $547.2 million, which will be recognized over a weighted average vesting period of 1.8 years. The total fair value realized by employees upon vesting of restricted stock during fiscal 2023, 2022 and 2021 was: 2023 2022 2021 (In thousands) Fair value of restricted stock realized upon vesting $ 442,556 $ 346,003 $ 365,298 Employee Stock Purchase Plan Cadence provides an ESPP that enables eligible employees to purchase shares of its common stock. Offering periods under the plan last a duration of six months beginning on either February 1 or August 1, with the purchase dates falling on the last day of the six-month offering period. For the offering periods commencing after February 1, 2022, eligible employees may purchase Cadence’s common stock at a price equal to 85% of the lower of the fair market value at the beginning or the end of the applicable offering period, in an amount not to exceed 15% of their annual base earnings plus bonuses and commissions, and subject to a limit in any calendar year of $25,000. The ESPP may be amended from time to time. As of December 31, 2023, the total number of shares available for future issuance under the ESPP was 3.3 million. Compensation expense is calculated using the fair value of the employees’ purchase rights under the Black-Scholes option pricing model. The weighted average grant date fair value of purchase rights granted under the ESPP and the weighted average assumptions used in the model for fiscal 2023, 2022 and 2021 were as follows: 2023 2022 2021 Dividend yield None None None Expected volatility 29.9 % 37.2 % 31.5 % Risk-free interest rate 4.50 % 1.71 % 0.07 % Expected term (in years) 0.5 0.5 0.5 Weighted average fair value of options granted $ 50.95 $ 43.41 $ 33.77 Shares of common stock issued under the ESPP for fiscal 2023, 2022 and 2021 were as follows: 2023 2022 2021 (In thousands, except per share amounts) Cadence shares purchased under the ESPP 647 703 624 Cash received for the purchase of shares under the ESPP $ 102,017 $ 89,314 $ 63,932 Weighted average purchase price per share $ 157.70 $ 127.12 $ 102.41 Reserved for Future Issuance As of December 31, 2023, Cadence had reserved the following shares of authorized but unissued common stock for future issuance: Shares (In thousands) Employee equity incentive plans* 21,028 Employee stock purchase plans 3,280 Directors stock plans* 458 Total 24,766 _____________ *Includes shares reserved for: (i) issuance upon exercise of future option grants, (ii) issuance upon vesting of future restricted stock grants, (iii) outstanding but unexercised options to purchase common stock, or (iv) unvested restricted stock units.

STOCK REPURCHASE PROGRAMS	STOCK REPURCHASE PROGRAMS In August 2023, Cadence’s Board of Directors increased the prior authorization to repurchase shares of Cadence common stock by authorizing an additional $1.0 billion. The actual timing and amount of repurchases are subject to business and market conditions, corporate and regulatory requirements, stock price, acquisition opportunities and other factors. During fiscal 2023, Cadence repurchased approximately 2.3 million shares on the open market, for an aggregate purchase price of 500.0 million. In June 2023, Cadence also entered into an accelerated share repurchase (“ASR”) agreement with HSBC Bank USA, National Association (“HSBC”) to repurchase an aggregate of $200.0 million of Cadence common stock. The ASR agreement was accounted for as two separate transactions (1) a repurchase of common stock and (2) an equity-linked contract on Cadence’s own stock. In June 2023, Cadence received an initial share delivery of approximately 0.6 million shares, which represented the number of shares at a market price equal to $140.0 million. An equity-linked contract for $60 million, representing the remaining shares to be delivered by HSBC under the ASR agreement, was recorded to stockholders' equity as of June 30, 2023. In August 2023, the ASR agreement settled and resulted in a delivery of approximately 0.3 million additional shares to Cadence. In total, Cadence received approximately 0.9 million shares under the ASR agreement at an average price per share of $228.26. The shares received were treated as repurchased common stock for purposes of calculating earnings per share. As of December 31, 2023, approximately $1.4 billion of the share repurchase authorization remained available to repurchase shares of Cadence common stock. In June 2022, Cadence also entered into an ASR agreement with Royal Bank of Canada to repurchase an aggregate of $100.0 million of Cadence common stock. The ASR agreement was accounted for as two separate transactions (1) a repurchase of common stock and (2) an equity-linked contract on Cadence’s own stock. In June 2022, Cadence received an initial share delivery of approximately 0.5 million shares, which represented the number of shares at a market price equal to $70.0 million. An equity-linked contract for $30.0 million, representing the remaining shares to be delivered by Royal Bank of Canada under the ASR agreement, was recorded to stockholders’ equity. In September 2022, the ASR agreement settled and resulted in a delivery to Cadence of approximately 0.1 million additional shares. In total, approximately 0.6 million shares were repurchased under the ASR agreement at an average price per share of $167.07. The shares received were treated as a repurchase of common stock for purposes of calculating earnings per share. The shares repurchased under Cadence’s repurchase authorizations and the total cost of repurchased shares, including commissions, during fiscal 2023, 2022 and 2021 were as follows: 2023* 2022** 2021 (In thousands) Shares repurchased 3,145 6,602 4,401 Total cost of repurchased shares $ 700,134 $ 1,050,091 $ 612,297 _____________ *Includes 276 thousand shares and $60 million equity forward contract from the June 2023 ASR settled in August 2023, and excludes $0.9 million of excise tax. **Includes 109 thousand shares and $30 million equity forward contract from the June 2022 ASR settled in September 2022.

