Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Basis of Presentation The accompanying interim condensed consolidated financial statements have been prepared in conformity with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X, and should be read in conjunction with the Xilinx, Inc. (Xilinx or the Company) consolidated financial statements filed with the U.S. Securities and Exchange Commission (SEC) on Form 10-K for the fiscal year ended March 28, 2020. The interim financial statements are unaudited, but reflect all adjustments which are, in the opinion of management, of a normal, recurring nature necessary to provide a fair statement of results for the interim periods presented. The results of operations for the interim periods shown in this report are not necessarily indicative of the results that may be expected for the fiscal year ending April 3, 2021 or any future period. The Company uses a 52- to 53-week fiscal year ending on the Saturday nearest March 31. Fiscal 2021 and fiscal 2020 are 53-week and 52-week years ending on April 3, 2021 and March 28, 2020, respectively. The quarter ended January 2, 2021 consisted of 14 weeks. The quarter ended December 28, 2019 consisted of 13 weeks. Merger with Advanced Micro Devices, Inc. On October 27, 2020, the Company announced that it had entered into an Agreement and Plan of Merger, dated October 26, 2020 (as it may be amended from time to time, the Merger Agreement) with Advanced Micro Devices, Inc., a Delaware corporation (AMD), and Thrones Merger Sub, Inc., a wholly-owned subsidiary of AMD (Merger Sub), under which, subject to the satisfaction or (to the extent permissible) waiver of the conditions set forth therein, Merger Sub will merge with and into the Company, and the Company will survive the merger as a wholly-owned subsidiary of AMD (Merger). Under the terms of the Merger Agreement, at the effective time of the Merger (Effective Time), each share of common stock, par value $0.01 per share, of the Company, issued and outstanding immediately prior to the Effective Time (other than treasury shares and any shares of Company common stock held by AMD or Merger Sub) will be converted into the right to receive 1.7234 fully paid and non-assessable shares of common stock, par value $0.01 per share, of AMD (with cash being paid, without interest and less applicable withholding taxes, in lieu of any fractional shares of AMD common stock). The Merger has been approved by both the Company’s board of directors and the board of directors of AMD. The completion of the Merger is subject to customary closing conditions, including, among others, the approvals of the Company’s stockholders and AMD’s stockholders and the receipt of various regulatory approvals. Subject to the satisfaction or (to the extent permissible) waiver of such conditions, the Merger is currently expected to close by the end of calendar year 2021. The Company cannot guarantee that the Merger will be completed on a timely basis or at all or that, if completed, it will be completed on the terms set forth in the Merger Agreement. The aggregate financial advisor fees associated with the Merger are $90.0 million in total, $9.0 million of which was paid upon the public announcement of the Merger, and the remainder is contingent upon the closing of the Merger. The Company is also obligated to pay up to an additional $40.0 million calculated based on the extent to which the value of the Company’s shares in the Merger at the time of closing exceeds a specified threshold. If the Merger is not completed, the Company could be required to pay a termination fee of $1.00 billion to AMD under certain circumstances as described in the Merger Agreement.

Recent Accounting Changes and A

Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Error Corrections [Text Block]	Recent Accounting Changes and Accounting Pronouncements Recent Accounting Pronouncements Adopted Credit Losses In June 2016, the Financial Accounting Standards Board (FASB) issued authoritative guidance to replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance requires a forward-looking expected credit loss model for financial assets, including accounts receivable and available for sale debt securities. The Company adopted this authoritative guidance in the first quarter of fiscal 2021 and the impact of the adoption was not material to the Company's condensed consolidated financial statements. Goodwill In January 2017, the FASB issued authoritative guidance that simplifies the accounting for goodwill impairment. The authoritative guidance removes Step 2 of the goodwill impairment test, which required a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The Company adopted this authoritative guidance in the first quarter of fiscal 2021 and the adoption did not impact the Company's condensed consolidated financial statements. Cloud Computing Arrangements In August 2018, the FASB issued new guidance requiring a customer in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs related to a hosting arrangement that is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. The Company adopted this authoritative guidance in the first quarter of fiscal 2021 and the impact of the adoption was not material to the Company's condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted Income Taxes In December 2019, the FASB issued authoritative guidance that simplifies the accounting for income taxes as part of the overall initiative to reduce complexity in accounting standards. Amendments include removal of certain exceptions to the general principles of Accounting Standards Codification 740, Income Taxes. The amendments also include simplification in several other areas, such as recognition of deferred tax assets on step-up in tax basis in goodwill and accounting for franchise tax that is partially based on income. For public entities, the guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, which for Xilinx would be the first quarter of fiscal 2022. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company has decided not to early adopt this new authoritative guidance and is currently evaluating the impact of this authoritative guidance on its consolidated financial statements.

