Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Basis of Presentation	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, 2023 as filed with the SEC on December 12, 2023 (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 and Fiscal Quarter End. Our fiscal year 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 2024 is a 53-week year ending on November 2, 2024, which impacts our revenue, expenses and operating results. Fiscal 2023 was a 52-week year and ended on October 28, 2023. Our results of operations for the first six months of fiscal 2024 and 2023 included 27 weeks and 26 weeks, respectively, and ended on May 4, 2024 and April 29, 2023, respectively. For presentation purposes, the condensed consolidated financial statements and accompanying notes refer to the closest calendar month end. Software Integrity Divestiture. During the second quarter of fiscal 2024, we determined that our Software Integrity business met the criteria to be classified as a discontinued operation, and, as a result, Software Integrity’s historical financial results are reflected in our consolidated financial statements as discontinued operations, and assets and liabilities were retrospectively reclassified as assets and liabilities held for sale. We did not allocate any general corporate overhead to discontinued operations. See Note 3. Discontinued Operations of the Notes to Condensed Consolidated Financial Statements. 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 Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, 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 ASU 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 ASU will depend on the facts and circumstances of future transactions. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (CODM) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU is effective for our annual reports beginning in the fiscal year 2025, and interim period reports beginning in the first quarter of the fiscal year 2026 on a retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. The ASU will become effective for us beginning on November 1, 2025 and will be applied on a prospective ba sis, with a retrospective option. Early adoption is permitted.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations Pursuant to the Purchase Agreement, and subject to the satisfaction or waiver of customary closing conditions specified therein, we will sell our Software Integrity business to Buyer (the Software Integrity Divestiture) for a purchase price of up to $2.1 billion in cash, comprised of: (i) $1.5 billion, payable at closing; (ii) $125 million, payable in equal installments over five fiscal quarters beginning on the first business day after the day that is the 75th day of our first full fiscal quarter following the closing, subject to acceleration at our option prior to the closing of our pending acquisition of ANSYS, Inc. (Ansys); and (iii) up to $475 million, payable upon the Sponsors achieving a specified rate of return in the event of one or more potential liquidity transactions. The Software Integrity Divestiture, which was unanimously approved by our Board of Directors, is currently expected to close in the second half of 2024, subject to customary closing conditions including the receipt of required regulatory approvals. In accordance with the Accounting Standards Codification (ASC) 205-20-45-1B, management believes that the Software Integrity Divestiture has met the criteria to be disclosed as discontinued operations as it represents a significant strategic shift that has a major effect on our operations and financial results. The results of the Software Integrity business are presented as discontinued operations in the consolidated statements of income and, as such, have been excluded from both continuing operations and segment results for all periods presented. Further, we reclassified the assets and liabilities of Software Integrity business as assets and liabilities held for sale in the condensed consolidated statements of balance sheets for all periods presented. The condensed consolidated statements of cash flows are presented on a consolidated basis for both continuing operations and discontinued operations. We did not allocate any general corporate overhead to the Software Integrity business. Unless otherwise noted, reference within these Notes to Condensed Consolidated Financial Statements relates to continuing operations. The financial results of the Software Integrity business are presented as income from discontinued operations, net of income taxes on our condensed consolidated statements of income. The following table presents the major components of financial results of our Software Integrity business for the periods presented: Three Months Ended Six Months Ended 2024 2023 2024 2023 Revenue $ 126,421 $ 132,119 $ 264,662 $ 259,962 Cost of revenue 45,749 49,773 95,731 98,138 Operating expenses 89,626 87,389 170,891 167,558 Interest and other income (expense), net 340 41 996 398 Income (loss) from discontinued operations before income taxes (8,614) (5,002) (964) (5,336) Income tax provisions (benefits) (1,610) (2,310) (5,622) (4,496) Income (loss) from discontinued operations, net of income taxes $ (7,004) $ (2,692) $ 4,658 $ (840) As of April 30, 2024, the assets and liabilities of our Software Integrity business are classified as current in our condensed consolidated balance sheets, as it is probable that the sale will occur within one year.