Restructuring and Related Activities [Abstract]
RESTRUCTURING AND OTHER CHARGES	RESTRUCTURING AND OTHER CHARGES Cadence has initiated various restructuring plans in recent years in an effort to better align its resources with its business strategy. Most recently, in August 2023, Cadence initiated a restructuring plan (the “2023 Restructuring Plan”) and incurred costs comprised of severance payments and termination benefits related to headcount reductions and costs related to impacted facilities. Cadence expects to incur facility-related restructuring charges in future periods until all affected leases are terminated. These facility-related charges are not expected to be material. These costs are included in restructuring on Cadence’s consolidated income statements. The following table presents activity for Cadence’s restructuring plans during fiscal 2023, 2022 and 2021: Severance and Benefits Excess Facilities Total (In thousands) Balance, January 2, 2021 $ 7,321 $ 1,372 $ 8,693 Restructuring (1,480) 432 (1,048) Cash payments (5,774) (1,761) (7,535) Effect of foreign currency translation (67) — (67) Balance, January 1, 2022 $ — $ 43 $ 43 Restructuring — 55 55 Cash payments — (98) (98) Effect of foreign currency translation — — — Balance, December 31, 2022 $ — $ — $ — Restructuring 10,935 78 11,013 Non-cash changes — (78) (78) Cash payments (8,211) — (8,211) Effect of foreign currency translation (121) — (121) Balance, December 31, 2023 $ 2,603 $ — $ 2,603 All liabilities for severance and related benefits under the 2023 Restructuring Plan are included in accounts payable and accrued liabilities on Cadence’s consolidated balance sheet as of December 31, 2023. Cadence expects to make cash payments to settle these liabilities through fiscal 2024. Other Termination Benefits During fiscal 2021, Cadence offered a voluntary retirement program to eligible employees in the United States. This program resulted in a one-time charge of $26.8 million for voluntary termination and post-employment benefits. These charges were included in cost of revenue and each of the operating expense categories included in Cadence’s consolidated income statements. As of December 31, 2023, there were no remaining liabilities related to the voluntary retirement program on Cadence’s consolidated balance sheet.

NET INCOME PER SHARE	NET INCOME PER SHARE Basic net income per share is computed by dividing net income during the period by the weighted average number of shares of common stock outstanding during that period, less unvested restricted stock awards. Diluted net income per share is impacted by equity instruments considered to be potential common shares, if dilutive, computed using the treasury stock method of accounting. The calculations for basic and diluted net income per share for fiscal 2023, 2022 and 2021 are as follows: 2023 2022 2021 (In thousands, except per share amounts) Net income $ 1,041,144 $ 848,952 $ 695,955 Weighted average common shares used to calculate basic net income per share 269,381 271,198 273,504 Stock-based awards 3,367 3,813 5,354 Weighted average common shares used to calculate diluted net income per share 272,748 275,011 278,858 Net income per share – basic $ 3.86 $ 3.13 $ 2.54 Net income per share – diluted $ 3.82 $ 3.09 $ 2.50 The following table presents shares of Cadence’s common stock outstanding for fiscal 2023, 2022 and 2021 that were excluded from the computation of diluted net income per share because the effect of including these shares in the computation of diluted net income per share would have been anti-dilutive: 2023 2022 2021 (In thousands) Long-term market-based awards 1,381 1,565 — Options to purchase shares of common stock 345 716 214 Non-vested shares of restricted stock 232 88 41 Total potential common shares excluded 1,958 2,369 255

INVESTMENTS	INVESTMENTS Marketable Equity Investments Cadence’s investments in marketable equity securities consist of purchased shares of publicly held companies and are included in prepaid expenses and other in Cadence’s consolidated balance sheets. Changes in the fair value of these investments are recorded to other income (expense), net in Cadence’s consolidated income statements. The carrying value of marketable equity investments was $80.6 million and $4.5 million as of December 31, 2023, and December 31, 2022, respectively. Marketable Debt Securities The following is a summary of Cadence’s available-for-sale debt securities recorded within prepaid expenses and other on the consolidated balance sheet as of December 31, 2023: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated (In thousands) Available-for-sale securities Mortgage-backed and asset-backed securities $ 49,653 $ 375 $ (243) $ 49,785 Total available-for-sale securities $ 49,653 $ 375 $ (243) $ 49,785 Gross unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on Cadence's consolidated balance sheets. As of December 31, 2023, the fair values of available-for-sale debt securities, by remaining contractual maturity, were as follows: (In thousands) Due within 1 year $ — Due after 1 year through 5 years 10,027 Due after 5 years through 10 years 16,180 Due after 10 years 23,578 Total $ 49,785 As of December 31, 2023, Cadence does not intend to sell any of its available-for-sale securities in an unrealized loss position, and it is more likely than not that Cadence will hold the securities until maturity or a recovery of the cost basis. Non-Marketable Equity Investments Cadence’s investments in non-marketable equity securities generally consist of stock or other instruments of privately held entities and are included in other assets on Cadence’s consolidated balance sheets. Cadence holds a 16% interest in a privately held company that is accounted for using the equity method of accounting. The carrying value of this investment was $111.1 million and $117.7 million as of December 31, 2023, and December 31, 2022, respectively. Cadence records its proportionate share of net income from the investee, offset by amortization of basis differences, to other income (expense), net in Cadence’s consolidated income statements. During fiscal 2023, 2022 and 2021, Cadence recorded losses of $2.7 million, $3.6 million and $1.1 million respectively. Cadence also holds other non-marketable investments in privately held companies where Cadence does not have the ability to exercise significant influence and the fair value of the investments is not readily determinable. The carrying value of these investments was $27.2 million and $2.3 million as of December 31, 2023, and December 31, 2022, respectively. There were no material upward or downward adjustments to non-marketable investments held or sold by Cadence during the periods presented.

