Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies and Basis of Presentation We have prepared the accompanying condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Pursuant to these rules and regulations, we have condensed or omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The condensed consolidated financial statements are unaudited but, in management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our quarterly results. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended October 31, 2022 as filed with the SEC on December 12, 2022 (our Annual Report). Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the condensed 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. Principles of Consolidation. The condensed 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. 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 2023 and 2022 are both 52-week years. Fiscal 2023 will end on October 28, 2023. Fiscal 2022 ended on October 29, 2022. For presentation purposes, the condensed consolidated financial statements and accompanying notes refer to the closest calendar month end. Comparability. Certain reclassifications have been made to the prior period's condensed consolidated financial statements to conform to the current year presentation. The reclassifications did not have a material impact on the prior period's condensed consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows. Segment Reporting. Effective in the first quarter of fiscal 2023, we realigned our organizational structure to evaluate the results of our Design IP business separately, and our Chief Operating Decision Maker (CODM), our Chief Executive Officer (CEO), now allocates resources and assesses performance against our key growth strategies based on this new organizational structure. As a result, we changed our reportable segments from two reportable segments to three reportable segments. The CODM now regularly reviews disaggregated information for the following three reportable segments: (1) Design Automation, which includes EDA tools, system integration solutions and other associated revenue categories, (2) Design IP, which includes IP products, and (3) Software Integrity, which includes a comprehensive solution for building integrity - security, quality and compliance testing - into the customers' software development lifecycle and supply chain. As such, prior period reportable segment results and related disclosures have been reclassified to reflect our current reportable segments. Goodwill. As a result of the change to our reportable segments, we reassessed our reporting units for the evaluation of goodwill during the first quarter of fiscal 2023. Prior to this change, our reporting units were determined to be the same as reportable segments for the purpose of goodwill impairment assessment. Our reassessment determined that we now have three reporting units, which are the same as our reportable segments. 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 on the first day of the fourth fiscal quarter, or more frequently if facts and circumstances warrant a review. We perform either a qualitative or quantitative assessment for goodwill impairment test. 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 loss is recorded for the difference. The change in reporting units was considered a triggering event, indicating a test for goodwill impairment was required before and after the change in reporting units. We performed those impairment tests, which did not result in the identification of an impairment loss as of January 31, 2023. If assumptions or estimates with respect to our future performance vary from what is expected, including but not limited to those assumptions relating to inflationary pressure on costs, geopolitical uncertainties and the threat of additional COVID-19 variants, this may impact the impairment analysis and could reduce the underlying cash flows used to estimate fair values and result in a decline in fair value that may trigger future impairment charges. Significant Accounting Policies. There have been no material changes to our significant accounting policies included in our Annual Report . Recently Issued Accounting Pronouncements In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (ASU 2022-03), which applies to all equity securities measured at fair value that are subject to contractual sale restrictions. This change prohibits entities from taking into account contractual restrictions on the sale of equity securities when estimating fair value and introduces required disclosures for such transactions. The standard will become effective for us beginning on November 1, 2024 and will be applied prospectively. Early adoption is permitted. Any future impact from the adoption of this guidance will depend on the facts and circumstances of future transactions.

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 condensed consolidated balance sheets. Contract balances were as follows: As of January 31, 2023 October 31, 2022 (in thousands) Contract assets, net $ 259,146 $ 260,498 Unbilled receivables $ 45,814 $ 46,254 Deferred revenue $ 2,167,871 $ 2,065,294 During the three months ended January 31, 2023, we recognized revenue of $793.5 million that was included in the deferred revenue balance as of October 31, 2022. Contracted but unsatisfied or partially unsatisfied performance obligations were approximately $6.9 billion as of January 31, 2023, which includes $1.0 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 January 31, 2023, excluding non-cancellable FSA, are expected to be recognized over the next 12 months, with the remainder recognized thereafter. During the three months ended January 31, 2023 and 2022, we recognized $24.7 million and $32.0 million, respectively, from performance obligations satisfied from sales-based royalties earned during the periods. Costs of Obtaining a Contract with Customer Capitalized commission costs, net of accumulated amortization, as of January 31, 2023 were $95.4 million and included in other long-term assets in our condensed consolidated balance sheets. Amortization of these assets was $18.9 million and $16.7 million during the three months ended January 31, 2023 and 2022, respectively, and included in sales and marketing expense in the condensed consolidated statements of income.

