Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation. Our fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, we have a 53-week year. When a 53-week year occurs, we include the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2022, 2021 and 2020 were 52-week years ending on October 29, 2022, October 30, 2021 and October 31, 2020, respectively. For presentation purposes, the consolidated financial statements and accompanying notes refer to the closest calendar month end. Fiscal 2023 will be a 52-week year. The consolidated financial statements include our accounts and the accounts of our wholly and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates. To prepare financial statements in conformity with U.S. generally accepted accounting principles, management must make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and could have a material impact on our operating results and financial position. Comparability. Effective beginning of fiscal 2022, we adopted an Accounting Standards Update (ASU) to simplify the accounting for income taxes in Accounting Standards Codification (ASC) 740, Income Taxes, on a prospective basis. Effective beginning the second quarter of fiscal 2022, we early adopted an ASU, on a prospective basis, to apply revenue guidance to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination on the acquisition date, instead of measuring them at fair value. The adoption of these updates did not have a material impact on our consolidated financial statements. Effective beginning of fiscal 2021, we adopted ASC 326, Measurement of Credit Losses on Financial Instruments. Prior periods were not retrospectively recast and accordingly, the consolidated statements of income for the year ended October 31, 2020 were prepared using accounting standards that were different than those in effect for the years ended October 31, 2022 and 2021. Certain reclassifications have been made to the prior year's consolidated financial statements to conform to the current year presentation. The reclassifications did not have a material impact on the prior year's consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows. Cash and Cash Equivalents and Short-term Investments . We classify investments with original maturities of three months or less when acquired as cash equivalents. Our investments in debt securities with maturities of longer than three months from the consolidated balance sheets date are classified as short-term investments as we may convert these investments into cash at any time to fund general operations. Our debt securities generally have an effective maturity term of less than three years and are classified as available-for-sale securities carried at fair value, with unrealized gains and losses included in the consolidated balance sheets as a component of accumulated other comprehensive income (loss). For available-for-sale debt securities in an unrealized loss position, we evaluate whether a current expected credit loss exists based on available information relevant to the credit rating of the security, current economic conditions and reasonable and supportable forecasts. The allowance for credit loss is recorded in other income (expense), net, on the consolidated statements of income, not to exceed the amount of the unrealized loss. Any excess unrealized loss other than the credit loss is recognized in accumulated other comprehensive income or loss in the stockholders' equity section of the consolidated balance sheets. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net. See Note 7. Financial Assets and Liabilitie s. There were no credit losses on available-for-sale debt securities recognized in the years ended October 31, 2022 and 2021. Accounts Receivable, Net. The balances consist of billed accounts receivable and current portion of unbilled accounts receivable. Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Allowance for Credit Losses. We maintain an allowance for credit losses for expected uncollectible accounts receivable and contract assets, which is recorded as an offset to accounts receivable or contract assets and provisions for credit losses are recorded in general and administrative expense in the consolidated statements of income. The allowance for current expected credit losses is based on a review of customer accounts and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance. The following table presented the changes in the allowance for credit losses: Fiscal Year Balance at Provisions Write-offs/Adjustments Balance at (in thousands) 2022 $ 31,605 $ 12,424 $ (2,793) $ 41,236 2021 $ 29,489 $ 18,515 $ (16,399) $ 31,605 2020 $ 9,971 $ 20,875 $ (1,357) $ 29,489 Inventories. Inventories are computed at standard costs which approximate actual costs, on a first-in, first-out basis and valued at the lower of cost or net realizable value. Inventories primarily include components and finished goods for complex emulation and prototyping hardware systems. The valuation process includes a review of the forecasts based upon future demand and market conditions. Inventory provisions are recorded when the costs are determined to be in excess of anticipated demand or considered obsolete. Inventory provisions are impacted by market and economic conditions, technology changes, new product introductions and changes in strategic direction, and require estimates that may include uncertain elements. Fair Values of Financial Instruments. Our cash equivalents, short-term investments and foreign currency contracts are carried at fair value. The fair value of our accounts receivable and accounts payable approximates the carrying amount due to their short duration. Non-marketable equity securities are accounted for using either the measurement alternative or equity method of accounting, net of impairments. We perform periodic impairment analysis on these non-marketable equity securities. The carrying amount of the short-term and long-term debt approximates the estimated fair value. See Note 8. Fair Value Measurements . Foreign Currency Contracts. We operate internationally and are exposed to potentially adverse movements in currency exchange rates. We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions. The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets. The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting. See Note 7. Financial Assets and Liabilities . Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash equivalents, short-term investments, foreign currency contracts, and trade accounts receivable. We maintain cash equivalents primarily in highly rated taxable and tax-exempt money market funds located in the U.S. and in various overseas locations. We sell our products worldwide primarily to customers in the global electronics market. We perform on-going credit evaluations of our customers’ financial condition and do not require collateral. We establish reserves for potential credit losses and such losses have been within management’s expectations and have not been material in any year presented. Income Taxes. We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We account for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. An uncertain tax position is considered effectively settled on completion of an examination by a taxing authority if certain other conditions are satisfied. Property and Equipment. Property and equipment is recorded at cost less accumulated depreciation. Assets, excluding land, are depreciated using the straight-line method over their estimated useful lives. Depreciation expenses were $107.7 million, $119.1 million and $119.1 million in fiscal 2022, 2021 and 2020, respectively. Repair and maintenance costs are expensed as incurred and such costs were $72.9 million, $62.6 million and $62.1 million in fiscal 2022, 2021 and 2020, respectively. The useful lives of depreciable assets are as follows: Useful Life in Years Computer and other equipment 3 - 8 Buildings 30 Furniture and fixtures 5 Leasehold improvements Shorter of the lease term or the estimated useful life Investments in Equity Securities. We hold equity securities in privately held companies for the promotion of business and strategic objectives. These investments are initially recorded at cost and included in other long-term assets in the consolidated balance sheets and are subject to a periodic impairment review. We account for these investments using the measurement alternative when the fair value of the investment is not readily determinable and we do not have the ability to exercise significant influence or using the equity method of accounting when it is determined that we have the ability to exercise significant influence. For investments accounted for using the equity method of accounting, we record our proportionate share of the investee’s income or loss to other income (expense), net, in our consolidated statements of income. Leases . We determine if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to, and the agreement creates enforceable rights and obligations. A contract is or contains a lease when we have the right to control the use of an identified asset for a period of time. The commencement date of the lease is the date that the lessor makes an underlying asset available for use by the lessee. On the commencement date, leases are evaluated for classification and assets and liabilities are recognized based on the present value of lease payments over the lease term. The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The right of use (ROU) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments and any lease incentives. Variable lease payments, consisting primarily of reimbursement of costs incurred by lessors for common area maintenance, real estate taxes and insurance, are not included in the lease liability and are recognized as they are incurred. As most of our leases do not provide an implicit rate, we use the incremental borrowing rate at lease commencement to measure ROU assets and lease liabilities. We use a benchmark senior unsecured yield curve for debt instruments over the similar term, and consider specific credit quality, market conditions, tenor of lease arrangements, and quality of collateral to determine the incremental borrowing rate. Operating lease expense is generally recognized on a straight-line basis over the lease term. We have elected the practical expedient to account for the lease and non-lease components as a single lease component for the majority of our asset classes. For leases with an initial term of one year or less, we have elected not to record the ROU asset or liability. Business Combinations. We allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed based on their acquisition-date fair values with the exception of contract assets and contract liabilities (deferred revenue) which are recognized and measured on the acquisition date in accordance with our “Revenue Recognition” policy. The excess of the fair value of purchase consideration over the fair value of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred. We include the results of operations of the businesses that are acquired from the acquisition date. Goodwill. Goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible and identifiable intangible assets acquired by us. The carrying amount of goodwill at each reporting unit is tested for impairment annually in the fourth fiscal quarter , or more frequently if facts and circumstances warrant a review. Because the fair values of our reporting units have historically exceeded and are expected to continue to significantly exceed the carrying value of our net assets, we perform a qualitative goodwill impairment assessment. A quantitative goodwill impairment assessment is performed if it is determined that it is more likely than not that the fair value of one of our reporting units is lower than the carrying value. When a quantitative goodwill impairment assessment is performed, we use an income approach based on discounted cash flow analysis, a market approach based on market multiples, or a combination of both. If the fair value of a reporting unit is less than its carrying value, a goodwill impairment charge is recorded for the difference. There was no goodwill impairment in fiscal 2022, 2021 and 2020. Intangible Assets. Intangible assets consist of acquired technology, certain contract rights, customer relationships, trademarks and trade names, and capitalized software. These intangible assets are acquired through business combinations, direct purchases, or internally developed capitalized software. Intangible assets are amortized on a straight-line basis over their estimated useful lives which range from one We review the carrying values of long-lived assets including intangible assets whenever events or changes in circumstances indicate that the carrying value may not be fully recoverable. Recoverability of long-lived assets is measured by comparing the carrying value of such asset group to the future undiscounted cash flows that asset group is expected to generate. If the undiscounted future cash flow is less than the carrying amount of the asset group, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the asset group. There were no impairment charges for long-lived assets in fiscal 2022, 2021 and 2020. Redeemable Non-controlling Interest. Non-controlling interest that is not solely redeemable within our control is reported as temporary equity in our consolidated balance sheets. The carrying value of the redeemable non-controlling interest equals the redemption value at the end of each reporting period, after giving effect to the change from the net income (loss) attributable to the redeemable non-controlling interest. We remeasure the redemption value of the non-controlling interest on a quarterly basis and changes in the estimated redemption value are recognized through retained earnings and may also impact the net income or loss attributable to common stockholders of Synopsys if the redemption value falls below a stated threshold. See Note 4. Business Combinations for more information regarding the redeemable non-controlling interests. Revenue Recognition. We recognize revenue for the transfer of services or products to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those services or products. The principle is achieved through the following five-step approach: • Identification of the contract, or contracts, with the customer • Identification of the performance obligation in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, we satisfy a performance obligation Nature of Products and Services We generate revenue from the licensing of our EDA software, IP Blocks, and Software Integrity products, as well as sale of hardware products, and maintenance and services. The various types are set forth below. Electronic Design Automation Software license revenue consists of fees associated with the licensing of our software primarily through Technology Subscription License (TSL) contracts. TSLs are time-based licenses for a finite term and generally provide the customer with limited rights to receive, or to exchange certain quantities of licensed software for, unspecified future technology. The majority of our arrangements are TSLs due to the nature of our business and customer requirements. In addition to the licenses, the arrangements also include: post-contract customer support, which includes providing frequent updates and upgrades to maintain the utility of the software due to rapid changes in technology; other intertwined services such as multiple copies of the tools; assisting our customers in applying our technology in the customers' development environment; and rights to remix licenses for other licenses. Payments are generally received in equal or near equal installments over the term of the arrangement. We have concluded that our software licenses in TSL contracts are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term. Such updates represent inputs to a single, combined performance obligation, commencing upon the later of the arrangement effective date or transfer of control to 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 pattern of transfer to the customer over the duration of the subscription term. IP & System Integration We generally license IP under nonexclusive license agreements that provide usage rights for specific applications. Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. These arrangements generally have two distinct performance obligations that consist of transferring the licensed IP and the post contract support service. Support services consist of a stand-ready obligation to provide technical support and software updates over the support term. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery date or the beginning of the license period, and revenue allocated to support services is recognized ratably over the support term. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP. Software Integrity Products Software Integrity product arrangements provide customers the right to software licenses, software updates and technical support. Under the term of these arrangements, the customer expects to receive integral updates to the software licenses that protect the customer’s software from potential security vulnerabilities. The licenses and software updates together serve to fulfill our commitment to the customer, as they represent inputs to a single, combined performance obligation that commences upon the later of the arrangement effective date or transfer of the software license. Software updates are part of the contract with the customer, and 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 We generally have two performance obligations in arrangements involving the sale of hardware products. The first performance obligation is to transfer the hardware product, which includes embedded software integral to the functionality of the hardware product. The second performance obligation is to provide maintenance on the hardware and our embedded software, including 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 portion of the transaction price allocated to the hardware product is recognized as revenue at a point in time when control of the hardware is transferred to the customer. We have concluded that control generally transfers upon shipment because the customer has the ability to direct the use of the asset and an obligation to pay for the hardware. The portion of the transaction price allocated to maintenance is recognized as revenue that is ratable over the maintenance term. Professional Services Our arrangements often include service elements (other than maintenance and support services). These services include training, design assistance, and consulting. These services are generally performed on a time and materials basis, and are recognized over time, as the customer simultaneously receives and consumes the benefit provided. Certain arrangements also include the customization or modification of licensed IP. Revenue from these contracts is recognized over time as the services are performed, when the development is specific to the customer’s needs and we have enforceable rights to payment for performance completed. Inputs such as costs incurred and hours expended are used in order to measure progress of performance. We have 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, specification and testing requirement changes, and changes in customer delivery priorities. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources. Flexible Spending Accounts Our customers frequently enter into non-cancelable Flexible Spending Account arrangements (FSA) 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 our products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate order (pulldown request) to identify the required products and services that they are purchasing. The combination of the FSA arrangement and the subsequent order creates enforceable rights and obligations, thus meeting the definition of a revenue contract. Each separate order under the agreement is treated as an individual contract and accounted for based on the respective performance obligations included within the pulldown requests. Significant Judgments Our contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether services and products are considered distinct performance obligations that should be accounted for separately versus together requires significant judgment . We have concluded that (1) our EDA software licenses in TSL contracts are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term, because those promises represent inputs to a single, combined performance obligation, and (2) 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. In reaching this conclusion, we considered the nature of the obligation to customers which is to provide an ongoing right to use the most up to date and relevant software. As EDA customers operate in a rapidly changing and competitive environment, satisfying the obligation requires providing critical updates to the existing software products, including ongoing iterative interaction with customers to make the software relevant to customers’ ability to meet the time to go to market with advanced products. Similarly, we also concluded that in our Software Integrity business, the licenses and maintenance updates serve together to fulfill our commitment to the customer as both work together to provide the functionality to the customer and represent a combined performance obligation because the updates are essential to the software’s central utility, which is to identify security vulnerabilities and other threats. Our contracts with customers can involve hundreds of products and various license rights. Customers often negotiate a broad portfolio of solutions, and favorable terms along with future purchase options to manage their overall costs. Determining whether the purchase options are considered distinct performance obligations that should be accounted for separately as material rights versus combined together may require significant judgment. Judgment is also required to determine the standalone selling price (SSP) for each distinct performance obligation. For non-software performance obligations (IP, Hardware, and services), SSP is established based on observable prices of products and services sold separately. SSP for license (and related updates and support) in a contract with multiple performance obligations is determined by applying a residual approach whereby all other non-software performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSP, using observable prices, with any residual amount of the transaction price allocated to the license because we do not sell the license separately, and the pricing is highly variable. Contract Balances The timing of revenue recognition may differ from the timing of invoicing customers, and these timing differences result in receivables (billed or unbilled), contract assets, or contract liabilities (deferred revenue) on our consolidated balance sheet. We record a contract asset when revenue is recognized prior to the right to invoice, or deferred revenue when revenue is recognized subsequent to invoicing. For time-based software agreements, customers are generally invoiced in equal, quarterly amounts, although some customers prefer to be invoiced in single or annual amounts. We record an unbilled receivable when revenue is recognized and we have an unconditional right to invoice and receive payment. Warranties and Indemnities Warranties. We generally warrant our products to be free from defects in media and to substantially conform to material specifications for a period of 90 days for our software products and for up to six months for our hardware products. Indemnities. In addition to such warranties, in certain cases, we provide our customers with limited indemnification with respect to claims that their use of our software products infringes on patents, copyrights, trademarks or trade secrets. For example, in connection with a litigation campaign launched by Bell Semiconductor LLC (Bell Semic), a patent monetization entity, some customers have requested defense and indemnification against claims of patent infringement asserted by Bell Semic in various district court litigations and at the U.S. International Trade Commission. Bell Semic alleges that the customers’ use of one or more features of certain of our products infringes one or more of six patents held by Bell Semic. We have offered to defend some of our customers consistent with the terms of our End User License Agreement. We are unable to estimate the potential impact of these commitments on the future results of operations. Net Income Per Share. We compute basic net income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested restricted stock units and awards during the period using the treasury stock method. See Note 14. Net Income Per Share. Foreign Currency Translation. The functional currency of the majority of our active foreign subsidiaries is the foreign subsidiary’s local currency. Assets and liabilities that are not denominated in the functional currency are remeasured into the functional currency with any related gains or losses recorded in earnings. We translate assets and liabilities of our non-U.S. dollar functional currency foreign operations into the U.S. dollar reporting currency at exchange rates in effect at the balance sheet date. We translate income and expense items of such foreign operations into the U.S. dollar reporting currency at average exchange rates for the period. Accumulated translation adjustments are reported in stockholders’ equity, as a component of accumulated other comprehensive income (loss). Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (FASB) issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. We adopted the standard as of the beginning of fiscal 2022 on a prospective basis and the adoption did not have a material impact on our consolidated financial statements. Beginning in fiscal 2021, we adopted ASC 326, which was issued by the FASB in June 2016 as ASU 2016-13 Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments. The ASU replaced previous incurred loss impairment guidance and established a single expected credit losses allowance framework for financial assets carried at amortized cost. It also eliminated the concept of other-than-temporary impairment and requires credit losses related to certain available-for-sale debt securities to be recorded through an allowance for credit losses. We adopted ASC 326 using the modified retrospective method, which requires a cumulative-effect adjustment to the opening balance of retained earnings to be recognized on the date of adoption and, accordingly, recorded a net decrease of $3.2 million to retained earnings as of beginning of fiscal 2021. Please see the “Allowance for Credit Losses” accounting policy above. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires contract assets and contract liabilitie

Revenue	Revenue Disaggregated Revenue The following table showed the percentage of revenue by product groups: 2022 2021 2020 EDA 50.8 % 55.5 % 57.4 % IP & System Integration 39.3 % 34.8 % 32.6 % Software Integrity Products & Services 9.2 % 9.4 % 9.7 % Other 0.7 % 0.3 % 0.3 % Total 100.0 % 100.0 % 100.0 % Contract Balances The contract assets indicated below are presented as prepaid and other current assets in the consolidated balance sheets. The contract assets are transferred to receivables when the rights to invoice and receive payment become unconditional. Unbilled receivables are presented as accounts receivable, net, in the consolidated balance sheets. Contract balances were as follows: As of October 31, 2022 2021 (in thousands) Contract assets, net $ 260,498 $ 284,574 Unbilled receivables $ 46,254 $ 35,589 Deferred revenue $ 2,065,294 $ 1,653,926 During fiscal 2022, we recognized $1.2 billion of revenue that was included in the deferred revenue balance as of October 31, 2021. During fiscal 2021, we recognized $1.2 billion of revenue that was included in the deferred revenue balance as of October 31, 2020. Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $7.1 billion as of October 31, 2022, which includes $1.1 billion in non-cancellable Flexible Spending Account (FSA) commitments from customers where actual product selection and quantities of specific products or services are to be determined by customers at a later date. We have elected to exclude future sales-based royalty payments from the remaining performance obligations. Approximately 44% of the contracted but unsatisfied or partially unsatisfied performance obligations as of October 31, 2022, excluding non-cancellable FSA, are expected to be recognized over the next 12 months with the remainder recognized thereafter. During fiscal 2022 and fiscal 2021, we recognized $137.3 million and $116.7 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods. Costs of Obtaining a Contract with Customer The incremental costs of obtaining a contract with a customer, which consist primarily of direct sales commission earned upon execution of the contract, were capitalized in compliance with authoritative guidance, and amortized over the estimated period of which the benefit is expected to be received. As direct sales commission paid for renewals are commensurate with the amounts paid for initial contracts, the deferred incremental costs will be recognized over the contract term. Capitalized commission costs, net of accumulated amortization, as of October 31, 2022 and 2021 were $96.5 million and $92.2 million, respectively. The balances are included in other long-term assets in our consolidated balance sheets. Amortization of these assets were $73.0 million, $64.7 million and $61.2 million, respectively, during fiscal 2022, fiscal 2021 and fiscal 2020, and are included in sales and marketing expense in our consolidated statements of income.