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets; • Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the fiscal years presented. On a quarterly basis, Cadence measures at fair value certain financial assets and liabilities. The fair value of financial assets and liabilities was determined using the following levels of inputs as of December 31, 2023, and December 31, 2022: Fair Value Measurements as of December 31, 2023 Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 490,983 $ 490,983 $ — $ — Marketable equity securities: Marketable equity securities 80,575 80,575 — — Mortgage-backed and asset-backed securities 49,785 — 49,785 — Securities held in NQDC trust 75,671 75,671 — — Foreign currency exchange contracts 9,327 — 9,327 — Total Assets $ 706,341 $ 647,229 $ 59,112 $ — As of December 31, 2023, Cadence did not have any financial liabilities requiring a recurring fair value measurement. Fair Value Measurements as of December 31, 2022: Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 548,373 $ 548,373 $ — $ — Marketable equity securities 4,490 4,490 — — Securities held in NQDC trust 55,605 55,605 — — Foreign currency exchange contracts 5,306 — 5,306 — Total Assets $ 613,774 $ 608,468 $ 5,306 $ — As of December 31, 2022, Cadence did not have any financial liabilities requiring a recurring fair value measurement. Level 1 Measurements Cadence’s cash equivalents held in money market funds, marketable equity securities and the trading securities held in Cadence’s NQDC trust are measured at fair value using Level 1 inputs. Level 2 Measurements The valuation techniques used to determine the fair value of Cadence’s investments in marketable debt securities, foreign currency forward exchange contracts, the 2024 Notes and the 2025 Term Loan are classified within Level 2 of the fair value hierarchy. For additional information relating to Cadence’s debt arrangements, see Note 5 in the notes to consolidated financial statements. Level 3 Measurements During fiscal 2023, Cadence acquired intangible assets of $41.0 million. The fair value of the intangible assets acquired was determined using variations of the income approach that utilizes unobservable inputs classified as Level 3 measurements. For existing technology, the fair value was determined by applying the relief-from-royalty method. This method is based on the application of a royalty rate to forecasted revenue to quantify the benefit of owning the intangible asset rather than paying a royalty for use of the asset. To estimate royalty savings over time, Cadence projected revenue from the acquired existing technology over the estimated remaining life of the technology, including the effect of assumed technological obsolescence, before applying an assumed royalty rate. Cadence assumed technological obsolescence at rates between 10% and 13% annually, before applying an assumed royalty rate between 25% and 30%. For agreements and relationships, the fair value was determined by using the multi-period excess earnings method. This method reflects the present value of the projected cash flows that are expected to be generated from existing customers, less charges representing the contribution of other assets to those cash flows. Projected income from existing customer relationships was determined using customer retention rates between 70% and 90%. The present value of operating cash flows from existing customers was determined using discount rates between 12% and 15%. During fiscal 2022, Cadence acquired intangible assets of $178.6 million. The fair value of the intangible assets acquired was determined using variations of the income approach that utilizes unobservable inputs classified as Level 3 measurements. With its acquisitions of OpenEye and Future Facilities, Cadence acquired combined intangible assets of $155.5 million. For existing technology acquired with OpenEye and Future Facilities, the fair value was determined by applying the relief-from-royalty method. This method is based on the application of a royalty rate to forecasted revenue to quantify the benefit of owning the intangible asset rather than paying a royalty for use of the asset. To estimate royalty savings over time, Cadence projected revenue from the acquired existing technology over the estimated remaining life of the technology, including the effect of assumed technological obsolescence, before applying an assumed royalty rate. For both OpenEye and Future Facilities, Cadence assumed technological obsolescence at a rate of 10% annually, before applying an assumed royalty rate of 25%. The fair value for agreements and relationships acquired with its acquisitions of OpenEye and Future Facilities was determined by using the multi-period excess earnings method. This method reflects the present value of the projected cash flows that are expected to be generated from existing customers, less charges representing the contribution of other assets to those cash flows. Projected income from existing customer relationships was determined using customer retention rates between 95% and 100% for OpenEye and 95% for Future Facilities. The present value of operating cash flows from existing customers was determined using discount rates ranging from 10% to 11%. Cadence also completed three other business combinations during fiscal 2022, with combined intangible assets of $23.1 million. The fair value of certain intangible assets acquired was determined using the multi-period excess earnings method, a variation of the income approach that utilizes unobservable inputs classified as Level 3 measurements. This method estimates the revenue and cash flows derived from the acquired assets, net of investment in supporting assets. The resulting cash flow, which is attributable solely to the assets acquired, is then discounted at a rate of return commensurate with the associated risk of the asset to calculate the present value. Cadence assumed discount rates ranging from 11.5% to 24.5%. The fair value of the remaining intangible assets acquired was determined using the relief-from-royalty method using a technological obsolescence rate of approximately 12% annually, before applying a royalty rate of 25%. Cadence believes that its estimates and assumptions related to the fair value of its acquired intangible assets and assumed liabilities are reasonable, but significant judgment is involved.