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Pending Acquisition of Ansys	Pending Acquisition of Ansys On January 15, 2024, we entered into an Agreement and Plan of Merger (the Merger Agreement) to acquire all of the outstanding shares of Ansys, a provider of broad engineering simulation and analysis software and services, in a cash-and-stock transaction (the Ansys Merger) that values Ansys at approximately $35.0 billion, based on the closing price of Synopsys common stock on December 21, 2023. Under the terms of the Merger Agreement, at the effective time of the Ansys Merger (the Effective Time), each share of Ansys common stock issued and outstanding immediately prior to the Effective Time (with certain exceptions set forth in the Merger Agreement) will be converted into the right to receive 0.3450 (the Exchange Ratio) of a share of Synopsys common stock and $197.00 in cash, without interest. The Merger Agreement also provides for Synopsys’ assumption of certain outstanding Ansys options and other unvested Ansys equity awards held by continuing Ansys employees. If the stock consideration to be issued by Synopsys in connection with the Ansys Merger would exceed 19.9999% of the shares of Synopsys common stock issued and outstanding immediately prior to the Effective Time, the Exchange Ratio will be reduced to the minimum extent necessary to ensure that the aggregate number of shares of Synopsys common stock to be issued in connection with the Ansys Merger does not exceed such threshold, and the cash consideration will be correspondingly increased to offset such adjustment. The Ansys Merger was approved by the holders of a majority of the outstanding shares of Ansys common stock on May 22, 2024 and is anticipated to close in the first half of calendar year 2025. The Ansys Merger is subject to the satisfaction or waiver of customary closing conditions, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, the clearance of the Ansys Merger under certain other antitrust and foreign investment regimes, and the continued effectiveness of the registration statement on Form S-4 (File No. 333-277912) filed by us on March 14, 2024 and declared effective by the SEC on April 17, 2024. We and Ansys each have termination rights under the Merger Agreement. A fee of $1.5 billion may be payable by us to Ansys, or a fee of $950.0 million may be payable by Ansys to us, upon termination of the Merger Agreement under specified circumstances, each as more fully described in the Merger Agreement. In connection with the execution of the Merger Agreement, we entered into a commitment letter on January 15, 2024 (the Bridge Commitment Letter) with certain financial institutions that committed to provide, subject to the satisfaction of customary closing conditions, a senior unsecured bridge facility (the Bridge Commitment). The Bridge Commitment currently provides for an aggregate principal amount of up to $11.7 billion. On February 13, 2024 , we entered into a term loan facility credit agreement (the Term Loan Agreement), which provides us with the ability to borrow up to $4.3 billion at the closing of the Ansys Merger, subject to the satisfaction of customary closing conditions for similar facilities, for the purpose of financing a portion of the cash consideration to be paid in the Ansys Merger and paying related fees and expenses in connection with the Ansys Merger and the other transactions contemplated by the Merger Agreement. See Note 11. Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Condensed Consolidated Financial Statements for more information on the Bridge Commitment and the Term Loan Agreement. During the six months ended April 30, 2024, we completed two acquisitions for aggregate purchase consideration of $139.5 million, net of cash acquired. The purchase consideration was allocated as follows: $71.7 million to identifiable intangible assets, $82.7 million to goodwill, and $14.9 million to net tangible liabilities. The total purchase consideration is preliminary, and as additional information becomes available, we may further revise it during the remainder of the measurement period, which will not exceed 12 months from the closing of the acquisition. The goodwill recognized from these acquisitions, of which $47.9 million was attributable to the Design Automation reporting unit and $34.8 million was attributable to the Design IP reporting unit, was not deductible for income tax purposes. We have included the financial results of these acquisitions in our condensed consolidated financial statements from the date of each acquisition. These results were not material to our condensed consolidated financial statements. Transaction costs were $25.3 million and $57.2 million during the three and six months ended April 30, 2024, respectively . Transaction costs were $2.6 million and $5.0 million during the three and six months ended April 30, 2023, respectively. These costs mainly consisted of professional fees and administrative costs for closed and pending acquisitions and were expensed as incurred in our condensed consolidated statements of income.