Business Combinations [Abstract]
Business Combinations	Business Combinations Fiscal 2022 NTT Security AppSec Solutions Inc. On June 22, 2022, we completed the acquisition of all outstanding shares of NTT Security AppSec Solutions Inc. (which has operated under the name WhiteHat Security, or WhiteHat), a provider of dynamic application security testing solutions, from NTT Security Corporation for an aggregate purchase price of $330.1 million in cash. With this acquisition, we have broadened our product offering in the application security testing market. The aggregate purchase consideration was preliminarily allocated as follows: (in thousands) Total purchase consideration $ 330,112 Less: cash acquired 22,849 Total purchase consideration, net of cash acquired $ 307,263 Allocations Goodwill $ 249,852 Intangible assets 97,500 Deferred revenue (40,367) Other tangible assets, net 278 $ 307,263 The goodwill was primarily attributed to the expected post-acquisition synergies from the integration of WhiteHat. The $249.9 million of goodwill was assigned to the Software Integrity reporting unit and the amount recognized was not deductible for tax purposes. The acquired identifiable intangible assets of $97.5 million were valued using the income approach. The intangible assets are being amortized over their respective useful lives ranging from 5 to 10 years. During the fourth quarter of fiscal 2022, we recorded measurement period adjustments to reflect the facts and circumstances in existence as of the acquisition date. These adjustments primarily related to the valuation of individually immaterial net tangible assets of $2.1 million with corresponding increase to goodwill. OpenLight Photonics, Inc. During the three months ended April 30, 2022, we acquired 75% equity interest in OpenLight Photonics, Inc. (OpenLight) for cash consideration of $90.0 million. The remaining 25% equity interest in OpenLight is held by Juniper Networks, Inc. (the Minority Investor) from their contribution of IP and certain tangible assets. The agreement with the Minority Investor contains redemption features whereby the interest held by the Minority Investor is redeemable either (i) at the option of the Minority Investor on or after the third anniversary of the acquisition or sooner in certain circumstances or (ii) at our option beginning on the third anniversary of the acquisition. This option is exercisable at the greater of fair value at the time of redemption or $30.0 million and was valued at $10.1 million, resulting in a total consideration of $100.1 million. The preliminary purchase price was allocated as follows: $94.0 million to identifiable intangible assets and $46.7 million to goodwill, which were attributable to the Semiconductor & System Design reporting unit. The goodwill was mainly attributable to the assembled workforce and planned growth in new markets. There was no tax-deductible goodwill related to the acquisition. During the fourth quarter of fiscal 2022, we recorded a measurement period adjustment to reflect the facts and circumstances in existence as of the acquisition date. This adjustment relates to the valuation of deferred tax assets of $1.6 million with corresponding increase to goodwill. From the date of acquisition through October 31, 2022, OpenLight incurred a net loss of $19.4 million, of which $4.9 million was attributable to redeemable non-controlling interest. As of October 31, 2022, the carrying value of the redeemable non-controlling interest was $38.7 million in the consolidated balance sheets. Other Fiscal 2022 Acquisitions During fiscal 2022, we completed two other acquisitions for aggregate purchase consideration of $31.8 million, net of cash acquired. The preliminary purchase price was allocated as follows: $12.7 million to identifiable intangible assets and $22.2 million to goodwill, which were attributable to the Semiconductor & System Design reporting unit. There was no tax-deductible goodwill related to the acquisitions. We have included the financial results of the fiscal 2022 acquisitions in our consolidated financial statements from their respective acquisition date. We do not consider these acquisitions to be material, individually or in the aggregate, to our consolidated financial statements. Fiscal 2021 During fiscal 2021, we completed several acquisitions for an aggregate consideration of $298.9 million, net of cash acquired. We do not consider these acquisitions to be material, individually or in the aggregate, to our consolidated financial statements. Total purchase consideration was primarily allocated to identifiable intangible assets of $109.3 million and goodwill of $205.8 million, of which $160.1 million is attributable to the Semiconductor & System Design reporting segment and $45.7 million is attributable to the Software Integrity reporting segment. Approximately $34.0 million of the goodwill related to the fiscal 2021 acquisitions was deductible for tax purposes. Preliminary Fair Value Estimates For all acquisitions completed in fiscal 2022, the purchase price was allocated to tangible and identifiable intangible assets acquired and liabilities assumed based on their preliminary estimated fair values, which were determined using generally accepted valuation techniques based on estimates and assumptions made by management at the time of acquisition. These estimates and assumptions are subject to change as additional information becomes available during the respective measurement period, which is not expected to exceed 12 months from applicable acquisition date. The primary areas of those preliminary estimates relate to certain tangible assets and liabilities, identifiable intangible assets, and income taxes. Acquisition-Related Transaction Costs Acquisition-related transaction costs were $14.1 million and $15.4 million during fiscal 2022 and 2021, respectively. These costs consist of professional fees and administrative costs and were expensed as incurred in our consolidated statements of income.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in business combinations. We have two reportable segments, and reporting units are determined to be the same as reportable segments. In fiscal 2022, we changed our annual assessment date from the last day of the fourth fiscal quarter to the first day of the fourth fiscal quarter to align the impairment assessment date more closely with our long-term planning and forecasting process. We performed the required annual goodwill impairment test and concluded that goodwill was not impaired.

Financial Assets and Liabilities	Financial Assets and Liabilities Cash Equivalents and Short-term investments As of October 31, 2022, the balances of our cash equivalents and short-term investments were as follows: Amortized Cost Gross Gross Gross Estimated (1) (in thousands) Cash equivalents: Money market funds $ 77,683 $ — $ — $ — $ 77,683 Total: $ 77,683 $ — $ — $ — $ 77,683 Short-term investments: U.S. government agency & T-bills $ 25,816 $ — $ (174) $ (39) $ 25,603 Municipal bonds 2,970 — (12) (80) 2,878 Corporate debt securities 95,899 7 (747) (1,135) 94,024 Asset-backed securities 25,826 — (149) (269) 25,408 Total: $ 150,511 $ 7 $ (1,082) $ (1,523) $ 147,913 (1) See Note 8. Fair Value Measurements for further discussion on fair values. Our short-term investment portfolio includes both corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. Most of our unrealized losses are due to changes in market interest rates, and bond yields. We believe that we have the ability to realize the full value of all of these investments upon maturity. As of October 31, 2022, our investments that were in a continuous loss position of 12 months or more, as well as the unrealized losses on those investments, were immaterial. The contractual maturities of our available-for-sale debt securities as of October 31, 2022 were as follows: Amortized Cost Fair Value (in thousands) Less than 1 year $ 83,234 $ 82,264 1-5 years 61,593 60,156 5-10 years 3,230 3,165 >10 years 2,454 2,328 Total $ 150,511 $ 147,913 As of October 31, 2021, the balances of our cash equivalents and short-term investments were as follows: Amortized Gross Gross Gross Estimated (1) (in thousands) Cash equivalents: Money market funds $ 172,934 $ — $ — $ — $ 172,934 Total: $ 172,934 $ — $ — $ — $ 172,934 Short-term investments: U.S. government agency & T-bills $ 6,447 $ — $ (5) $ — $ 6,442 Municipal bonds 4,588 — (12) — 4,576 Corporate debt securities 103,615 7 (170) — 103,452 Asset-backed securities 33,545 6 (72) — 33,479 Total: $ 148,195 $ 13 $ (259) $ — $ 147,949 (1) See Note 8. Fair Value Measurements for further discussion on fair values. Restricted cash We include amounts generally described as restricted cash in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. Restricted cash is primarily associated with office leases. The following table provided a reconciliation of cash, cash equivalents and restricted cash included in the consolidated balance sheets: October 31, 2022 2021 (in thousands) Cash and cash equivalents $ 1,417,608 $ 1,432,840 Restricted cash included in prepaid and other current assets 1,566 1,560 Restricted cash included in other long-term assets 690 783 Total cash, cash equivalents and restricted cash $ 1,419,864 $ 1,435,183 Non-marketable equity securities Our portfolio of non-marketable equity securities consists of strategic investments in privately held companies. There were no material impairments of non-marketable equity securities in fiscal 2022, fiscal 2021, or fiscal 2020. Derivatives We recognize derivative instruments as either assets or liabilities in the consolidated balance sheets at fair value and provide qualitative and quantitative disclosures about such derivatives. We operate internationally and are exposed to potentially adverse movements in foreign currency exchange rates. We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions including: (1) certain assets and liabilities, (2) shipments forecasted to occur within approximately one month, (3) future billings and revenue on previously shipped orders, and (4) certain future intercompany invoices denominated in foreign currencies. The duration of forward contracts, the majority of which are short-term, ranges from approximately 1 month to 27 months at inception. We do not use foreign currency forward contracts for speculative or trading purposes. We enter into foreign exchange forward contracts with high credit quality financial institutions that are rated "A" or above and to date have not experienced nonperformance by counterparties. In addition, we mitigate credit risk in derivative transactions by permitting net settlement of transactions with the same counterparty and anticipate continued performance by all counterparties to such agreements. The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets. The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting. The cash flow impact upon settlement of the derivative contracts is included in “net cash provided by operating activities” in the consolidated statements of cash flows. Cash Flow Hedging Activities Certain foreign exchange forward contracts are designated and qualify as cash flow hedges. These contracts have durations of approximately 27 months or less. Certain forward contracts are rolled over periodically to capture the full length of exposure to our foreign currency risk, which can be up to three years. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on the hedged transactions. The related gains or losses resulting from changes in fair value of these hedges is initially reported, net of tax, as a component of other comprehensive income (loss) (OCI), in stockholders’ equity and reclassified into revenue or operating expenses, as appropriate, at the time the hedged transactions affect earnings. We expect a majority of the hedge balance in OCI to be reclassified to the statements of income within the next 12 months. We did not record any gains or losses related to discontinuation of cash flow hedges for fiscal years 2022, 2021 and 2020. Non-designated Hedging Activities Our foreign exchange forward contracts that are used to hedge non-functional currency denominated balance sheet assets and liabilities are not designated as hedging instruments. Accordingly, any gains or losses from changes in the fair value of the forward contracts are recorded in other income (expense), net. The gains and losses on these forward contracts generally offset the gains and losses associated with the underlying assets and liabilities, which are also recorded in other income (expense), net. The duration of the forward contracts for hedging our balance sheet exposure is approximately one month. We also have certain foreign exchange forward contracts for hedging certain international revenues and expenses that are not designated as hedging instruments. Accordingly, any gains or losses from changes in the fair value of the forward contracts are recorded in other income (expense), net. The gains and losses on these forward contracts generally offset the gains and losses associated with the foreign currency in operating income. The duration of these forward contracts is usually less than one year. The overall goal of our hedging program is to minimize the impact of currency fluctuations on the net income over the fiscal year. The effects of the non-designated derivative instruments on our consolidated statements of income for fiscal years 2022, 2021, and 2020 were summarized as follows: October 31, 2022 2021 2020 (in thousands) Gains (losses) recorded in other income (expense), net $ (15,851) $ (855) $ 1,957 The notional amounts in the table below for derivative instruments provided one measure of the transaction volume outstanding: October 31, 2022 2021 (in thousands) Total gross notional amounts $ 1,386,140 $ 1,176,152 Net fair value $ (50,080) $ 13,404 Our exposure to the market gains or losses will vary over time as a function of currency exchange rates. The amounts ultimately realized upon settlement of these financial instruments, together with the gains and losses on the underlying exposures, will depend on actual market conditions during the remaining life of the instruments. The following table represented the consolidated balance sheets location and amount of derivative instrument fair values segregated between designated and non-designated hedge instruments: Fair values of Fair values of (in thousands) Balance at October 31, 2022 Other current assets $ 2,315 $ 223 Accrued liabilities $ 52,171 $ 447 Balance at October 31, 2021 Other current assets $ 15,455 $ 17 Accrued liabilities $ 2,027 $ 42 The following table represented the location of the amount of gains and losses on derivative instrument fair values for designated hedge instruments, net of tax in the consolidated statements of income: Location of gains (losses) Amount of gains (losses) Location of gains (losses) Amount of (in thousands) Fiscal year ended October 31, 2022 Foreign exchange contracts Revenue $ (19,755) Revenue $ 10,975 Foreign exchange contracts Operating expenses (59,314) Operating expenses (15,869) Total $ (79,069) $ (4,894) Fiscal year ended October 31, 2021 Foreign exchange contracts Revenue $ 1,148 Revenue $ 4,181 Foreign exchange contracts Operating expenses 8,712 Operating expenses 10,378 Total $ 9,860 $ 14,559 Fiscal year ended October 31, 2020 Foreign exchange contracts Revenue $ 3,034 Revenue $ 530 Foreign exchange contracts Operating expenses 4,800 Operating expenses (603) Total $ 7,834 $ (73) Other Commitments — Credit and Term Loan On January 22, 2021, we entered into a Fourth Extension and Amendment Agreement (the Fourth Amendment), which amended and restated our previous credit agreement, dated as of November 28, 2016 (as amended and restated, the Credit Agreement). Our outstanding borrowings under the previous credit agreement, which as of January 22, 2021 consisted of term loans in the aggregate principal amount of $97.5 million, were carried over under the Credit Agreement and fully paid on November 26, 2021. The Fourth Amendment extended the termination date of the existing $650.0 million senior unsecured revolving credit facility (the Revolver) from November 28, 2021 to January 22, 2024, which could be further extended at our option. The Credit Agreement also provides an uncommitted incremental loan facility of up to $150.0 million in the aggregate principal amount. The Credit Agreement contains financial covenants requiring us to maintain a maximum consolidated leverage ratio and a minimum consolidated interest coverage ratio, as well as other non-financial covenants. As of October 31, 2022, we were in compliance with all financial covenants. There was no outstanding balance under the Revolver as of October 31, 2022 and October 31, 2021. We expect our borrowings, if any, under the Revolver will fluctuate from quarter to quarter. Borrowings bear interest at a floating rate based on a margin over our choice of market observable base rates as defined in the Credit Agreement. As of October 31, 2022, the Revolver bore interest at LIBOR +1%. In addition, commitment fees are payable on the Revolver at rates between 0.125% and 0.200% per year based on our leverage ratio on the daily amount of the revolving commitment. In July 2018, we entered into a 12-year 220.0 million Renminbi (approximately $33.0 million) credit agreement with a lender in China to support our facilities expansion. Borrowings bear interest at a floating rate based on the 5-year Loan Prime Rate plus 0.74%. As of October 31, 2022, we had a $20.8 million outstanding balance under the agreement. The carrying amount of the short-term and long-term debt approximates the estimated fair value.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820-10, Fair Value Measurements and Disclosures , defines fair value, establishes guidelines and enhances disclosure requirements for fair value measurements. The accounting guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance also establishes a fair value hierarchy based on the independence of the source and objective evidence of the inputs used. There are three fair value hierarchies based upon the level of inputs that are significant to fair value measurement: Level 1 —Observable inputs that reflect quoted prices (unadjusted) for identical instruments in active markets; Level 2 —Observable inputs other than quoted prices included in Level 1 for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3 —Unobservable inputs to the valuation derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable. On a recurring basis, we measure the fair value of certain assets and liabilities, which include cash equivalents, short-term investments, non-qualified deferred compensation plan assets, and foreign currency derivative contracts. Our cash equivalents and short-term investments are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs. Our non-qualified deferred compensation plan assets consist of money market and mutual funds invested in domestic and international marketable securities that are directly observable in active markets and are therefore classified within Level 1. Our foreign currency derivative contracts are classified within Level 2 because these contracts are not actively traded and the valuation inputs are based on quoted prices and market observable data of similar instruments. Our borrowings under our Credit and Term Loan facilities are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available to us for debt with similar terms and maturities. See Note 7 . Financial Assets and Liabilities for more information on these borrowings.

These leases have various expiration dates through December 31, 2040, some of which include options to extend the leases for up to 10 years. Because we are not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term and associated potential option payments are excluded from lease payments.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Legal Proceedings We are subject to routine legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of our business. The ultimate outcome of any litigation is often uncertain and unfavorable outcomes could have a negative impact on our results of operations and financial condition. We regularly review the status of each significant matter and assess its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount is estimable, we accrue a liability for the estimated loss. Legal proceedings are inherently uncertain and as circumstances change, it is possible that the amount of any accrued liability may increase, decrease, or be eliminated. We have determined that, except as set forth below, no disclosure of estimated loss is required for a claim against us because: (1) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (2) a reasonably possible loss or range of loss cannot be estimated; or (3) such estimate is immaterial. Mentor Patent Litigation Prior to the legal settlement as further described below, we were engaged in complex patent litigation with Mentor Graphics Corporation (Mentor) involving several actions in different forums. We succeeded to the litigation when we acquired Emulation & Verification Engineering S.A. on October 4, 2012. Legal Settlement In March 2017, Siemens PLM Software (Siemens) acquired Mentor. On June 29, 2018, we, Siemens and Mentor settled all outstanding patent litigation between us and Mentor for a $65.0 million payment made from us to Mentor. As a result of the settlement, the litigation with Mentor was dismissed and the injunction entered in connection with that litigation was vacated. The settlement included mutual seven-year patent cross-licenses between us and Siemens, and between us and Mentor. We and Mentor also amended an existing interoperability agreement to collaborate on a wide range of EDA products for the benefit of our mutual customers. The amendment includes a one-time termination charge between $0.0 and $25.0 million, payable to Mentor under certain conditions. Tax Matters We undergo examination from time to time by U.S. and foreign authorities for non-income based taxes, such as sales, use and value-added taxes, and are currently under examination by tax authorities in certain jurisdictions. If the potential loss from such examinations is considered probable and the amount or the range of loss could be estimated, we would accrue a liability for the estimated expense. In addition to the foregoing, we are, from time to time, party to various other claims and legal proceedings in the ordinary course of our business, including with tax and other governmental authorities. For a description of certain of these other matters, refer to Note 15. Income Taxes.

Stock Repurchase Program [Abstract]
Stock Repurchase Program	Stock Repurchase Program Our Board of Directors (the Board) previously approved a stock repurchase program (the Program) with authorization to purchase up to $1.0 billion of our common stock in December 2021. The Board approved a replenishment of the Program with authorization to purchase up to $1.5 billion in September 2022. As of October 31, 2022, $1.4 billion remained available for future repurchases under the program. In August 2022, we entered into an accelerated stock repurchase agreement (the August 2022 ASR) to repurchase an aggregate of $240.0 million of our common stock.

Share-Based Payment Arrangement [Abstract]
Employee Benefit Plans	Employee Benefit Plans Employee Stock Purchase Plan Under our Employee Stock Purchase Plan (ESPP), participating employees are granted the right to purchase shares of common stock at a price per share that is 85% of the lesser of the fair market value of the shares at (1) the beginning of an offering period (generally, a rolling two year period) or (2) the purchase date (generally occurring at the end of each semi-annual purchase period), subject to the terms of ESPP, including a limit on the number of shares that may be purchased in a purchase period. On April 9, 2020 and April 12, 2022, our stockholders approved amendments to the ESPP to increase the number of shares of common stock authorized for issuance under the plan by 5.0 million and 2.0 million shares, respectively. During fiscal 2022, 2021 and 2020, we issued 0.7 million, 1.0 million, and 1.0 million shares, respectively, under the ESPP at average per share prices of $195.48, $134.26 and $103.41, respectively. As of October 31, 2022, 14.1 million shares of common stock were reserved for future issuance under the ESPP. Equity Compensation Plans 2006 Employee Equity Incentive Plan. On April 25, 2006, our stockholders approved the 2006 Employee Equity Incentive Plan (2006 Employee Plan), which provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and other forms of equity compensation, including performance stock awards and performance cash awards, as determined by the plan administrator. The terms and conditions of each type of award are set forth in the 2006 Employee Plan and in the award agreements governing particular awards. Restricted stock units are granted under the 2006 Employee Plan as part of our incentive compensation program. In general, restricted stock units vest over three On April 8, 2021 and April 12, 2022, our stockholders amended the 2006 Employee Plan to, among other things, increase the number of shares of common stock reserved for future issuance under the plan by 4.7 million shares and 3.0 million shares, respectively. As of October 31, 2022, an aggregate of 2.1 million stock options and 4.6 million restricted stock units were outstanding, and 13.1 million shares were available for future issuance under the 2006 Employee Plan. 2005 and 2017 Non-Employee Directors Equity Incentive Plans. On April 6, 2017, our stockholders approved the 2017 Non-Employee Directors Equity Incentive Plan (2017 Directors Plan). In connection with stockholder approval of the 2017 Directors Plan, the 2005 Non-Employee Directors Equity Incentive Plan (2005 Directors Plan) was terminated as of April 6, 2017, and no awards could be granted under the 2005 Directors Plan after that date. Under the 2005 Directors Plan, we granted options, which vest over a period of three The 2017 Directors Plan provides for equity awards to non-employee directors in the form of stock options, restricted stock units, restricted stock or a combination thereof. On April 6, 2017, our stockholders approved an aggregate of 0.45 million shares of common stock reserved under the 2017 Directors Plan. We grant