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Purchase Obligations Cadence had purchase obligations of $107.4 million as of December 31, 2023, that were associated with agreements or commitments for purchases of goods or services. Cadence expects to settle $68.7 million of these obligations within the next 12 months. Legal Proceedings From time to time, Cadence is involved in various disputes and litigation that arise in the ordinary course of business. These include disputes and legal proceedings related to IP, indemnification obligations, mergers and acquisitions, licensing, contracts, customers, products, distribution and other commercial arrangements and employee relations matters. Cadence is also subject from time to time to inquiries, investigations and regulatory proceedings involving governments and regulatory agencies in the jurisdictions in which Cadence operates. At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates. Tax Proceedings In December 2022, Cadence received a tax audit assessment of approximately $49 million from the Korea taxing authorities for years 2017-2019. The tax audit assessment is primarily related to value-added taxes. Cadence was required to pay these assessed taxes, prior to being allowed to contest or litigate the assessment in administrative and judicial proceedings. The assessment was paid by Cadence in January 2023 and recorded as a component of other assets in the consolidated balance sheets. Payment of this amount is not an admission that Cadence is subject to such taxes, and Cadence continues to defend its position vigorously. Cadence did not record a reserve for this contingency as of December 31, 2023 or December 31, 2022 as Cadence does not believe a loss is probable because it believes it will ultimately prevail in full. The entire dispute resolution process may take up to eight years. Other Contingencies Cadence provides its customers with a warranty on sales of hardware products, generally for a 90-day period. Cadence did not incur any significant costs related to warranty obligations during fiscal 2023, 2022 or 2021. Cadence’s product license and services agreements typically include a limited indemnification provision for claims from third parties relating to Cadence’s IP. If the potential loss from any indemnification claim is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. In connection with a litigation campaign launched in April 2022 by Bell Semiconductor LLC (“Bell Semi”), a patent monetization entity, some customers sought defense and indemnification against claims of patent infringement asserted by Bell Semi in various district court litigation and at the U.S. International Trade Commission. Bell Semi alleged that the customers’ use of one or more features of certain Cadence products infringed one or more of six patents held by Bell Semi. Cadence offered to defend some of its customers consistent with the terms of the applicable license agreements. On July 25, 2023, Cadence and Bell Semi reached a settlement agreement involving the six patents-in-suit. The settlement amount was not material to Cadence. Cadence did not incur any material losses from indemnification claims during fiscal 2023, 2022 or 2021.

Retirement Benefits [Abstract]
EMPLOYEE AND DIRECTOR BENEFIT PLANS	EMPLOYEE AND DIRECTOR BENEFIT PLANS Cadence maintains various defined contribution plans for its eligible U.S. and non-U.S. employees. For employees in the United States, Cadence maintains a 401(k) savings plan to provide retirement benefits through tax-deferred salary deductions and may make discretionary contributions, as determined by the Board of Directors, which cannot exceed a specified percentage of the annual aggregate salaries of those employees eligible to participate. Cadence’s total contributions made to these plans during fiscal 2023, 2022 and 2021 were as follows: 2023 2022 2021 (In thousands) Contributions to defined contribution plans $ 39,651 $ 35,464 $ 33,029 Executive Officers and Directors may also elect to defer compensation payable to them under Cadence’s NQDC. Deferred compensation payments are held in investment accounts and the values of the accounts are adjusted each quarter based on the fair value of the investments held in the NQDC. These investments are classified in other assets in the consolidated balance sheets and gains and losses are recognized as other income (expense), net in the consolidated income statements. Certain of Cadence’s international subsidiaries sponsor defined benefit retirement plans. The unfunded projected benefit obligation for Cadence’s defined benefit retirement plans is recorded in other long-term liabilities in the consolidated balance sheets.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING Segment reporting is based on the “management approach,” following the method that management organizes the company’s reportable segments for which separate financial information is made available to, and evaluated regularly by, the chief operating decision maker in allocating resources and in assessing performance. Cadence’s chief operating decision maker is its CEO, who reviews Cadence’s consolidated results as one operating segment. In making operating decisions, the CEO primarily considers consolidated financial information, accompanied by disaggregated information about revenues by geographic region. Outside the United States, Cadence markets and supports its products and services primarily through its subsidiaries. Revenue is attributed to geography based upon the country in which the product is used, or services are delivered. Long-lived assets are attributed to geography based on the country where the assets are located. The following table presents a summary of revenue by geography for fiscal 2023, 2022 and 2021: 2023 2022 2021 (In thousands) Americas: United States $ 1,694,529 $ 1,577,881 $ 1,292,980 Other Americas 65,259 53,123 42,141 Total Americas 1,759,788 1,631,004 1,335,121 Asia: China 679,538 521,509 378,160 Other Asia 766,409 629,533 566,772 Total Asia 1,445,947 1,151,042 944,932 Europe, Middle East and Africa 655,078 582,350 523,390 Japan 229,173 197,322 184,801 Total $ 4,089,986 $ 3,561,718 $ 2,988,244 The following table presents a summary of long-lived assets by geography as of December 31, 2023, December 31, 2022, and January 1, 2022: As of December 31, December 31, January 1, (In thousands) Americas: United States $ 383,807 $ 347,822 $ 267,202 Other Americas 10,219 7,548 975 Total Americas 394,026 355,370 268,177 Asia: China 29,598 51,667 56,403 Other Asia 71,365 73,329 54,677 Total Asia 100,963 124,996 111,080 Europe, Middle East and Africa 56,449 56,959 53,748 Japan 2,572 4,505 3,030 Total $ 554,010 $ 541,830 $ 436,035

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	The consolidated financial statements include the accounts of Cadence and its subsidiaries after elimination of intercompany accounts and transactions. All consolidated subsidiaries are wholly owned by Cadence. Historically, Cadence’s fiscal years were 52- or 53-week periods ending on the Saturday closest to December 31. During fiscal 2022, Cadence’s Board of Directors approved a change in its fiscal year end from the Saturday closest to December 31 of each year to December 31 of each year. The fiscal year change became effective beginning with Cadence’s 2023 fiscal year, which began on January 1, 2023. Both fiscal year 2022 and 2021, which are included in this report for comparative purposes, represent 52-week periods. Cadence’s first three fiscal quarters end on March 31, June 30, and September 30. No transition report was required in connection with this change.