Significant Customers and Concentrations of Credit Risk [Abstract]
Concentration Risk Disclosure [Text Block]	Significant Customers and Concentrations of Credit Risk Avnet, Inc. (Avnet), one of the Company’s distributors, distributes the Company’s products worldwide. As of January 2, 2021 and March 28, 2020, Avnet accounted for 34% and 31% of the Company’s total net accounts receivable, respectively. Net revenues from Avnet accounted for 44% and 43% of the Company’s worldwide net revenues in the third quarter and the first nine months of fiscal 2021, respectively. Net revenues from Avnet accounted for 45% and 41% of the Company’s worldwide net revenues in the third quarter and the first nine months of fiscal 2020. While the percentage of worldwide net revenues from Avnet fluctuates from period to period, overall the percentage is within historical ranges. For the third quarter and the first nine months of fiscal 2021, approximately 56% and 57% of the Company's net revenues were from products sold to distributors for subsequent resale to original equipment manufacturers (OEMs) or their subcontract manufacturers, respectively. For the third quarter and the first nine months of fiscal 2020, the percentages of the Company's net revenues from distributors were 57% and 52%, respectively. No other distributor or end customer accounted for more than 10% of the Company’s worldwide net revenues for the third quarter and the first nine months of fiscal 2021. No other distributor accounted for more than 10% of the Company’s worldwide net revenues for the third quarter and the first nine months of fiscal 2020. However, one end customer accounted for 12% and 11% of the Company's worldwide net revenues for the third quarter and the first nine months of fiscal 2020, respectively. Xilinx is subject to concentrations of credit risk primarily in its trade accounts receivable and investments in debt securities to the extent of the amounts recorded on the condensed consolidated balance sheet. The Company attempts to mitigate the concentrations of credit risk in its trade receivables through its credit evaluation process, collection terms, distributor sales to diverse end customers and through geographical dispersion of sales. Xilinx generally does not require collateral for receivables from its end customers or distributors. The Company mitigates concentrations of credit risk in its investments in debt securities by currently investing approximately 96% of its portfolio in AA (or its equivalent) or higher-grade securities as rated by Standard & Poor’s or Moody’s Investors Service. The Company’s methods to arrive at investment decisions are not solely based on the rating agencies’ credit ratings. Xilinx also performs additional credit due diligence and conducts regular portfolio credit reviews, including a review of counterparty credit risk related to the Company’s forward currency exchange contracts. Additionally, Xilinx limits its investments in the debt securities of a single issuer based upon the issuer’s credit rating and attempts to further mitigate credit risk by diversifying risk across geographies and type of issuer. As of January 2, 2021, all of the mortgage-backed securities in the Company's investment portfolio were issued by U.S. government-sponsored enterprises and agencies and are rated AA+ by Standard & Poor’s and Aaa by Moody’s Investors Service.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The authoritative guidance for fair value measurements established by the FASB defines fair value as the exchange price that would be received from selling an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which Xilinx would transact and also considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions and risk of nonperformance. The Company determines the fair value for marketable debt securities using industry standard pricing services, data providers and other third-party sources and by internally performing valuation testing and analysis. The Company primarily uses a consensus price or weighted-average price for its fair value assessment. The Company determines the consensus price using market prices from a variety of industry standard pricing services, data providers, security master files from large financial institutions and other third-party sources and uses those multiple prices as inputs into a distribution-curve-based algorithm to determine the daily market value. The pricing services use multiple inputs to determine market prices, including reportable trades, benchmark yield curves, credit spreads and broker/dealer quotes as well as other industry and economic events. For certain securities with short maturities, such as discount commercial paper and certificates of deposit, the security is accreted from purchase price to face value at maturity. If a subsequent transaction on the same security is observed in the marketplace, the price on the subsequent transaction is used as the current daily market price and the security will be accreted to face value based