restricted stock awards and options under the 2017 Directors Plan. Restricted stock awards generally vest on an annual basis and options vest over a period of three years. As of October 31, 2022, 4,985 shares of restricted stock awards were unvested and 12,792 stock options were outstanding, and a total of 373,213 shares of common stock were reserved for future issuance under the 2017 Directors Plan. Other Assumed Stock Plans through Acquisitions. We have assumed certain outstanding stock awards of acquired companies, including restricted stock units and options. If these assumed equity awards are canceled, forfeited or expire unexercised, the underlying shares do not become available for future grant. As of October 31, 2022, 0.1 million shares of our common stock remained subject to such outstanding assumed equity awards. Restricted Stock Units. The following table contained information concerning activities related to restricted stock units granted under the 2006 Employee Plan and assumed from acquisitions: Restricted Stock Units Outstanding (1) Weighted Weighted Aggregate (in thousands, except per share amounts and years) Balance at October 31, 2019 3,857 $ 97.21 1.56 Granted (2) 2,041 $ 168.15 Vested (3) (1,480) $ 88.70 $ 261,563 Forfeited (288) $ 104.67 Balance at October 31, 2020 4,130 $ 134.80 1.47 Granted (2) 1,901 $ 258.58 Vested (3) (1,565) $ 122.01 $ 421,034 Forfeited (279) $ 167.76 Balance at October 31, 2021 4,187 $ 193.58 1.39 Granted (2) 2,402 $ 323.46 Vested (3) (1,589) $ 170.36 $ 529,766 Forfeited (362) $ 228.70 Balance at October 31, 2022 4,638 $ 265.76 1.32 (1) No restricted stock units were assumed in connection with acquisitions in the last three fiscal years, but the balance at fiscal year-end included certain restricted stock units that were previously assumed in connection with acquisitions. (2) The number of granted restricted stock units included those granted to senior management with performance-based vesting criteria (in addition to service-based vesting criteria) (performance-based RSUs) reported at the maximum possible number of shares that may ultimately be issuable if all applicable performance-based criteria are achieved at their maximum levels and all applicable service-based criteria are fully satisfied. (3) The number of vested restricted stock units included shares that were withheld on behalf of employees to satisfy the minimum statutory tax withholding requirements. Stock Options. The following table summarized stock option activity and included stock options granted under all equity plans: Options Outstanding Shares Under Stock Option (1) Weighted- Weighted- Aggregate (in thousands, except per share amounts and years) Balance at October 31, 2019 5,290 $ 65.57 4.08 $ 373,112 Granted 700 $ 143.44 Exercised (1,891) $ 51.76 Canceled/forfeited/expired (106) $ 84.14 Balance at October 31, 2020 3,993 $ 85.26 4.10 $ 513,845 Granted 353 $ 239.46 Exercised (1,203) $ 66.50 Canceled/forfeited/expired (36) $ 128.49 Balance at October 31, 2021 3,107 $ 109.51 3.81 $ 694,921 Granted 293 $ 342.86 Exercised (1,126) $ 86.24 Canceled/forfeited/expired (114) $ 164.46 Balance at October 31, 2022 2,160 $ 150.37 3.57 $ 328,120 Vested and expected to vest as of October 31, 2022 2,160 $ 150.37 3.57 $ 328,120 Exercisable at October 31, 2022 1,449 $ 103.44 2.77 $ 278,915 (1) No stock options were assumed in connection with acquisitions in the last three fiscal years, but the balance at fiscal year-end included certain stock options that were previously assumed in connection with acquisitions. The aggregate intrinsic value in the preceding table represented the pre-tax intrinsic value based on stock options with an exercise price less than our closing stock price of $295.84 as of October 31, 2022. The pre-tax intrinsic value of options exercised and their average exercise prices were: Year Ended October 31, 2022 2021 2020 (in thousands, except per share price) Intrinsic value $ 273,524 $ 254,587 $ 218,640 Average exercise price per share $ 86.24 $ 66.50 $ 51.76 Restricted Stock Units and Stock Options. The following table contained additional information concerning activities related to stock options and restricted stock units that were granted under the 2006 Employee Plan and assumed from acquisitions: Available for Grant (1)(2) (in thousands) Balance at October 31, 2019 12,208 Options granted (2) (694) Options canceled/forfeited/expired (2) 102 Restricted stock units granted (1) (3,469) Restricted stock units forfeited (1) 482 Additional shares reserved 3,500 Balance at October 31, 2020 12,129 Options granted (2) (353) Options canceled/forfeited/expired (2) 36 Restricted stock units granted (1) (3,232) Restricted stock units forfeited (1) 471 Additional shares reserved 4,700 Balance at October 31, 2021 13,751 Options granted (2) (286) Options canceled/forfeited/expired (2) 114 Restricted stock units granted (1)(3) (4,083) Restricted stock units forfeited (1) 615 Additional shares reserved 3,000 Balance at October 31, 2022 13,111 (1) Restricted stock units included awards granted under the 2006 Employee Plan and assumed through acquisitions. The number of RSUs reflects the application of the award multiplier of 1.70 as described above. (2) Options granted by us are not subject to the award multiplier ratio described above. (3) The number of granted restricted stock units included those granted to senior management with market-based vesting and performance-based vesting criteria (in addition to service-based vesting criteria) (market-based RSUs) reported at the maximum possible number of shares that may ultimately be issuable if all applicable market-based and performance-based criteria are achieved at their maximum levels and all applicable service-based criteria are fully satisfied. Restricted Stock Awards . The following table summarized restricted stock award activities during fiscal 2022 under the 2005 Directors Plan and 2017 Directors Plan: Restricted Weighted-Average (in thousands, except per share amounts) Unvested at October 31, 2019 11 $ 116.43 Granted 9 $ 140.97 Vested (11) $ 116.43 Forfeited — $ — Unvested at October 31, 2020 9 $ 140.97 Granted 5 $ 261.01 Vested (9) $ 140.97 Forfeited — $ — Unvested at October 31, 2021 5 $ 261.01 Granted 5 $ 310.02 Vested (5) $ 261.01 Forfeited — $ — Unvested at October 31, 2022 5 $ 310.02 Valuation and Expense of Stock-Based Compensation. We estimate the fair value of stock options and employee stock purchase rights under the ESPP on the grant date. The value of awards expected to vest is recognized as expense over the applicable service periods. We use the straight-line attribution method to recognize stock-based compensation costs over the service period of the award except for performance grants with specific performance criteria. With respect to such performance grants in each reporting period, we estimate the probability of achievement of applicable performance goals and recognize related stock-based compensation expense using the graded-vesting method. The amount of stock-based compensation expense recognized in any 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. We use the Black-Scholes option-pricing model to determine the fair value of stock options and employee stock purchase plan rights . The Black-Scholes option-pricing model incorporates various subjective assumptions including expected volatility, expected term and interest rates. The expected volatility for both stock options and employee stock purchase rights is estimated by a combination of implied volatility for publicly traded options of our common stock with a term of six months or longer and the historical stock price volatility over the estimated expected term of such awards, which is based on historical experience. Restricted stock units are valued based on the closing price of our common stock on the grant date. The fair value for market-based RSUs is estimated on the grant date using a Monte Carlo simulation model with the following assumptions: expected volatilities ranging from 33.01% to 37.8%, based on the historical volatilities of our common stock and peer companies' common stock over the remaining performance period; risk-free interest rate ranging from 1.33% to 3.46%, based on the yield of the zero-coupon U.S. Treasury bill that is commensurate with the remaining performance period; and an expected term of 1.16 to 1.69 years, based on the remaining performance period of the market-based award. The assumptions presented in the following table were used to estimate the fair value of stock options and employee stock purchase rights granted under our stock plans: Year Ended October 31, 2022 2021 2020 Stock Options Expected life (in years) 4.1 4.1 4.1 Risk-free interest rate 1.07%- 4.42% 0.35% - 1.00% 0.26% - 1.71% Volatility 32.28% -37.04% 29.19% - 32.28% 23.05%- 32.80% Weighted average estimated fair value $98.07 $61.58 $33.02 ESPP Expected life (in years) 0.5 - 2.0 0.5 - 2.0 0.5 - 2.0 Risk-free interest rate 0.67% - 3.44% 0.00% - 0.19% 0.09% - 1.24% Volatility 34.51% - 38.69% 28.02% - 39.68% 25.59% - 43.06% Weighted average estimated fair value $102.63 $89.82 $47.69 The compensation cost recognized in the consolidated statements of income for our stock compensation arrangements was as follows: Year Ended October 31, 2022 (1) 2021 2020 (in thousands) Cost of products $ 55,134 $ 38,345 $ 27,193 Cost of maintenance and service 24,146 13,817 9,327 Research and development expense 241,978 171,013 125,814 Sales and marketing expense 81,617 61,940 43,205 General and administrative expense 56,154 60,157 43,045 Stock-based compensation expense before taxes 459,029 345,272 248,584 Income tax benefit (74,271) (53,483) (39,077) Stock-based compensation expense after taxes $ 384,758 $ 291,789 $ 209,507 (1) During fiscal 2022, we recognized stock-based compensation expense relating to restricted stock units, granted to senior executives in February, May and August 2022 with certain market, performance and service conditions (market-based RSUs). Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The performance period during which the achievement goals will be measured is fiscal 2022 and fiscal 2023. The maximum potential awards that may be earned are 187.5% of the target number of the initial awards. The awards will vest in equal increments in December 2023 and December 2024 if the TSR target, revenue growth metrics, and service conditions are achieved. As of October 31, 2022, we had $999.7 million of total unrecognized stock-based compensation expense relating to options, RSUs and restricted stock awards, which is expected to be recognized over a weighted average period of 2.2 years. As of October 31, 2022, we had $77.6 million of total unrecognized stock-based compensation expense relating to the ESPP, which is expected to be recognized over a period of 2.0 years. Deferred Compensation Plan. We maintain the Synopsys Deferred Compensation Plan (Deferred Plan), which permits eligible employees to defer up to 50% of their annual cash base compensation and up to 100% of their eligible cash variable compensation. Amounts may be withdrawn from the Deferred Plan pursuant to elections made by the employees in accordance with the terms of the plan. Since the inception of the Deferred Plan, we have not made any matching or discretionary contributions to the Deferred Plan. There are no Deferred Plan provisions that provide for any guarantees or minimum return on investments. Undistributed amounts under the Deferred Plan are subject to the claims of our creditors. The securities held by the Deferred Plan are classified as trading securities. Deferred plan assets and liabilities were as follows: As of October 31, 2022 As of October 31, 2021 (in thousands) Plan assets recorded in other long-term assets $ 279,096 $ 343,820 Plan liabilities recorded in other long-term liabilities (1) $ 279,096 $ 343,820 (1) Undistributed deferred compensation balances due to participants. Income or loss from the change in fair value of the Deferred Plan assets is recorded in other income (expense), net. The increase or decrease in the fair value of the undistributed Deferred Plan obligation is recorded in total cost of revenue and operating expense. The following table summarized the impact of the Deferred Plan: Year Ended October 31, 2022 2021 2020 (in thousands) Increase (reduction) to cost of revenue and operating expense $ (68,778) $ 71,603 $ 21,469 Other income (expense), net (68,778) 71,603 21,469 Net increase (decrease) to net income $ — $ — $ — Other Retirement Plans. We sponsor various defined contribution retirement plans for our eligible U.S. and non-U.S. employees. Total contributions to these plans were $51.2 million, $49.4 million, and $41.7 million in fiscal 2022, 2021, and 2020, respectively. For employees in the United States and Canada, we match pre-tax employee contributions up to a maximum of U.S. $3,000 and Canadian $4,000, respectively, per participant per year. Certain of our international subsidiaries sponsor defined benefit retirement plans. The unfunded projected benefit obligation for these defined benefit retirement plans as of October 31, 2022 and 2021 was immaterial and recorded in other long-term liabilities in our consolidated balance sheets.