Use of Estimates	Preparation of the consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Cadence has not recently adopted any accounting standard updates that are material or potentially material to its consolidated financial statements. New Accounting Standards Not Yet Adopted Segment Reporting In November 2023. the Financial Accounting Standards Board (“FASB”), issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” intended to improve reportable segment disclosure requirements, primarily through enhanced annual and interim disclosures about significant segment expenses. This standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. Cadence is currently evaluating the impact of this standard on its financial statement disclosures. Income Taxes
Foreign Operations	Cadence transacts business in various foreign currencies. The United States dollar is the functional currency of Cadence’s consolidated entities operating in the United States and certain of its consolidated subsidiaries operating outside the United States. The functional currency for Cadence’s other consolidated entities operating outside of the United States is generally the country’s local currency.
Concentrations of Credit Risk	Financial instruments, including derivative financial instruments, that may potentially subject Cadence to concentrations of credit risk, consist principally of cash and cash equivalents, accounts receivable, investments and forward contracts. Credit exposure related to Cadence’s foreign currency forward contracts is limited to the realized and unrealized gains on these contracts.
Cash and Cash Equivalents	Cadence considers all highly liquid investments with original maturities of three months or less on the date of purchase to be cash equivalents.
Receivables	Cadence’s receivables, net includes invoiced accounts receivable and the current portion of unbilled receivables. Unbilled receivables represent amounts Cadence has recorded as revenue for which payments from a customer are due over time and Cadence has an unconditional right to the payment. Cadence’s accounts receivable and unbilled receivables were initially recorded at the transaction value. Cadence’s long-term receivables balance includes receivable balances to be invoiced more than one year after each balance sheet date.
Allowance for Doubtful Accounts	Cadence assesses its ability to collect outstanding receivables and provides customer-specific allowances, allowances for credit losses and general allowances for the portion of its receivables that are estimated to be uncollectible. The allowances are based on the current creditworthiness of its customers, historical experience, expected credit losses, changes in customer demand and the overall economic climate in the industries that Cadence serves. Provisions for these allowances are recorded in general and administrative expense in Cadence’s consolidated income statements.
Inventories	Inventories are computed at standard costs which approximate actual costs and are valued at the lower of cost or net realizable value based on the first-in, first-out method. Cadence’s inventories include high technology parts and components for complex emulation and prototyping hardware systems. These parts and components are specialized in nature and may be subject to rapid technological obsolescence. While Cadence has programs to manage the required inventories on hand and considers technological obsolescence when estimating required reserves to reduce recorded amounts to market values, it is reasonably possible that such estimates could change in the near term.
Inventory Impairment	Cadence’s policy is to reserve for inventory in excess of 12-month demand or for other known obsolescence or realization issues.
Property, Plant and Equipment	Property, plant and equipment is stated at historical cost. Depreciation and amortization are generally provided over the estimated useful lives, using the straight-line method, as follows: Equipment and internal-use software 2-7 years Buildings 25-32 years Leasehold improvements Shorter of the lease term or the estimated useful life Building improvements and land improvements Up to 32 years Furniture and fixtures 3-5 years
Software Development Costs	Software development costs are capitalized beginning when a product’s technological feasibility has been established by completion of a working model of the product and amortization begins when a product is available for general release to customers. The period between the achievement of technological feasibility and the general release of Cadence’s products has typically been of short duration. Costs incurred during fiscal 2023, 2022 and 2021 were not material.
Deferred Sales Commisions	Cadence records an asset for the incremental costs of obtaining a contract with a customer, including direct sales commissions that are earned upon execution of the contract. Cadence uses the portfolio method to recognize the amortization expense related to these capitalized costs related to initial contracts and renewals and such expense is recognized over a period associated with the revenue of the related portfolio, which is generally two to three years for Cadence’s software arrangements and upon delivery for its hardware and IP arrangements. Incremental costs related to initial contracts and renewals are amortized over the period of the arrangement in each case because Cadence pays the same commission rate for both new contracts and renewals. Deferred sales commissions are tested for impairment on an ongoing basis when events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment is recognized to the extent that the amount of deferred sales commission exceeds the remaining expected gross margin (remaining revenue less remaining direct costs) on the goods and services to which the deferred sales commission relates. Total capitalized costs were $47.6 million and $41.7 million as of December 31, 2023, and December 31, 2022, respectively, and are included in other assets in Cadence’s consolidated balance sheet. Amortization of these assets was $41.4 million, $40.5 million and $40.1 million during fiscal 2023, 2022 and 2021, respectively, and is included in sales and marketing expense in Cadence’s consolidated income statement.