on the revised price. The Company validates the consensus prices by taking random samples from each asset type and corroborating those prices using reported trade activity, benchmark yield curves, binding broker/dealer quotes or other relevant price information. There have not been any changes to the Company’s fair value methodology during the third quarter of fiscal 2021, and the Company did not adjust or override any fair value measurements as of January 2, 2021. Fair Value Hierarchy The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. The guidance for fair value measurements requires that assets and liabilities carried at fair value be classified and disclosed in one of the following categories: Level 1 — Quoted (unadjusted) prices in active markets for identical assets or liabilities. Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3 — Unobservable inputs to the valuation methodology that are supported by little or no market activity and that are significant to the measurement of the fair value of the assets or liabilities. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation. Assets and Liabilities Measured at Fair Value on a Recurring Basis In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The following tables present information about the Company’s assets and liabilities measured at fair value on a recurring basis as of January 2, 2021 and March 28, 2020: January 2, 2021 (In thousands) Total Fair Assets Cash equivalents: Money market funds $ 334,209 $ — $ — $ 334,209 Financial institution securities — 174,988 — 174,988 Non-financial institution securities — 207,764 — 207,764 U.S. government and agency securities 36,999 83,995 — 120,994 Foreign government and agency securities — 121,470 — 121,470 Short-term investments: Financial institution securities — 299,991 — 299,991 Non-financial institution securities — 430,783 — 430,783 U.S. government and agency securities 643,877 341,331 — 985,208 Foreign government and agency securities — 376,855 — 376,855 Mortgage-backed securities — 89,617 — 89,617 Asset-backed securities — 856 — 856 Commercial mortgage-backed securities — 15,549 — 15,549 Derivative financial instruments, net — 6,756 — 6,756 Total assets measured at fair value $ 1,015,085 $ 2,149,955 $ — $ 3,165,040 March 28, 2020 (In thousands) Total Fair Assets Cash equivalents: Money market funds $ 656,038 $ — $ — $ 656,038 Financial institution securities — 175,000 — 175,000 Non-financial institution securities — 361,692 — 361,692 U.S. government and agency securities 150,999 62,274 — 213,273 Foreign government and agency securities — 244,300 — 244,300 Short-term investments: Financial institution securities — 150,000 — 150,000 Non-financial institution securities — 115,043 — 115,043 U.S. government and agency securities 1,000 2,000 — 3,000 Foreign government and agency securities — 9,973 — 9,973 Mortgage-backed securities — 158,804 — 158,804 Asset-backed securities — 2,549 — 2,549 Commercial mortgage-backed securities — 50,144 — 50,144 Total assets measured at fair value $ 808,037 $ 1,331,779 $ — $ 2,139,816 Liabilities Derivative financial instruments, net $ — $ 12,381 $ — $ 12,381 Total liabilities measured at fair value $ — $ 12,381 $ — $ 12,381 Net assets measured at fair value $ 808,037 $ 1,319,398 $ — $ 2,127,435 For certain of the Company’s financial instruments, including cash held in banks, accounts receivable and accounts payable, the carrying amounts approximate fair value due to their short maturities, and are therefore excluded from the fair value tables above. Financial Instruments Not Recorded at Fair Value on a Recurring Basis The Company's $500.0 million principal amount of 3.000% notes due March 15, 2021 (2021 Notes), $750.0 million principal amount of 2.950% senior notes due June 1, 2024 (2024 Notes) and $750.0 million principal amount of 2.375% senior notes due June 1, 2030 (2030 Notes) are measured at fair value on a quarterly basis for disclosure purposes. The fair values of the 2021 Notes, 2024 Notes and 2030 Notes as of January 2, 2021 were approximately $502.7 million, $807.8 million and $785.2 million, respectively, based on the last trading price for the period (classified as Level 2 in fair value hierarchy due to relatively low trading volume). Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis As of January 2, 2021, the Company had non-marketable securities in private companies of $107.4 million, which were classified as Level 3 assets. The Company’s investments in non-marketable equity securities of private companies are recorded at fair value if the Company recognizes an observable price adjustment or an impairment. Such impairment losses or observable price adjustments were not material during all periods presented. The Company’s investments in non-financial assets such as property, plant and equipment, goodwill and acquisition-related intangibles, are recorded at cost (net of accumulated depreciation or amortization, where applicable). These non-financial assets are reduced to fair value when impaired.