Where foreign subsidiaries are considered indefinitely reinvested, and if the tax effect of undistributed earnings and other outside basis differences were recognized, the nature of taxes expected would be primarily withholding taxes, taxes in non-conforming states, and taxes on intermediate holding companies outside of the U.S., net of foreign tax credits where available. As of October 31, 2022, the taxes due, after allowable foreign tax credits, are not expected to be material. The significant components of deferred tax assets and liabilities were as follows: October 31, 2022 2021 (in thousands) Net deferred tax assets: Deferred tax assets: Deferred revenue 41,941 30,113 Deferred compensation 67,782 59,823 Intangible and depreciable assets 119,791 117,211 Capitalized research and development costs 231,733 203,052 Stock-based compensation 60,537 40,922 Tax loss carryovers 59,754 30,305 Foreign tax credit carryovers 27,153 32,498 Research and other tax credit carryovers 316,650 326,164 Operating Lease Liabilities 119,575 94,519 Other 16,887 — Gross deferred tax assets 1,061,803 934,607 Valuation allowance (198,213) (174,117) Total deferred tax assets 863,590 760,490 Deferred tax liabilities: Intangible assets 102,796 61,448 Operating lease Right-of-Use-Assets 96,598 77,877 Accruals and reserves 5,998 6,216 Undistributed earnings of foreign subsidiaries 1,000 7,580 Other — 628 Total deferred tax liabilities 206,392 153,749 Net deferred tax assets $ 657,198 $ 606,741 It is more likely than not that the results of future operations will be able to generate sufficient taxable income to realize the net deferred tax assets. The valuation allowance provided against our deferred tax assets as of October 31, 2022 is mainly attributable to foreign tax credits available to non-U.S. subsidiaries and the California research credits. The valuation allowance increased by a net of $24.1 million in fiscal 2022 primarily related to the net increase of valuation allowance on California research credits. We have the following tax loss and credit carryforwards available to offset future income tax liabilities: Carryforward Amount Expiration (in thousands) Federal net operating loss carryforward $ 142,645 2023-2041 Federal research credit carryforward 140,331 2023-2042 Federal foreign tax credit carryforward 16,813 2027-2033 International foreign tax credit carryforward 12,025 Indefinite International net operating loss carryforward 37,086 2027-Indefinite California research credit carryforward 226,519 Indefinite Other state research credit carryforward 20,743 2025-2042 State net operating loss carryforward 198,348 2023-2044 The federal and state net operating loss carryforward is from acquired companies and the annual use of such loss is subject to significant limitations under Internal Revenue Code Section 382 and certain provisions of the Tax Act. Foreign tax credits may only be used to offset tax attributable to foreign source income. The gross unrecognized tax benefits decreased by approximately $1.2 million during fiscal 2022 resulting in gross unrecognized tax benefits of $81.2 million as of October 31, 2022. A reconciliation of the beginning and ending balance of gross unrecognized tax benefits is summarized as follows: As of October 31, 2022 As of October 31, 2021 (in thousands) Beginning balance $ 82,360 $ 83,149 Increases in unrecognized tax benefits related to prior year tax positions 435 794 Decreases in unrecognized tax benefits related to prior year tax positions (9,791) (7,372) Increases in unrecognized tax benefits related to current year tax positions 6,794 9,168 Decreases in unrecognized tax benefits related to settlements with taxing authorities (1,104) (1,538) Reductions in unrecognized tax benefits due to lapse of applicable statute of limitations (2,601) (1,235) Increases in unrecognized tax benefits acquired 14,121 — Changes in unrecognized tax benefits due to foreign currency translation (9,031) (606) Ending balance $ 81,183 $ 82,360 As of October 31, 2022 and 2021, approximately $81.2 million and $82.4 million, respectively, of the unrecognized tax benefits would affect our effective tax rate if recognized upon resolution of the uncertain tax positions. Interest and penalties related to estimated obligations for tax positions taken in our tax returns are recognized as a component of income tax expense (benefit) in the consolidated statements of income and totaled approximately $0.8 million , $0.4 million and $0.2 million for fiscal years 2022, 2021 and 2020, respectively. As of October 31, 2022 and 2021, the combined amount of accrued interest and penalties related to tax positions taken on our tax returns was approximately $12.7 million and $13.5 million, respectively. The timing of the resolution of income tax examinations, and the amounts and timing of various tax payments that are part of the settlement process, are highly uncertain. Variations in such amounts and/or timing could cause large fluctuations in the balance sheet classification of current and non-current assets and liabilities. We believe that in the coming 12 months, it is reasonably possible that either certain audits and ongoing tax litigation will conclude or the statute of limitations on certain state and foreign income and withholding taxes will expire, or both. Given the uncertainty as to ultimate settlement terms, the timing of payment and the impact of such settlements on other uncertain tax positions, the range of the estimated potential decrease in underlying unrecognized tax benefits is between $0.0 and $28.0 million. We and/or our subsidiaries remain subject to tax examination in the following jurisdictions: Jurisdiction Year(s) Subject to Examination United States Fiscal years after 2020 California Fiscal years after 2017 Hungary Fiscal years after 2018 Ireland Fiscal years after 2017 Japan Fiscal years after 2016 Korea and Taiwan Fiscal years after 2020 China Fiscal years after 2012 India Fiscal years after 2018 In addition, we have made acquisitions with operations in several of our significant jurisdictions which may have years subject to examination different from the years indicated in the above table. IRS Examinations In fiscal 2021, the Examination Division of the IRS completed its pre-filing review for fiscal 2020 and as a result we recognized approximately $7.1 million in unrecognized tax benefits, primarily due to the allowance of research tax credits. In fiscal 2020, we reached partial settlement with the Examination Division of the IRS for fiscal 2019 and recognized approximately $6.3 million in unrecognized tax benefits, primarily due to the allowance of certain foreign tax credits and research tax credits. State Examinations In fiscal 2020, we reached final settlement with the California Franchise Tax Board for fiscal 2015, 2016, and 2017. As a result of the settlement, we recognized $20.2 million in unrecognized tax benefits and increased our valuation allowance by $20.2 million. Non-U.S. Examinations Hungarian Tax Authority In 2017, the Hungarian Tax Authority (the HTA) assessed withholding taxes of approximately $25.0 million and interest and penalties of $11.0 million, against our Hungary subsidiary (Synopsys Hungary). Synopsys Hungary contested the assessment with the Hungarian Administrative Court (Administrative Court). In 2019, as required under Hungarian law, Synopsys Hungary paid the assessment and recorded a tax expense due to an unrecognized tax benefit of $17.4 million, which is net of estimated U.S. foreign tax credits. The Administrative Court found against Synopsys Hungary, and we appealed to the Hungarian Supreme Court. During 2021, the Hungarian Supreme Court heard our appeal and remanded the case to the Administrative Court for further proceedings. The Administrative Court once again ruled against Synopsys Hungary, and we filed another appeal with the Hungarian Supreme Court. The Hungarian Supreme Court heard our appeal on January 27, 2022, vacated the lower court's decision and remanded th e case back to the Administrative Court for further proceedings . Hearings with the Administrative Court were held on June 30, 2022 and September 22, 2022. In response to a request by the Administrative Court, we filed an additional brief on November 23, 2022. We expect a hearing to be scheduled in early 2023.

Segment Reporting [Abstract]
Segment Disclosure	Segment Disclosure Segment reporting is based upon the “management approach,” i.e., how management organizes our operating segments for which separate financial information is (1) available and (2) evaluated regularly by the Chief Operating Decision Maker (CODM) in deciding how to allocate resources and in assessing performance. Until the second quarter of fiscal 2022, we had two CODMs, our two Co-Chief Executive Officers. One of our Co-Chief Executive Officers transitioned out of this role effective May 1, 2022. Commencing in the third quarter of fiscal 2022, our CODM is our sole Chief Executive Officer. We have two reportable segments: (1) Semiconductor & System Design, which includes EDA tools, IP products, system integration solutions and other associated revenue categories, and (2) Software Integrity, which includes a comprehensive solution for building integrity—security, quality and compliance testing—into the customers’ software development lifecycle and supply chain. The financial information provided to and used by the CODM to assist in making operational decisions, allocating resources, and assessing performance reflects consolidated financial information as well as revenue, adjusted operating income, and adjusted operating margin information for the Semiconductor & System Design and Software Integrity segments, accompanied by disaggregated information relating to revenue by geographic region. Information by reportable segment was as follows: Year Ended October 31, 2022 2021 2020 (in thousands) Total Segments: Revenue $ 5,081,542 $ 4,204,193 $ 3,685,281 Adjusted operating income 1,675,102 1,281,389 1,031,630 Adjusted operating margin 33 % 30 % 28 % Semiconductor & System Design: Revenue $ 4,615,714 $ 3,810,409 $ 3,327,211 Adjusted operating income 1,628,108 1,243,078 990,837 Adjusted operating margin 35 % 33 % 30 % Software Integrity: Revenue $ 465,828 $ 393,784 $ 358,070 Adjusted operating income 46,994 38,311 40,793 Adjusted operating margin 10 % 10 % 11 % Certain operating expenses are not allocated to the segments and are managed at a consolidated level. The unallocated expenses managed at a consolidated level, including amortization of intangible assets, stock-based compensation, changes in the fair value of deferred compensation plan and certain other operating expenses, were presented in the table below to provide a reconciliation of the total adjusted operating income from segments to our consolidated operating income: Year Ended October 31, 2022 2021 2020 (in thousands) Total segment adjusted operating income $ 1,675,102 $ 1,281,389 $ 1,031,630 Reconciling items: Amortization of intangible assets (96,690) (82,380) (91,281) Stock-based compensation expense (459,029) (345,272) (248,584) Deferred compensation plan 68,778 (71,603) (21,469) Other (26,123) (47,344) (50,155) Total operating income $ 1,162,038 $ 734,790 $ 620,141 The CODM does not use total assets by segment to evaluate segment performance or allocate resources. As a result, total assets by segment are not required to be disclosed. In allocating revenue to particular geographic areas, the CODM considers where individual “seats” or licenses to our products are located. Revenue is defined as revenue from external customers. Revenue and property and equipment, net, related to operations in the United States and other geographic areas were: Year Ended October 31, 2022 2021 2020 (in thousands) Revenue: United States $ 2,349,766 $ 1,951,964 $ 1,774,348 Europe 493,430 440,825 385,287 China 795,405 562,711 420,829 Korea 531,542 427,471 389,008 Other 911,399 821,222 715,809 Consolidated $ 5,081,542 $ 4,204,193 $ 3,685,281 As of October 31, 2022 2021 (in thousands) Property and Equipment, net: United States $ 297,780 $ 283,602 Other 185,520 188,796 Total $ 483,300 $ 472,398 Geographic revenue data for multi-regional, multi-product transactions reflect internal allocations and are therefore subject to certain assumptions and to our allocation methodology. One customer, including its subsidiaries, accounted for 11.7%, 10.6%, and 12.4% of our consolidated revenue in fiscal 2022, 2021, and 2020, respectively. No customer was responsible for over 10% of our accounts receivables as of October 31, 2022 and 2021.