Goodwill	Cadence conducts a goodwill impairment analysis annually and as necessary if changes in facts and circumstances indicate that the fair value of Cadence’s single reporting unit may be less than its carrying amount. To assess for impairment, Cadence compares the estimated fair value of its single reporting unit to the carrying value of the reporting unit’s net assets, including goodwill. If the fair value of the reporting unit is greater than the carrying value of its net assets, goodwill is not considered to be impaired, and no further analysis is required. If the fair value of the reporting unit is less than the carrying value of its net assets, Cadence would be required to record an impairment charge.
Long-lived Assets, Including Acquired Intangibles	Cadence’s long-lived assets consist of property, plant and equipment, and acquired intangibles. Acquired intangibles consist of acquired technology, certain contract rights, customer relationships, trademarks and trade names, capitalized software, and in-process research and development. These acquired intangibles are acquired through business combinations or direct purchases. Acquired intangibles with definite lives are amortized on a straight-line basis over the estimated economic life of the underlying products and technologies, which range from three years to fifteen years. Acquired intangibles with indefinite lives, or in-process technology, consists of projects that had not reached technological feasibility by the date of acquisition. Upon completion of the project, the assets are amortized over their estimated useful lives. If the project is abandoned rather than completed, the asset is written off. In-process technology is tested for impairment annually and as necessary if changes in facts and circumstances indicate that the assets might be impaired. Cadence reviews its long-lived assets, including acquired intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset or asset group may not be recoverable. Recoverability of an asset or asset group is measured by comparison of its carrying amount to the expected future undiscounted cash flows that the asset or asset group is expected to generate. If it is determined that the carrying amount of an asset group is not recoverable, an impairment loss is recorded in the amount by which the carrying amount of the asset or asset group exceeds its fair value.
Lessee Considerations	Lessee Considerations Cadence has operating leases primarily consisting of facilities with remaining lease terms of approximately one year to fifteen years. Cadence has options to terminate many of its leases early. The lease term represents the period up to the early termination date unless it is reasonably certain that Cadence will not exercise the early termination option. For certain leases, Cadence has options to extend the lease term for additional periods ranging from one year to ten years. Renewal options are not considered in the remaining lease term unless it is reasonably certain that Cadence will exercise such options. At inception of a contract, Cadence determines an arrangement contains a lease if the arrangement conveys the right to use an identified asset and Cadence obtains substantially all of the economic benefits from the asset and has the ability to direct the use of the asset. Leases with an initial term of twelve months or less are not recorded on the balance sheet. For lease agreements entered into or reassessed after the adoption of Topic 842, Cadence combines the lease and non-lease components in determining the lease liabilities and right-of-use (“ROU”) assets. Non-lease components primarily include common-area maintenance and other management fees. Operating lease expense is generally recognized evenly over the term of the lease. Payments under Cadence's lease agreements are primarily fixed; however, certain agreements contain rental payments that are adjusted periodically based on changes in consumer price and other indices. Changes to payments resulting from changes in indices are expensed as incurred and not included in the measurement of lease liabilities and ROU assets. Cadence’s lease agreements do not provide an implicit borrowing rate, therefore an internal incremental borrowing rate is determined based on information available at lease commencement date for purposes of determining the present value of lease payments. The incremental borrowing rate represents a comparable rate to borrow on a collateralized basis over a similar term and in the economic environment where the leased asset is located.
Lessor Considerations	Lessor Considerations Although most of Cadence’s revenue from its hardware business comes from sales of hardware, Cadence also leases its hardware products to some customers. Cadence determines the existence of a lease when the customer controls the use of the identified hardware for a period of time defined in the lease agreement. Cadence’s leases range in duration up to three years with payments generally collected in equal quarterly installments. Cadence’s leases do not include termination rights or variable pricing and typically do not include purchase rights at the end of the lease. Short-term leases are usually less than two years and are classified as operating leases with revenue recognized and depreciation expensed on a straight-line basis over the term of the lease. Long-term leases are typically for three years and are classified as sales-type leases with revenue and cost of sales recognized upon installation.
Investments in Equity Securities	Cadence’s investments in marketable equity securities are carried at fair value as a component of prepaid expenses and other in the consolidated balance sheets. Cadence records realized and unrealized holding gains or losses as part of other income (expense), net in the consolidated income statements. Cadence’s non-marketable investments include its investments in privately held companies. These investments are initially recorded at cost and are included in other assets in the consolidated balance sheets. Cadence accounts for these investments using the measurement alternative when the fair value of the investment is not readily determinable, and Cadence does not have the ability to exercise significant influence, or the equity method of accounting when it is determined that Cadence has the ability to exercise significant influence. For investments accounted for using the equity method of accounting, Cadence records its proportionate share of the investee’s income or loss, net of the effects of any basis differences, to other income (expense), net on a one-quarter lag in Cadence’s consolidated income statements.
Investments in Debt Securities	Cadence’s investments in debt securities are comprised of investments in mortgage-backed and asset backed-securities and are carried at fair value as a component of prepaid expenses and other in the consolidated balance sheets. Cadence classifies its investment in debt securities as available-for-sale, and gross unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on its consolidated balance sheets. Cadence assesses its portfolio of debt securities for impairment at least quarterly. Cadence records an allowance for credit losses on debt securities when the fair value of a debt security is below its amortized cost, and it is more likely than not that Cadence will either sell the impaired security before recovery of its amortized basis or has the intention to sell the security. Provisions for credit losses on impaired debt securities are recorded as a component of other income (expense), net in the consolidated income statements.