The marketable debt securities (U.S. and foreign government and agency securities, asset-backed securities, mortgage-backed securities and commercial mortgage-backed securities) are highly rated by the credit rating agencies, there have been no defaults on any of these securities and the Company has received interest payments as they become due. Therefore, the Company believes that it will be able to collect both principal and interest amount due to the Company. Additionally, in the past several years a portion of the Company's investment in the mortgage-backed securities was redeemed or prepaid by the debtors at par. Furthermore, the aggregate of individual unrealized losses that had been outstanding for twelve months or more was not significant as of January 2, 2021 and March 28, 2020. The Company neither intends to sell these investments nor concludes that it is more-likely-than-not that it will have to sell them until recovery of their carrying values. The amortized cost and estimated fair value of marketable debt securities, by contractual maturity, are shown in the table below. Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations without call or prepayment penalties. January 2, 2021 (In thousands) Amortized Estimated Due in one year or less $ 2,719,288 $ 2,719,301 Due after one year through five years 3,398 3,460 Due after five years through ten years 13,443 14,079 Due after ten years 86,426 87,235 $ 2,822,555 $ 2,824,075 As of January 2, 2021, $104.8 million of marketable debt securities with contractual maturities of greater than one year were classified as short-term investments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company’s primary objective for holding derivative financial instruments is to manage foreign currency exchange rate risk and interest rate risk. As a result of the use of derivative financial instruments, the Company is exposed to the risk that counterparties to derivative contracts may fail to meet their contractual obligations. The Company manages counterparty credit risk in derivative contracts by reviewing counterparty creditworthiness on a regular basis, establishing collateral requirement and limiting exposure to any single counterparty. The right of set-off that exists with certain transactions enables the Company to net amounts due to and from the counterparty, reducing the maximum loss from credit risk in the event of counterparty default. In March and May 2020, the Company entered into interest rate swap contracts with an independent financial institution in an effort to reduce the risk of changes in the underlying benchmark interest rate. During the first quarter of fiscal 2021, the Company unwound the interest rate swap contracts and recognized an immaterial loss. The loss is being amortized as an additional increase to interest expense over the remaining life of the 2030 Notes. There was no ineffectiveness during all periods presented.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation Plans	Stock-Based Compensation Plans The Company’s equity incentive plans are broad-based, long-term retention programs that cover employees, consultants and non-employee directors of the Company. These plans are intended to attract and retain talented employees, consultants and non-employee directors and to provide such persons with a proprietary interest in the Company. Stock-Based Compensation The following table summarizes stock-based compensation expense related to stock awards granted under the Company’s equity incentive plans and rights to acquire stock granted under the Company’s Employee Stock Purchase Plan (ESPP): Three Months Ended Nine Months Ended (In thousands) January 2, 2021 December 28, 2019 January 2, 2021 December 28, 2019 Stock-based compensation included in: Cost of revenues $ 3,465 $ 2,961 $ 9,149 $ 8,386 Research and development 40,228 31,543 106,707 86,119 Selling, general and administrative 22,638 15,653 59,297 48,227 $ 66,331 $ 50,157 $ 175,153 $ 142,732 In order to retain its current workforce and maintain continuous business operations during the pending period of the Merger, the Company implemented an employee retention bonus program in December 2020 for certain employees consisting of both cash bonuses and RSUs. The cash bonuses are payable in separate