Restructuring Charges

Restructuring Charges	12 Months Ended

Payables and Accruals [Abstract]
Restructuring Charges	Restructuring Charges In the third quarter of fiscal 2021, we initiated a restructuring plan for involuntary and voluntary employee termination and facility closure actions as part of a business reorganization (the 2021 Plan). The 2021 Plan consisted primarily of severance, retirement benefits under the 2021 Voluntary Retirement Program (2021 VRP) and lease abandonment costs, and was substantially completed in the first quarter of fiscal 2022. Total charges under the 2021 Plan were $45.5 million. During fiscal 2022, we recorded restructuring charges of $12.1 million and made payments of $26.3 million under the 2021 Plan. As of October 31, 2022, the outstanding restructuring related liabilities were immaterial and recorded in accounts payable and accrued liabilities in the consolidated balance sheets. During fiscal 2021, we recorded restructuring charges of $33.4 million and made payments of $19.2 million under the 2021 Plan. As of October 31, 2021, $14.2 million of payroll and related benefits liabilities remained outstanding and was recorded in accounts payable and accrued liabilities in the consolidated balance sheets. The remaining balance was paid in fiscal 2022. During fiscal 2020, we recorded restructuring charges of $36.1 million under the 2019 restructuring plan. These charges consisted primarily of severance and retirement benefits. $57.4 million was paid in fiscal 2020 which included payments of remaining balances in fiscal 2019. As of October 31, 2020, $1.3 million remained outstanding and was recorded in accounts payable and accrued liabilities as payroll and related benefits in the consolidated balance sheets. The remaining balance was paid in fiscal 2021.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Oct. 31, 2022
Accounting Policies [Abstract]
Fiscal Year End	Our fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, we have a 53-week year. When a 53-week year occurs, we include the additional week in the first quarter to realign fiscal quarters with calendar quarters. Fiscal 2022, 2021 and 2020 were 52-week years ending on October 29, 2022, October 30, 2021 and October 31, 2020, respectively. For presentation purposes, the consolidated financial statements and accompanying notes refer to the closest calendar month end. Fiscal 2023 will be a 52-week year.
Principles of Consolidation	The consolidated financial statements include our accounts and the accounts of our wholly and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates. To prepare financial statements in conformity with U.S. generally accepted accounting principles, management must make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and could have a material impact on our operating results and financial position.
Comparability	Comparability. Effective beginning of fiscal 2022, we adopted an Accounting Standards Update (ASU) to simplify the accounting for income taxes in Accounting Standards Codification (ASC) 740, Income Taxes, on a prospective basis. Effective beginning the second quarter of fiscal 2022, we early adopted an ASU, on a prospective basis, to apply revenue guidance to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination on the acquisition date, instead of measuring them at fair value. The adoption of these updates did not have a material impact on our consolidated financial statements. Effective beginning of fiscal 2021, we adopted ASC 326, Measurement of Credit Losses on Financial Instruments. Prior periods were not retrospectively recast and accordingly, the consolidated statements of income for the year ended October 31, 2020 were prepared using accounting standards that were different than those in effect for the years ended October 31, 2022 and 2021. Certain reclassifications have been made to the prior year's consolidated financial statements to conform to the current year presentation. The reclassifications did not have a material impact on the prior year's consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows.
Cash and Cash Equivalents and Short-term Investments	Cash and Cash Equivalents and Short-term Investments . We classify investments with original maturities of three months or less when acquired as cash equivalents. Our investments in debt securities with maturities of longer than three months from the consolidated balance sheets date are classified as short-term investments as we may convert these investments into cash at any time to fund general operations. Our debt securities generally have an effective maturity term of less than three years and are classified as available-for-sale securities carried at fair value, with unrealized gains and losses included in the consolidated balance sheets as a component of accumulated other comprehensive income (loss). For available-for-sale debt securities in an unrealized loss position, we evaluate whether a current expected credit loss exists based on available information relevant to the credit rating of the security, current economic conditions and reasonable and supportable forecasts. The allowance for credit loss is recorded in other income (expense), net, on the consolidated statements of income, not to exceed the amount of the unrealized loss. Any excess unrealized loss other than the credit loss is recognized in accumulated other comprehensive income or loss in the stockholders' equity section of the consolidated balance sheets. The cost of securities sold is based on the specific identification method and realized gains and losses are included in other income (expense), net. See Note 7. Financial Assets and Liabilitie
Accounts Receivable, Net	Accounts Receivable, Net. The balances consist of billed accounts receivable and current portion of unbilled accounts receivable. Trade accounts receivable are recorded at the invoiced amount and do not bear interest.
Allowance for Credit Losses	Allowance for Credit Losses. We maintain an allowance for credit losses for expected uncollectible accounts receivable and contract assets, which is recorded as an offset to accounts receivable or contract assets and provisions for credit losses are recorded in general and administrative expense in the consolidated statements of income. The allowance for current expected credit losses is based on a review of customer accounts and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance.
Inventories	Inventories. Inventories are computed at standard costs which approximate actual costs, on a first-in, first-out basis and valued at the lower of cost or net realizable value. Inventories primarily include components and finished goods for complex emulation and prototyping hardware systems. The valuation process includes a review of the forecasts based upon future demand and market conditions. Inventory provisions are recorded when the costs are determined to be in excess of anticipated demand or considered obsolete. Inventory provisions are impacted by market and economic conditions, technology changes, new product introductions and changes in strategic direction, and require estimates that may include uncertain elements.
Fair Values of Financial Instruments	Fair Values of Financial Instruments. Our cash equivalents, short-term investments and foreign currency contracts are carried at fair value. The fair value of our accounts receivable and accounts payable approximates the carrying amount due to their short duration. Non-marketable equity securities are accounted for using either the measurement alternative or equity method of accounting, net of impairments. We perform periodic impairment analysis on these non-marketable equity securities. The carrying amount of the short-term and long-term debt approximates the estimated fair value. See Note 8. Fair Value Measurements .
Foreign Currency Contracts	Foreign Currency Contracts. We operate internationally and are exposed to potentially adverse movements in currency exchange rates. We enter into hedges in the form of foreign currency forward contracts to reduce our exposure to foreign currency rate changes on non-functional currency denominated forecasted transactions and balance sheet positions. The assets or liabilities associated with the forward contracts are recorded at fair value in other current assets or accrued liabilities in the consolidated balance sheets. The accounting for gains and losses resulting from changes in fair value depends on the use of the foreign currency forward contract and whether it is designated and qualifies for hedge accounting. See Note 7. Financial Assets and Liabilities .
Concentration of Credit Risk	Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash equivalents, short-term investments, foreign currency contracts, and trade accounts receivable. We maintain cash equivalents primarily in highly rated taxable and tax-exempt money market funds located in the U.S. and in various overseas locations.
Income Taxes	Income Taxes. We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We account for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. An uncertain tax position is considered effectively settled on completion of an examination by a taxing authority if certain other conditions are satisfied.
Property and Equipment	Property and Equipment. Property and equipment is recorded at cost less accumulated depreciation. Assets, excluding land, are depreciated using the straight-line method over their estimated useful lives.
Investments in Equity Securities	Investments in Equity Securities. We hold equity securities in privately held companies for the promotion of business and strategic objectives. These investments are initially recorded at cost and included in other long-term assets in the consolidated balance sheets and are subject to a periodic impairment review. We account for these investments using the measurement alternative when the fair value of the investment is not readily determinable and we do not have the ability to exercise significant influence or using the equity method of accounting when it is determined that we have the ability to exercise significant influence. For investments accounted for using the equity method of accounting, we record our proportionate share of the investee’s income or loss to other income (expense), net, in our consolidated statements of income.
Leases	Leases . We determine if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to, and the agreement creates enforceable rights and obligations. A contract is or contains a lease when we have the right to control the use of an identified asset for a period of time. The commencement date of the lease is the date that the lessor makes an underlying asset available for use by the lessee. On the commencement date, leases are evaluated for classification and assets and liabilities are recognized based on the present value of lease payments over the lease term. The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The right of use (ROU) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments and any lease incentives. Variable lease payments, consisting primarily of reimbursement of costs incurred by lessors for common area maintenance, real estate taxes and insurance, are not included in the lease liability and are recognized as they are incurred. As most of our leases do not provide an implicit rate, we use the incremental borrowing rate at lease commencement to measure ROU assets and lease liabilities. We use a benchmark senior unsecured yield curve for debt instruments over the similar term, and consider specific credit quality, market conditions, tenor of lease arrangements, and quality of collateral to determine the incremental borrowing rate. Operating lease expense is generally recognized on a straight-line basis over the lease term. We have elected the practical expedient to account for the lease and non-lease components as a single lease component for the majority of our asset classes. For leases with an initial term of one year or less, we have elected not to record the ROU asset or liability.
Business Combination	Business Combinations. We allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed based on their acquisition-date fair values with the exception of contract assets and contract liabilities (deferred revenue) which are recognized and measured on the acquisition date in accordance with our “Revenue Recognition” policy. The excess of the fair value of purchase consideration over the fair value of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred. We include the results of operations of the businesses that are acquired from the acquisition date.
Goodwill	Goodwill. Goodwill represents the excess of the aggregate purchase price over the fair value of the net tangible and identifiable intangible assets acquired by us. The carrying amount of goodwill at each reporting unit is tested for impairment annually in the fourth fiscal quarter , or more frequently if facts and circumstances warrant a review.