Derivative Financial Instruments	Cadence enters into foreign currency forward exchange contracts with financial institutions to protect against currency exchange risks associated with existing assets and liabilities. A foreign currency forward exchange contract acts as a hedge by increasing in value when underlying assets decrease in value or underlying liabilities increase in value due to changes in foreign exchange rates. Conversely, a foreign currency forward exchange contract decreases in value when underlying assets increase in value or underlying liabilities decrease in value due to changes in foreign exchange rates. The forward contracts are not designated as accounting hedges and, therefore, the unrealized gains and losses are recognized in other income (expense), net, in advance of the actual foreign currency cash flows. The fair value of these forward contracts is recorded in accrued liabilities or in other current assets. These forward contracts generally have maturities of 90 days or less.
Nonqualified Deferred Compensation Trust	Executive officers, senior management and members of Cadence’s Board of Directors may elect to defer compensation payable to them under Cadence’s Nonqualified Deferred Compensation Plan (“NQDC”). Deferred compensation payments are held in investment accounts and the values of the accounts are adjusted each quarter based on the fair value of the investments held in the NQDC. The selected investments held in the NQDC accounts are carried at fair value, with the unrealized gains and losses recognized in the consolidated income statements as other income (expense), net. These securities are classified in other assets in the consolidated balance sheets because they are not available for Cadence’s use in its operations. Cadence’s obligation with respect to the NQDC trust is recorded in other long-term liabilities on the consolidated balance sheets. Increases and decreases in the NQDC trust liability are recorded as compensation expense in the consolidated income statements.
Treasury Stock	Cadence generally issues shares related to its stock-based compensation plans from shares held in treasury. When treasury stock is reissued at an amount higher than its cost, the difference is recorded as a component of capital in excess of par in the consolidated statements of stockholders’ equity. When treasury stock is reissued at an amount lower than its cost, the difference is recorded as a component of capital in excess of par to the extent that gains exist to offset the losses. If there are no accumulated treasury stock gains in capital in excess of par, the losses upon reissuance of treasury stock are recorded as a component of retained earnings in the consolidated statements of stockholders’ equity. There were no losses recorded as a component of retained earnings by Cadence on the reissuance of treasury stock during fiscal 2023, 2022 or 2021. The Inflation Reduction Act of 2022, which was enacted into law on August 16, 2022, imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. During fiscal 2023, Cadence recorded excise tax of $0.9 million as a component of treasury stock to account for the incremental cost of the shares repurchased. A corresponding liability for the excise tax payable was recorded as a component of accounts payable and accrued liabilities on Cadence's consolidated balance sheet as of December 31, 2023.
Revenue Recognition	Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which Cadence expects to be entitled in exchange for promised goods or services. Cadence’s performance obligations are satisfied either over time or at a point in time. Product and maintenance revenue includes Cadence’s licenses of software and IP, sales of emulation hardware and the related maintenance on these licenses and sales. Services revenue includes revenue received for performing engineering services (which are generally not related to the functionality of other licensed products), customized IP on a fixed fee basis, and sales from cloud-based solutions that provide customers with software, hardware and services over a period of time. Cadence enters into contracts that can include various combinations of licenses, products and services, some of which are distinct and are accounted for as separate performance obligations. For contracts with multiple performance obligations, Cadence allocates the transaction price of the contract to each performance obligation, generally on a relative basis using its SSP. Cadence generates revenue from contracts with customers and applies judgment in identifying and evaluating any terms and conditions in contracts which may impact revenue recognition. Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities. Some customers enter into non-cancelable commitments whereby the customer commits to a fixed dollar amount over a specified period of time that can be used to purchase from a list of products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate selection form to identify the products and services that they are purchasing. Each separate selection form under the arrangement is treated as an individual contract and accounted for based on the respective performance obligations. Cadence records a customer deposit liability for amounts received from customers prior to the arrangement meeting the definition of a revenue contract. Software Revenue Recognition Cadence’s time-based license arrangements grant customers the right to access and use all of the licensed products at the outset of an arrangement and updates are generally made available throughout the entire term of the arrangement, which is generally two to three years. Cadence’s updates provide continued access to evolving technology as customers’ designs migrate to more advanced nodes and as its customers’ technological requirements evolve. In addition, certain time-based license arrangements include remix rights and unspecified additional products that become commercially available during the term of the agreement. Payments are generally received in equal or near equal installments over the term of the agreement. Multiple software licenses, related updates, and technical support in these time-based arrangements constitute a single, combined performance obligation and revenue is recognized over the term of the license, commencing upon the later of the effective date of the arrangement or transfer of the software license. Remix rights are not an additional promised good or service in the contract, and where unspecified additional software product rights are part of the contract with the customer, such rights are accounted for as part of the single performance obligation that includes the licenses, updates, and technical support because such rights are provided for the same period of time and have the same time-based pattern of transfer to the customer. Hardware Revenue Recognition Cadence generally has two performance obligations in arrangements involving the sale or lease of hardware products. The first performance obligation is to transfer the hardware product (which includes software integral to the functionality of the hardware product). The second performance obligation is to provide maintenance on hardware and its embedded software, which includes rights to technical support, hardware repairs and software updates that are all provided over the same term and have the same time-based pattern of transfer to the customer. The transaction price allocated to the hardware product is generally recognized as revenue at the time of delivery because the customer obtains control of the product at that point in time. Cadence has concluded that control generally transfers at that point in time because the customer has title to the hardware, physical possession, and a present obligation to pay for the hardware. The transaction price allocated to maintenance is recognized as revenue ratably over the maintenance term. Payments for hardware contracts are generally received upon delivery of the hardware product. Shipping and handling costs are considered fulfillment costs and are included in cost of product and maintenance in Cadence’s consolidated income statements. IP Revenue Recognition Cadence generally licenses IP under nonexclusive license agreements that provide usage rights for specific designs. In addition, for certain of Cadence’s IP license agreements, royalties are collected as customers ship their own products that incorporate Cadence IP. These arrangements generally have two performance obligations—transferring the licensed IP and associated maintenance, which includes rights to technical support, and software updates that are all provided over the maintenance term and have a time-based pattern of transfer to the customer. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery of the IP or the beginning of the license period and revenue allocated to the maintenance is recognized over the maintenance term. Royalties are recognized as revenue in the quarter in which the applicable Cadence customer ships its products that incorporate Cadence IP. Payments for IP contracts are generally received upon delivery of the IP. Cadence customizes certain IP and revenue related to this customization is recognized as services revenue as described below. Services Revenue Recognition Revenue from service contracts is recognized over time, generally using costs incurred or hours expended to measure progress. Cadence has a history of accurately estimating project status and the costs necessary to complete projects. A number of internal and external factors can affect these estimates, including labor rates, utilization and efficiency variances and specification and testing requirement changes. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources.