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 condensed 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 condensed consolidated balance sheets: As of January 31, 2023 October 31, 2022 (in thousands) Cash and cash equivalents $ 1,154,873 $ 1,417,608 Restricted cash included in prepaid and other current assets 1,658 1,566 Restricted cash included in other long-term assets 737 690 Total cash, cash equivalents and restricted cash $ 1,157,268 $ 1,419,864 Non-marketable equity securities. Our portfolio of non-marketable equity securities consists of strategic investments in privately held companies. There was an immaterial impairment of a non-marketable equity security during the three months ended January 31, 2023. There was no impairment of non-marketable equity securities during the three months ended January 31, 2022. Derivatives We recognize derivative instruments as either assets or liabilities in the condensed 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 condensed 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 condensed 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 during the three months ended January 31, 2023 and 2022. 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 the condensed consolidated statements of income were summarized as follows: Three Months Ended 2023 2022 (in thousands) Gains (losses) recorded in other income (expense), net $ 8,221 $ 446 The notional amounts in the table below for derivative instruments provided one measure of the transaction volume outstanding: As of January 31, 2023 October 31, 2022 (in thousands) Total gross notional amounts $ 1,317,911 $ 1,386,140 Net fair value $ (3,737) $ (50,080) Our exposure to 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.

Fair Value Measurements

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 of our 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 the 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 9. Credit and Term Loan Facilities for more information on these borrowings.

The Fifth Amendment increased the existing senior unsecured revolving credit facility (the Revolver) from $650.0 million to $850.0 million and extended the maturity date from January 22, 2024 to December 14, 2027, which could be further extended at our option. The Credit Agreement also provides an uncommitted incremental revolving loan facility of up to $150.0 million in the aggregate principal amount. The Credit Agreement contains a financial covenant requiring us to maintain a maximum consolidated leverage ratio, as well as other non-financial covenants. As of January 31, 2023, we were in compliance with the financial covenant. Borrowings bear interest at the adjusted term Secured Overnight Financing Rate (SOFR) plus an applicable margin between 0.785% and 0.975% based upon our consolidated leverage ratio. In addition, facility fees are payable on the Revolver at rates between 0.09% and 0.15% per year based on our leverage ratio on the daily amount of the revolving commitment. There was no outstanding balance under the Revolver as of January 31, 2023 and October 31, 2022. 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 January 31, 2023, we had $20.6 million outstanding balance under the agreement.

Stock Repurchase Program	Stock Repurchase Program In September 2022, our Board of Directors (the Board) approved a replenishment of our stock repurchase program (the Program) with authorization to purchase up to $1.5 billion of our common stock. In December 2022, we entered into an accelerated stock repurchase agreement (the December 2022 ASR) to repurchase an aggregate of $300.0 million of our common stock. Pursuant to the December 2022 ASR, we made a prepayment of $300.0 million to receive initial deliveries of shares valued at $255.0 million. The remaining balance of $45.0 million was settled in February 2023. Total shares purchased under the December 2022 ASR were approximately 0.9 million shares, at an average purchase price of $335.39 per share. During the three months ended January 31, 2023, we also repurchased on the open market approximately 18.2 thousand shares of our common stock at an average price of $314.77 per share for an aggregate purchase price of $5.7 million. As of January 31, 2023, $1.1 billion remained available for future repurchases under the Program.

Diluted net income per share reflects the dilution from potential common shares outstanding such as stock options and unvested RSUs and awards during the period using the treasury stock method. The table below reconciled the weighted average common shares used to calculate basic net income per share with the weighted average common shares used to calculate diluted net income per share: Three Months Ended 2023 2022 (in thousands, except per share amounts) Numerator: Net income attributed to Synopsys $ 271,536 $ 313,687 Denominator: Weighted average common shares for basic net income per share 152,401 153,218 Dilutive effect of common share equivalents 2,675 4,055 Weighted average common shares for diluted net income per share 155,076 157,273 Net income per share attributed to Synopsys: Basic $ 1.78 $ 2.05 Diluted $ 1.75 $ 1.99 Anti-dilutive employee stock-based awards excluded 527 170