The following table provides a reconciliation of cash, cash equivalents and restricted cash included in the condensed consolidated balance sheets and the condensed consolidated statements of cash flows: As of April 30, 2024 October 31, 2023 (in thousands) Cash and cash equivalents $ 1,502,920 $ 1,433,966 Restricted cash included in prepaid and other current assets 1,557 1,549 Restricted cash included in other long-term assets 722 725 Cash, cash equivalents and restricted cash $ 1,505,199 $ 1,436,240 Cash, cash equivalents and restricted cash from discontinued operations 6,445 4,947 Total cash, cash equivalents and restricted cash, including cash from discontinued operations $ 1,511,644 $ 1,441,187 Non-marketable equity securities. Our portfolio of non-marketable equity securities consists of strategic investments in privately held companies. In November 2023, we completed the sale of strategic investments in privately-held companies. The gain recognized from the sales was $55.1 million and included in interest and other income (expense), net, in our condensed consolidated statements of income. There were no material impairments of non-marketable equity securities during the three and six months ended April 30, 2024 and 2023. 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 4 months to 28 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 28 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 six months ended April 30, 2024 and 2023. 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 interest and 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 interest and 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 interest and 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 are summarized as follows: Three Months Ended Six Months Ended 2024 2023 2024 2023 (in thousands) Gains (losses) recorded in Interest and other income (expense), net $ (4,355) $ (3,484) $ (1,066) $ 4,737 The notional amounts in the table below for derivative instruments provide one measure of the transaction volume outstanding: As of April 30, 2024 October 31, 2023 (in thousands) Total gross notional amounts $ 1,759,952 $ 1,666,758 Net fair value $ 8,824 $ (2,308) 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 represents the condensed 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 April 30, 2024 Other current assets $ 18,349 $ 634 Accrued liabilities $ 8,924 $ 1,235 Balance at October 31, 2023 Other current assets $ 12,962 $ 491 Accrued liabilities $ 14,665 $ 1,096 The following table represents the location of the amount of gains and losses on derivative instrument fair values for designated hedge instruments, net of tax in the condensed consolidated statements of income: Location of Amount of Location of Amount of (in thousands) Three months ended Foreign exchange contracts Revenue $ (2,507) Revenue $ (1,019) Foreign exchange contracts Operating expenses (4,628) Operating expenses (137) Total $ (7,135) $ (1,156) Three months ended Foreign exchange contracts Revenue $ 1,149 Revenue $ (5,537) Foreign exchange contracts Operating expenses (5,679) Operating expenses (3,737) Total $ (4,530) $ (9,274) Six months ended Foreign exchange contracts Revenue $ (2,565) Revenue $ (4,282) Foreign exchange contracts Operating expenses 6,040 Operating expenses (152) Total $ 3,475 $ (4,434) Six months ended Foreign exchange contracts Revenue $ 6,416 Revenue $ (9,504) Foreign exchange contracts Operating expenses 31,166 Operating expenses (8,127) Total $ 37,582 $ (17,631)

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 for identical instruments in active markets, quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in inactive markets, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3 —Unobservable inputs 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 11. Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Condensed Consolidated Financial Statements for more information on these borrowings. Assets/Liabilities Measured at Fair Value on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis are summarized below as of April 30, 2024: Fair Value Measurement Using Description Total Quoted Prices in Significant Other Significant (in thousands) Assets Cash equivalents: Money market funds $ 46,938 46,938 $ — $ — U.S. Treasury, agency & T-bills — — — — Short-term investments: U.S. Treasury, agency & T-bills 18,698 — 18,698 — Municipal bonds 511 — 511 — Corporate debt securities 104,385 — 104,385 — Asset-backed securities 33,186 — 33,186 — Prepaid and other current assets: Foreign currency derivative contracts 18,983 — 18,983 — Other long-term assets: Deferred compensation plan assets 349,016 349,016 — — Total assets $ 571,717 $ 395,954 $ 175,763 $ — Liabilities Accounts payable and accrued liabilities: Foreign currency derivative contracts $ 10,159 $ — $ 10,159 $ — Other long-term liabilities: Deferred compensation plan liabilities 349,016 349,016 — — Total liabilities $ 359,175 $ 349,016 $ 10,159 $ — Assets and liabilities measured at fair value on a recurring basis are summarized below as of October 31, 2023: Fair Value Measurement Using Description Total Quoted Prices in Significant Other Significant (in thousands) Assets Cash equivalents: Money market funds $ 10,129 $ 10,129 $ — $ — U.S. Treasury, agency & T-bills 2,994 — 2,994 — Short-term investments: U.S. Treasury, agency & T-bills 15,689 — 15,689 — Municipal bonds 499 — 499 — Corporate debt securities 102,375 — 102,375 — Asset-backed securities 33,076 — 33,076 — Prepaid and other current assets: Foreign currency derivative contracts 13,453 — 13,453 — Other long-term assets: Deferred compensation plan assets 297,180 297,180 — — Total assets $ 475,395 $ 307,309 $ 168,086 $ — Liabilities Accounts payable and accrued liabilities: Foreign currency derivative contracts $ 15,761 $ — $ 15,761 $ — Other long-term liabilities: Deferred compensation plan liabilities 297,180 297,180 — — Total liabilities $ 312,941 $ 297,180 $ 15,761 $ — Assets/Liabilities Measured at Fair Value on a Non-Recurring Basis Non-Marketable Equity Securities Non-marketable equity securities are classified within Level 3 as they are valued using a combination of observable transaction price and unobservable inputs or data in an inactive market due to the absence of market price and inherent lack of liquidity.

Debt Disclosure [Abstract]
Bridge Commitment Letter, Term Loan and Revolving Credit Facilities	Bridge Commitment Letter, Term Loan and Revolving Credit Facilities On January 15, 2024, we entered into the Bridge Commitment Letter with certain financial institutions that committed to provide, subject to the satisfaction of customary closing conditions, the Bridge Commitment. The Bridge Commitment currently provides for an aggregate principal amount of up to $11.7 billion. The proceeds of any borrowing under the Bridge Commitment will be used for the purpose of financing a portion of the cash consideration to be paid in the Ansys Merger and paying related fees and expenses in connection with the Ansys Merger and the other transactions contemplated by the Merger Agreement. The commitments to provide the Bridge Commitment may be terminated in whole or reduced in part, at our discretion. In addition, the Bridge Commitment Letter provides that net cash proceeds received from certain debt and equity issuances or the sale of certain businesses and assets, including the pending Software Integrity Divestiture, as well as term loan commitments under certain qualifying term loan facilities, will result in mandatory commitment reductions under the Bridge Commitment. On February 13, 2024, we entered into the Term Loan Agreement in connection with the financing of the pending Ansys Merger. The Term Loan Agreement provides us with the ability to borrow up to $4.3 billion at the closing of the Ansys Merger, subject to the satisfaction of customary closing conditions for similar facilities, for the purpose of financing a portion of the cash consideration to be paid in the Ansys Merger and paying related fees and expenses in connection with the Ansys Merger and the other transactions contemplated by the Merger Agreement. The Term Loan Agreement provides for two tranches of senior unsecured term loans: a $1.45 billion tranche (Tranche 1) that matures two years after funding and a $2.85 billion tranche (Tranche 2) that matures three years after funding. There was no outstanding balance under the Term Loan Agreement as of April 30, 2024. The Term Loan Agreement contains a financial covenant requiring that Synopsys maintain a maximum consolidated leverage ratio commencing the last day of the first fiscal quarter ending on or after the completion of the Ansys Merger, as well as other non-financial covenants. Under the Term Loan Agreement, borrowings will bear interest on the principal amount outstanding at a floating