Intangible Assets	Intangible Assets. Intangible assets consist of acquired technology, certain contract rights, customer relationships, trademarks and trade names, and capitalized software. These intangible assets are acquired through business combinations, direct purchases, or internally developed capitalized software. Intangible assets are amortized on a straight-line basis over their estimated useful lives which range from one
Redeemable Non-controlling Interest	Redeemable Non-controlling Interest. Non-controlling interest that is not solely redeemable within our control is reported as temporary equity in our consolidated balance sheets. The carrying value of the redeemable non-controlling interest equals the redemption value at the end of each reporting period, after giving effect to the change from the net income (loss) attributable to the redeemable non-controlling interest. We remeasure the redemption value of the non-controlling interest on a quarterly basis and changes in the estimated redemption value are recognized through retained earnings and may also impact the net income or loss attributable to common stockholders of Synopsys if the redemption value falls below a stated threshold. See Note 4. Business Combinations
Revenue Recognition	Revenue Recognition. We recognize revenue for the transfer of services or products to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those services or products. The principle is achieved through the following five-step approach: • Identification of the contract, or contracts, with the customer • Identification of the performance obligation in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, we satisfy a performance obligation Nature of Products and Services We generate revenue from the licensing of our EDA software, IP Blocks, and Software Integrity products, as well as sale of hardware products, and maintenance and services. The various types are set forth below. Electronic Design Automation Software license revenue consists of fees associated with the licensing of our software primarily through Technology Subscription License (TSL) contracts. TSLs are time-based licenses for a finite term and generally provide the customer with limited rights to receive, or to exchange certain quantities of licensed software for, unspecified future technology. The majority of our arrangements are TSLs due to the nature of our business and customer requirements. In addition to the licenses, the arrangements also include: post-contract customer support, which includes providing frequent updates and upgrades to maintain the utility of the software due to rapid changes in technology; other intertwined services such as multiple copies of the tools; assisting our customers in applying our technology in the customers' development environment; and rights to remix licenses for other licenses. Payments are generally received in equal or near equal installments over the term of the arrangement. We have concluded that our software licenses in TSL contracts are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term. Such updates represent inputs to a single, combined performance obligation, commencing upon the later of the arrangement effective date or transfer of control to 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 pattern of transfer to the customer over the duration of the subscription term. IP & System Integration We generally license IP under nonexclusive license agreements that provide usage rights for specific applications. Additionally, for certain IP license agreements, royalties are collected as customers sell their own products that incorporate our IP. These arrangements generally have two distinct performance obligations that consist of transferring the licensed IP and the post contract support service. Support services consist of a stand-ready obligation to provide technical support and software updates over the support term. Revenue allocated to the IP license is recognized at a point in time upon the later of the delivery date or the beginning of the license period, and revenue allocated to support services is recognized ratably over the support term. Royalties are recognized as revenue is earned, generally when the customer sells its products that incorporate our IP. Software Integrity Products Software Integrity product arrangements provide customers the right to software licenses, software updates and technical support. Under the term of these arrangements, the customer expects to receive integral updates to the software licenses that protect the customer’s software from potential security vulnerabilities. The licenses and software updates together serve to fulfill our commitment to the customer, as they represent inputs to a single, combined performance obligation that commences upon the later of the arrangement effective date or transfer of the software license. Software updates are part of the contract with the customer, and 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 We generally have two performance obligations in arrangements involving the sale of hardware products. The first performance obligation is to transfer the hardware product, which includes embedded software integral to the functionality of the hardware product. The second performance obligation is to provide maintenance on the hardware and our embedded software, including 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 portion of the transaction price allocated to the hardware product is recognized as revenue at a point in time when control of the hardware is transferred to the customer. We have concluded that control generally transfers upon shipment because the customer has the ability to direct the use of the asset and an obligation to pay for the hardware. The portion of the transaction price allocated to maintenance is recognized as revenue that is ratable over the maintenance term. Professional Services Our arrangements often include service elements (other than maintenance and support services). These services include training, design assistance, and consulting. These services are generally performed on a time and materials basis, and are recognized over time, as the customer simultaneously receives and consumes the benefit provided. Certain arrangements also include the customization or modification of licensed IP. Revenue from these contracts is recognized over time as the services are performed, when the development is specific to the customer’s needs and we have enforceable rights to payment for performance completed. Inputs such as costs incurred and hours expended are used in order to measure progress of performance. We have 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, specification and testing requirement changes, and changes in customer delivery priorities. Payments for services are generally due upon milestones in the contract or upon consumption of the hourly resources. Flexible Spending Accounts Our customers frequently enter into non-cancelable Flexible Spending Account arrangements (FSA) 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 our products or services. These arrangements do not meet the definition of a revenue contract until the customer executes a separate order (pulldown request) to identify the required products and services that they are purchasing. The combination of the FSA arrangement and the subsequent order creates enforceable rights and obligations, thus meeting the definition of a revenue contract. Each separate order under the agreement is treated as an individual contract and accounted for based on the respective performance obligations included within the pulldown requests. Significant Judgments Our contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether services and products are considered distinct performance obligations that should be accounted for separately versus together requires significant judgment . We have concluded that (1) our EDA software licenses in TSL contracts are not distinct from our obligation to provide unspecified software updates to the licensed software throughout the license term, because those promises represent inputs to a single, combined performance obligation, and (2) 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. In reaching this conclusion, we considered the nature of the obligation to customers which is to provide an ongoing right to use the most up to date and relevant software. As EDA customers operate in a rapidly changing and competitive environment, satisfying the obligation requires providing critical updates to the existing software products, including ongoing iterative interaction with customers to make the software relevant to customers’ ability to meet the time to go to market with advanced products. Similarly, we also concluded that in our Software Integrity business, the licenses and maintenance updates serve together to fulfill our commitment to the customer as both work together to provide the functionality to the customer and represent a combined performance obligation because the updates are essential to the software’s central utility, which is to identify security vulnerabilities and other threats. Our contracts with customers can involve hundreds of products and various license rights. Customers often negotiate a broad portfolio of solutions, and favorable terms along with future purchase options to manage their overall costs. Determining whether the purchase options are considered distinct performance obligations that should be accounted for separately as material rights versus combined together may require significant judgment. Judgment is also required to determine the standalone selling price (SSP) for each distinct performance obligation. For non-software performance obligations (IP, Hardware, and services), SSP is established based on observable prices of products and services sold separately. SSP for license (and related updates and support) in a contract with multiple performance obligations is determined by applying a residual approach whereby all other non-software performance obligations within a contract are first allocated a portion of the transaction price based upon their respective SSP, using observable prices, with any residual amount of the transaction price allocated to the license because we do not sell the license separately, and the pricing is highly variable. Contract Balances The timing of revenue recognition may differ from the timing of invoicing customers, and these timing differences result in receivables (billed or unbilled), contract assets, or contract liabilities (deferred revenue) on our consolidated balance sheet. We record a contract asset when revenue is recognized prior to the right to invoice, or deferred revenue when revenue is recognized subsequent to invoicing. For time-based software agreements, customers are generally invoiced in equal, quarterly amounts, although some customers prefer to be invoiced in single or annual amounts. We record an unbilled receivable when revenue is recognized and we have an unconditional right to invoice and receive payment.
Warranties and Indemnities	Warranties and Indemnities Warranties. We generally warrant our products to be free from defects in media and to substantially conform to material specifications for a period of 90 days for our software products and for up to six months for our hardware products.
Net Income Per Share	Net Income Per Share. We compute basic net income per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested restricted stock units and awards during the period using the treasury stock method. See Note 14. Net Income Per Share.
Foreign Currency Translation	Foreign Currency Translation. The functional currency of the majority of our active foreign subsidiaries is the foreign subsidiary’s local currency. Assets and liabilities that are not denominated in the functional currency are remeasured into the functional currency with any related gains or losses recorded in earnings. We translate assets and liabilities of our non-U.S. dollar functional currency foreign operations into the U.S. dollar reporting currency at exchange rates in effect at the balance sheet date. We translate income and expense items of such foreign operations into the U.S. dollar reporting currency at average exchange rates for the period. Accumulated translation adjustments are reported in stockholders’ equity, as a component of accumulated other comprehensive income (loss).
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (FASB) issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. We adopted the standard as of the beginning of fiscal 2022 on a prospective basis and the adoption did not have a material impact on our consolidated financial statements. Beginning in fiscal 2021, we adopted ASC 326, which was issued by the FASB in June 2016 as ASU 2016-13 Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments. The ASU replaced previous incurred loss impairment guidance and established a single expected credit losses allowance framework for financial assets carried at amortized cost. It also eliminated the concept of other-than-temporary impairment and requires credit losses related to certain available-for-sale debt securities to be recorded through an allowance for credit losses. We adopted ASC 326 using the modified retrospective method, which requires a cumulative-effect adjustment to the opening balance of retained earnings to be recognized on the date of adoption and, accordingly, recorded a net decrease of $3.2 million to retained earnings as of beginning of fiscal 2021. Please see the “Allowance for Credit Losses” accounting policy above. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if the acquirer had originated the contracts. We early adopted the standard in the second quarter of fiscal 2022 on a prospective basis, and the adoption did not have a material impact on our consolidated financial statements.

Fair Value Measurement	ASC 820-10, Fair Value Measurements and Disclosures , defines fair value, establishes guidelines and enhances disclosure requirements for fair value measurements. The accounting guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance also establishes a fair value hierarchy based on the independence of the source and objective evidence of the inputs used. There are three fair value hierarchies based upon the level of inputs that are significant to fair value measurement: Level 1 —Observable inputs that reflect quoted prices (unadjusted) for identical instruments in active markets; Level 2 —Observable inputs other than quoted prices included in Level 1 for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3 —Unobservable inputs to the valuation derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

[1]During fiscal 2022, we recognized stock-based compensation expense relating to restricted stock units, granted to senior executives in February, May and August 2022 with certain market, performance and service conditions (market-based RSUs). Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The performance period during which the achievement goals will be measured is fiscal 2022 and fiscal 2023. The maximum potential awards that may be earned are 187.5% of the target number of the initial awards. The awards will vest in equal increments in December 2023 and December 2024 if the TSR target, revenue growth metrics, and service conditions are achieved.

[1]During fiscal 2022, we recognized stock-based compensation expense relating to restricted stock units, granted to senior executives in February, May and August 2022 with certain market, performance and service conditions (market-based RSUs). Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The performance period during which the achievement goals will be measured is fiscal 2022 and fiscal 2023. The maximum potential awards that may be earned are 187.5% of the target number of the initial awards. The awards will vest in equal increments in December 2023 and December 2024 if the TSR target, revenue growth metrics, and service conditions are achieved.