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 CODM in deciding how to allocate resources and in assessing performance. Our CODM is our CEO. As described in Note 2, Summary of Significant Accounting Policies and Basis of Presentation , effective in the first quarter of fiscal 2023, we realigned our organizational structure to evaluate the results of our Design IP business separately, and our CODM now allocates resources and assesses performance against our key growth strategies based on this new organizational structure. As a result, we changed our reportable segments from two reportable segments to three reportable segments. Our three reportable segments are: (1) Design Automation, which includes EDA tools, system integration solutions and other associated revenue categories, (2) Design IP, which includes IP products, and (3) Software Integrity, which includes a comprehensive solution for building integrity - security, quality and compliance testing - into the customers’ software development lifecycle and supply chain. Prior period reportable segment results and related disclosures have been reclassified to reflect our current reportable segments. The financial information provided to and used by the CODM to assist in making operational decisions, allocating resources, and assessing performance includes consolidated financial information as well as revenue, adjusted operating income, and adjusted operating margin information for the Design Automation, Design IP and Software Integrity segments, accompanied by disaggregated information relating to revenue by geographic region. Information by reportable segment was as follows: Three Months Ended 2023 2022 (in thousands) Total Segments: Revenue $ 1,361,340 $ 1,270,255 Adjusted operating income 479,167 459,391 Adjusted operating margin 35 % 36 % Design Automation: Revenue $ 889,846 $ 803,862 Adjusted operating income 346,009 293,271 Adjusted operating margin 39 % 36 % Design IP: Revenue $ 343,651 $ 358,833 Adjusted operating income 117,625 154,121 Adjusted operating margin 34 % 43 % Software Integrity: Revenue $ 127,843 $ 107,560 Adjusted operating income 15,533 11,999 Adjusted operating margin 12 % 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, restructuring charges, 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: Three Months Ended 2023 2022 (in thousands) Total segment adjusted operating income $ 479,167 $ 459,391 Reconciling items: Amortization of intangible assets (25,357) (22,360) Stock-based compensation expense (134,227) (95,771) Deferred compensation plan (20,197) 19,599 Restructuring charges (40,859) (11,746) Other (2,595) (2,077) Total operating income $ 255,932 $ 347,036 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 related to operations in the United States and other geographic areas were: Three Months Ended 2023 2022 (in thousands) Revenue: United States $ 671,782 $ 610,334 Europe 135,007 132,717 China 197,778 212,823 Korea 145,792 114,355 Other 210,981 200,026 Consolidated $ 1,361,340 $ 1,270,255 Geographic revenue data for multi-regional, multi-product transactions reflect internal allocations and are therefore subject to certain assumptions and to our allocation methodology.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate We estimate our annual effective tax rate at the end of each fiscal quarter. The effective tax rate takes into account our estimations of annual pre-tax income, the geographic mix of pre-tax income and interpretations of tax laws and possible outcomes of audits. The following table presented the provision for income taxes and the effective tax rates: Three Months Ended 2023 2022 (in thousands) Income before income taxes $ 279,224 $ 327,243 Provision for income taxes $ 10,597 $ 13,902 Effective tax rate 3.8 % 4.2 % Our effective tax rate for the three months ended January 31, 2023 is lower than the statutory federal corporate tax rate of 21% primarily due to U.S. federal research tax credits, foreign-derived intangible income deduction, excess tax benefits from stock-based compensation, and U.S. foreign tax credits, partially offset by state taxes, the effect of non-deductible stock-based compensation, and higher taxes on certain foreign earnings. On December 22, 2017, the Tax Cuts and Jobs Act (Tax Act) was enacted, which significantly changed prior U.S. tax law and includes numerous provisions that affect our business. Effective our fiscal 2023, the Tax Act requires that research and development expenditures are capitalized and amortized instead of being deducted when incurred. Domestic research is capitalized over five years and foreign research is capitalized over fifteen years. For fiscal 2023, this will result in a significant increase to our cash tax liabilities and will also decrease our effective tax rate due to increasing the foreign derived intangible income deduction. The impact to our cash tax liabilities will decrease over time as the research and development expenditures are amortized. Our effective tax rate decreased in the three months ended January 31, 2023 as compared to the same period in fiscal 2022, primarily due to higher foreign derived intangible income deduction, as a result of the Tax Act, offset by lower excess tax benefits from stock-based compensation. 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 and $34 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 the 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. The next hearing has been scheduled for April 25, 2023. We are also under examination by the tax authorities in certain other jurisdictions. No material assessments have been proposed in these examinations. Legislative Developments On August 16, 2022, the Inflation Reduction Act of 2022 (the IR Act) was enacted in the United States. The IR Act includes a 15% minimum tax based primarily on global consolidated U.S. GAAP profits with a $1 billion minimum threshold. The tax takes effect in fiscal 2024, with the $1 billion threshold measured as an average over three years commencing in the current fiscal year. Computation of the tax includes adjustments which, among others, provide for an offset of income taxes paid or accrued in non-U.S. jurisdictions. The details of the computation will be subject to regulations to be issued by the U.S. Department of the Treasury. Synopsys will monitor regulatory developments and will continue to evaluate the impact, if any, of the minimum tax. The IR Act includes provisions intended to mitigate climate change by, among others, providing tax credit incentives for reductions in greenhouse gas emissions. The details of the implementation of these incentives are subject to regulations to be released by the U.S. Department of the Treasury. Synopsys is monitoring these developments and will continue to evaluate opportunities to utilize these incentives in the future. The IR Act imposes a 1% excise tax on the fair market value of stock repurchases made by covered corporations after December 31, 2022. The total taxable value of shares repurchased is reduced by the fair market value of any newly issued shares during the taxable year. We are assessing the potential impact of the stock repurchase excise tax. Based on our preliminary assessment, we do not expect a material impact on our overall capital allocation strategy or our consolidated financial statements. On August 9, 2022, the CHIPS and Science Act of 2022 (the CHIPS Act) was enacted in the United States. The CHIPS Act will provide financial incentives to the semiconductor industry which are primarily directed at manufacturing activities within the United States. We are evaluating potential opportunities related to the CHIPS Act.