rate based on, at Synopsys’ election, (i) the Adjusted Term SOFR Rate (as defined in the Term Loan Agreement) plus an applicable margin based on the credit ratings of Synopsys ranging from 0.875% to 1.375% (in the case of Tranche 1) or 1.000% to 1.500% (in the case of Tranche 2) or (ii) the ABR (as defined in the Term Loan Agreement) plus an applicable margin based on the credit ratings of Synopsys ranging from 0.000% to 0.375% (in the case of Tranche 1) or 0.000% to 0.500% (in the case of Tranche 2). We will also pay a ticking fee under the Term Loan Agreement in an amount equal to a rate per annum equal to 0.10% times the actual daily undrawn portion of the commitments in respect of the term loan facility, from and including May 14, 2024 to but excluding the earlier of (i) termination or expiration of the commitments under the term loan facility or (ii) the funding of the commitments. On February 13, 2024, we entered into a Sixth Amendment Agreement (the Sixth Amendment), which amended and restated our previous revolving credit agreement, dated as of December 14, 2022 (as amended and restated, the Revolving Credit Agreement). The Revolving Credit Agreement provides an unsecured $850.0 million committed multicurrency revolving credit facility and an unsecured uncommitted incremental revolving loan facility of up to $150.0 million. The maturity date of the revolving credit facility is December 14, 2027, which may be extended at our option. Under the Sixth Amendment, certain amendments became effective on February 13, 2024 and certain additional amendments will become effective upon the completion of the Ansys Merger. Upon the effective date, the Sixth Amendment amended the financial covenant to allow netting of the cash proceeds of certain debt incurred to finance the Ansys Merger as well as certain other modifications set forth therein. Upon the completion of the Ansys Merger, the Sixth Amendment, among other things: (i) amends the applicable margin used to determine the interest that accrues on loans and the facility fee payable under the revolving credit facility to be based on our credit ratings, (ii) amends the financial covenant thresholds under the financial covenant in the Revolving Credit Agreement requiring us to maintain a maximum consolidated leverage ratio and (iii) amends certain conditions to borrowing, other non-financial covenants and events of default. The Revolving Credit Agreement contains a financial covenant requiring us to maintain a maximum consolidated leverage ratio, as well as other non-financial covenants. As of April 30, 2024, we were in compliance with the financial covenant. Interest accrues on dollar-denominated loans at a floating rate based on, at Synopsys’ election, (i) the Adjusted Term SOFR Rate (as defined in the Revolving Credit Agreement) plus an applicable margin or (ii) the ABR (as defined in the Revolving Credit Agreement) plus an applicable margin. The applicable margin for Adjusted Term SOFR Rate based loans ranges from 0.785% to 0.975%, based upon Synopsys’ consolidated leverage ratio. The applicable margin for ABR based loans is 0.000%. In addition to the interest on any outstanding loans, Synopsys is also required to pay a facility fee on the entire portion of the revolving credit facility ranging from 0.09% to 0.15% based on Synopsys’ consolidated leverage ratio on the daily amount of the revolving commitment. Subject to the completion of the Ansys Merger, interest under the Revolving Credit Agreement will accrue on dollar-denominated loans at a floating rate based on, at Synopsys’ election, (i) the Adjusted Term SOFR Rate plus an applicable margin based on our credit ratings ranging from 0.795% to 1.200% or (ii) the ABR plus an applicable margin based on our credit ratings ranging from 0.000% to 0.200%. In addition to the interest on any outstanding loans, Synopsys will also be required to pay a facility fee on the entire portion of the revolving credit facility ranging from 0.080% to 0.175% based on the credit ratings of Synopsys on the daily amount of the revolving commitment. There was no outstanding balance under the Revolving Credit Agreement as of April 30, 2024 and October 31, 2023. 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 April 30, 2024, we had $17.0 million outstanding balance under the agreement. The carrying amount of the short-term and long-term debt approximates the estimated fair value.