Stock-Based Compensation	Cadence recognizes the cost of awards of equity instruments granted to employees in exchange for their services as stock-based compensation expense. Stock-based compensation expense is measured at the grant date based on the value of the award and is recognized as expense over the requisite service period, which is typically the vesting period. Cadence recognizes stock-based compensation expense on the straight-line method for awards that only contain a service condition and on the graded-vesting method for awards that contain both a service and performance condition. Cadence recognizes the impact of forfeitures on stock-based compensation expense as they occur. The fair value of stock options and purchase rights issued under Cadence’s Employee Stock Purchase Plan (“ESPP”) are calculated using the Black-Scholes option pricing model. The computation of the expected volatility assumption used for new awards is based on a weighting of historical and implied volatilities. When determining the expected term, Cadence reviews historical employee exercise behavior from options having similar vesting periods. The risk-free interest rate for the period within the expected term of the option is based on the yield of United States Treasury notes for the comparable term in effect at the time of grant. The expected dividend yield used in the calculation is zero because Cadence has not historically paid and currently does not expect to pay dividends in the foreseeable future. The fair value of market-based performance stock awards is calculated using a Monte Carlo simulation model and takes into account the same input assumptions as the Black-Scholes model, as well as the possibility that the market conditions may not be satisfied. Cadence recognizes stock-based compensation expense on the graded-vesting method for market-based performance stock awards.
Advertising	Cadence expenses the costs of advertising as incurred. Total advertising expense, including marketing programs and events, was $21.7 million, $17.0 million and $7.5 million during fiscal 2023, 2022 and 2021, respectively, and is included in marketing and sales in the consolidated income statements.
Restructuring	Cadence records personnel-related restructuring charges with termination benefits when the costs are both probable and estimable. Cadence records personnel-related restructuring charges with non-customary termination benefits when the plan has been communicated to the affected employees. Cadence generally begins recording facilities-related restructuring charges in the period in which a formal plan to vacate an affected facility is established. In connection with facilities-related restructuring plans, Cadence has made certain assumptions and estimates related to facilities, particularly the timing of exit and the ability to sublease. Facility closure costs in restructuring charges primarily includes accelerated ROU asset amortization, lease buyout costs and certain contractual costs to maintain facilities during the period after abandonment. Cadence records estimated provisions for termination benefits and outplacement costs along with other personnel-related restructuring costs, asset impairments related to abandoned assets and other costs associated with the restructuring plan. Cadence regularly evaluates the adequacy of its restructuring liabilities and adjusts the balances based on actual costs incurred or changes in estimates and assumptions. Subsequent adjustments to restructuring accruals are classified as restructuring in the consolidated income statements.
Accounting for Income Taxes	Cadence accounts for the effect of income taxes in its consolidated financial statements using the asset and liability method. This process involves estimating actual current tax liabilities together with assessing carryforwards and temporary differences resulting from differing treatment of items, such as depreciation, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, measured using enacted tax rates expected to apply to taxable income in the years when those temporary differences are expected to be recovered or settled. Cadence accounts for the United States global intangible low-taxed income as a period expense. Cadence then records a valuation allowance to reduce the deferred tax assets to the amount that Cadence believes is more likely than not to be realized based on its judgment of all available positive and negative evidence. The weight given to the potential effect of negative and positive evidence is commensurate with the extent to which the strength of the evidence can be objectively verified. This assessment, which is completed on a taxing jurisdiction basis, takes into account a number of types of evidence, including the following: • the nature and history of current or cumulative financial reporting income or losses; • sources of future taxable income; • the anticipated reversal or expiration dates of the deferred tax assets; and • tax planning strategies. Cadence takes a two-step approach to recognizing and measuring the financial statement benefit of uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement of the audit. Cadence classifies interest and penalties on unrecognized tax benefits as income tax expense or benefit.
Fair Value of Financial Instruments	Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets; • Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
Commitments and Contingencies	Cadence is also subject from time to time to inquiries, investigations and regulatory proceedings involving governments and regulatory agencies in the jurisdictions in which Cadence operates. At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates.