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 our 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. Legal Settlement There have been no changes to the disclosure related to Mentor Graphics Corporation (now part of Siemens AG) since our Annual Report. See Note 10. Contingencies of our Annual Report for further information. 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, see Note 18. Income Taxes .

Summary of Significant Accoun_2

Summary of Significant Accounting Policies and Basis of Presentation (Policies)	3 Months Ended
	Jan. 31, 2023
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the condensed 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.
Principles of Consolidation	Principles of Consolidation. The condensed 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.
Fiscal Year End	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 2023 and 2022 are both 52-week years. Fiscal 2023 will end on October 28, 2023. Fiscal 2022 ended on October 29, 2022. For presentation purposes, the condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.
Comparability	Comparability. Certain reclassifications have been made to the prior period's condensed consolidated financial statements to conform to the current year presentation. The reclassifications did not have a material impact on the prior period's condensed consolidated balance sheets, statements of income, statements of comprehensive income and statements of cash flows.
Segment Reporting	Segment Reporting. Effective in the first quarter of fiscal 2023, we realigned our organizational structure to evaluate the results of our Design IP business separately, and our Chief Operating Decision Maker (CODM), our Chief
Goodwill	Goodwill. As a result of the change to our reportable segments, we reassessed our reporting units for the evaluation of goodwill during the first quarter of fiscal 2023. Prior to this change, our reporting units were determined to be the same as reportable segments for the purpose of goodwill impairment assessment. Our reassessment determined that we now have three reporting units, which are the same as our reportable segments. 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 on the first day of the fourth fiscal quarter, or more frequently if facts and circumstances warrant a review. We perform either a qualitative or quantitative assessment for goodwill impairment test. 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 loss is recorded for the difference. The change in reporting units was considered a triggering event, indicating a test for goodwill impairment was required before and after the change in reporting units. We performed those impairment tests, which did not result in the identification of an impairment loss as of January 31, 2023. If assumptions or estimates with respect to our future performance vary from what is expected, including but not limited to those assumptions relating to inflationary pressure on costs, geopolitical uncertainties and the threat of additional COVID-19 variants, this may impact the impairment analysis and could reduce the underlying cash flows used to estimate fair values and result in a decline in fair value that may trigger future impairment charges.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (ASU 2022-03), which applies to all equity securities measured at fair value that are subject to contractual sale restrictions. This change prohibits entities from taking into account contractual restrictions on the sale of equity securities when estimating fair value and introduces required disclosures for such transactions. The standard will become effective for us beginning on November 1, 2024 and will be applied prospectively. Early adoption is permitted. Any future impact from the adoption of this guidance will depend on the facts and circumstances of future transactions.