Noncontrolling Interest [Abstract]
Redeemable Non-controlling Interest	Redeemable Non-controlling Interest During the second quarter of fiscal 2022, we acquired a 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 (1) at the option of the Minority Investor on or after the third anniversary of the acquisition or sooner in certain circumstances or (2) 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. During the six months ended April 30, 2024 , our ownership interest in OpenLight was reduced to 71% as a result of the recognition of non-controlling interest upon issuance of OpenLight stock. During the six months ended April 30, 2024, OpenLight incurred a net loss of $19.0 million, of which $4.6 million was attributable to redeemable non-controlling interest. As of April 30, 2024, the carrying value of the redeemable non-controlling interest was recorded at its estimated fair value of $31.0 million in the condensed consolidated balance sheets.

Diluted net income (loss) 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 reconciles the weighted average common shares used to calculate basic net income (loss) per share with the weighted average common shares used to calculate diluted net income (loss) per share: Three Months Ended Six Months Ended 2024 2023 2024 2023 (in thousands, except per share amounts) Numerator: Net income from continuing operations attributed to Synopsys $ 299,111 $ 275,602 $ 736,561 $ 545,286 Net income (loss) from discontinued operations attributed to Synopsys (7,004) (2,692) 4,658 (840) Net income attributed to Synopsys $ 292,107 $ 272,910 $ 741,219 $ 544,446 Denominator: Weighted average common shares for basic net income per share 152,971 152,187 152,629 152,294 Dilutive effect of common share equivalents from equity-based compensation 2,799 2,543 2,981 2,750 Weighted average common shares for diluted net income per share 155,770 154,730 155,610 155,044 Net income (loss) per share attributed to Synopsys - basic: Continuing operations $ 1.96 $ 1.81 $ 4.83 $ 3.58 Discontinued operations $ (0.05) $ (0.02) $ 0.03 $ (0.01) Basic net income per share $ 1.91 $ 1.79 $ 4.86 $ 3.57 Net income (loss) per share attributed to Synopsys - diluted: Continuing operations $ 1.92 $ 1.78 $ 4.73 $ 3.52 Discontinued operations $ (0.04) $ (0.02) $ 0.03 $ (0.01) Diluted net income per share $ 1.88 $ 1.76 $ 4.76 $ 3.51 Anti-dilutive employee stock-based awards excluded 208 480 202 402

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. We have two reportable segments: (1) Design Automation, which includes our advanced silicon design, verification products and services, system integration products and services, digital, custom and field programmable gate array (FPGA) IC design software, verification software and hardware products, manufacturing software products and other; and (2) Design IP, which includes our Design IP products. 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 and Design IP segments, accompanied by disaggregated information relating to revenue by geographic region. In accordance with applicable accounting guidance, the results of the Software Integrity business are presented as discontinued operations in the condensed consolidated statements of income and, as such, have been excluded from both continuing operations and segment results for all periods presented. See Note 3. Discontinued Operations of the Notes to Condensed Consolidated Financial Statements . Information by reportable segment is as follows: Three Months Ended Six Months Ended 2024 2023 2024 2023 (in thousands) Total Segments: Revenue $ 1,454,712 $ 1,262,744 $ 2,965,701 $ 2,496,241 Adjusted operating income 543,042 434,981 1,148,234 887,746 Adjusted operating margin 37 % 34 % 39 % 36 % Design Automation: Revenue $ 1,054,933 $ 927,568 $ 2,040,272 $ 1,817,414 Adjusted operating income 418,245 353,439 777,710 692,814 Adjusted operating margin 40 % 38 % 38 % 38 % Design IP: Revenue $ 399,779 $ 335,176 $ 925,429 $ 678,827 Adjusted operating income 124,797 81,542 370,524 194,932 Adjusted operating margin 31 % 24 % 40 % 29 % 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 acquired intangible assets, stock-based compensation, changes in the fair value of deferred compensation plan, restructuring charges, and acquisition/divestiture related items, are presented in the table below to provide a reconciliation of the total adjusted operating income from segments to our consolidated operating income from continuing operations: Three Months Ended Six Months Ended 2024 2023 2024 2023 (in thousands) Total segment adjusted operating income $ 543,042 $ 434,981 $ 1,148,234 $ 887,746 Reconciling items: Amortization of acquired intangible assets (18,061) (12,392) (34,745) (25,624) Stock-based compensation expense (162,691) (130,360) (328,196) (252,958) Deferred compensation plan (11,051) (2,791) (50,496) (22,631) Restructuring charges — 5,578 — (32,560) Acquisition/divestiture related items (19,167) (2,641) (50,099) (4,975) Total operating income $ 332,072 $ 292,375 $ 684,698 $ 548,998 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 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 are: Three Months Ended Six Months Ended 2024 2023 2024 2023 (in thousands) Revenue: United States $ 630,766 $ 582,485 $ 1,354,587 $ 1,171,607 Europe 147,476 134,067 284,746 251,298 China 221,820 190,044 462,884 381,496 Korea 192,676 154,374 374,721 297,536 Other 261,974 201,774 488,763 394,304 Consolidated $ 1,454,712 $ 1,262,744 $ 2,965,701 $ 2,496,241 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 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 presents the provision for income taxes and the effective tax rates: Three Months Ended Six Months Ended 2024 2023 2024 2023 (in thousands) Income before income taxes $ 341,530 $ 296,587 $ 798,984 $ 576,145 Provision (benefit) for income taxes $ 45,437 $ 23,947 $ 68,346 $ 36,730 Effective tax rate 13.3 % 8.1 % 8.6 % 6.4 % Our effective tax rate for the six months ended April 30, 2024, 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 and the effect of non-deductible stock-based compensation. Our effective tax rate increased in the three and six months ended April 30, 2024, as compared to the same periods in fiscal 2023, primarily due to a reduced benefit from U.S. federal research tax credits, increase in foreign tax and partially offset by increased 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 $5.4 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 fiscal 2018, Synopsys Hungary paid the assessment. Following years of litigation, the Administrative Court issued its written decision in favor of Synopsys Hungary on May 17, 2023, and the HTA subsequently refunded Synopsys Hungary the tax, penalty and interest paid in fiscal 2018, as well as additional interest totaling $39.1 million (including foreign currency effects). During the third quarter of fiscal 2023, we released our unrecognized tax benefit and offsetting U.S. foreign tax credits, resulting in a net benefit of $23.8 million. We are also under examination by the tax authorities in certain other jurisdictions. No material assessments have been proposed in these examinations. Legislative Developments Effective our fiscal 2024, we are subject to the new 15% corporate alternative minimum tax (CAMT) enacted as part of the Inflation Reduction Act of 2022. We do not expect any impact of CAMT in fiscal 2024. On January 31, 2024, the House of Representatives has passed the Tax Relief for American Families and Workers Act of 2024 (H.R. 7024) which would defer the requirement of capitalizing research and development, based in the United States, until tax years starting after December 31, 2025. The proposed legislation would have a beneficial impact on our cash tax liabilities, if enacted. We will continue to monitor the status of this legislation.

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 the Notes to Consolidated Financial Statements in 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 20. Income Taxes of the Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

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 and Fiscal Quarter End	Fiscal Year and Fiscal Quarter End. Our fiscal year 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 2024 is a 53-week year ending on November 2, 2024, which impacts our revenue, expenses and operating results. Fiscal 2023 was a 52-week year and ended on October 28, 2023. Our results of operations for the first six months of fiscal 2024 and 2023 included 27 weeks and 26 weeks, respectively, and ended on May 4, 2024 and April 29, 2023, respectively. For presentation purposes, the condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.
Software Integrity Divestiture	Software Integrity Divestiture.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, 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 ASU 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 ASU will depend on the facts and circumstances of future transactions. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (CODM) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU is effective for our annual reports beginning in the fiscal year 2025, and interim period reports beginning in the first quarter of the fiscal year 2026 on a retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. The ASU will become effective for us beginning on November 1, 2025 and will be applied on a prospective ba sis, with a retrospective option. Early adoption is permitted.