installments through the later of December 2021 or the closing of the Merger, and the RSUs will vest in equal annual installments over three years, with payment and vesting contingent upon a participant employee's continuing employment with the Company. The retention bonus program resulted in the issuance of 721 thousand RSUs. The stock-based compensation expense with respect to the retention bonus program was immaterial for the third quarter of fiscal 2021. Employee Stock Option Plans The types of awards allowed under the 2007 Equity Incentive Plan (2007 Equity Plan) include incentive stock options, non-qualified stock options, restricted stock units (RSUs), restricted stock and stock appreciation rights. As of January 2, 2021, 11.9 million shares remained available for grant under the 2007 Equity Plan. RSU Awards A summary of the Company’s RSU activity and related information is as follows: RSUs Outstanding (Shares in thousands) Number of Shares Weighted-Average Grant-Date Fair Value Per Share March 30, 2019 7,331 $ 59.54 Granted 2,756 $ 109.53 Vested (2,820) $ 55.24 Cancelled (487) $ 75.09 March 28, 2020 6,780 $ 80.53 Granted 3,785 $ 105.48 Vested (2,387) $ 70.61 Cancelled (594) $ 83.77 January 2, 2021 7,584 $ 95.46 The estimated fair values of RSUs were calculated based on the market price of Xilinx common stock on the date of grant, reduced by the present value of dividends expected to be paid on Xilinx common stock prior to vesting. For the RSUs granted during the fiscal quarter ended January 2, 2021, the Company does not expect to declare a dividend due to the required dividend suspension in connection with the Merger. The per share weighted-average fair value of RSUs granted during the third quarter of fiscal 2021 was $143.18 ($89.57 for the third quarter of fiscal 2020), which were calculated based on estimates at the date of grant using the following weighted-average assumptions: Three Months Ended Nine Months Ended January 2, 2021 December 28, 2019 January 2, 2021 December 28, 2019 Risk-free interest rate 0.2 % 1.6 % 0.2 % 1.8 % Dividend yield — % 1.6 % 1.2 % 1.3 % For the majority of RSUs granted, the number of shares of common stock issued on the date the RSU awards vest is net of the minimum statutory withholding requirements that the Company pays in cash to the appropriate taxing authorities on behalf of the Company's employees. During the first nine months of fiscal 2021 and 2020, the Company withheld $58.0 million and $75.4 million worth of RSU awards, respectively, to satisfy the employees’ tax obligations. During the third quarter and the first nine months of fiscal 2021, the Company realized excess tax benefits of $2.3 million and $15.0 million, respectively, primarily from RSU vesting. During the third quarter and the first nine months of fiscal 2020, the excess tax benefits were $1.3 million and $35.6 million, respectively, primarily from RSU vesting. These tax benefits were recorded in the condensed consolidated statements of income as a component of the provision for income taxes. Employee Stock Purchase Plan Under the Company’s ESPP, shares are only issued during the second and fourth quarters of each fiscal year. Employees purchased 283 thousand shares for $19.8 million during the second quarter of fiscal 2021 and 241 thousand shares for $19.7 million during the second quarter of fiscal 2020. The per-share weighted-average fair value of stock purchase rights granted under the ESPP during the second quarter of fiscal 2021 and 2020 was $31.40 and $33.79, respectively. The fair values of stock purchase plan rights granted in the second quarter of fiscal 2021 and 2020 were estimated using the Black-Scholes option pricing model at the date of grant using the following assumptions: 2021 2020 Expected life of options (years) 1.25 1.25 Expected stock price volatility 0.38 0.37 Risk-free interest rate 0.1 % 1.9 % Dividend yield 1.4 % 1.3 %

The diluted shares were calculated by applying the treasury stock method to the impact of the equity incentive plans. Certain shares of outstanding stock options and RSUs were excluded from diluted net income per common share calculation by applying the treasury stock method, as their inclusion would have been anti-dilutive. These excluded options and RSUs were immaterial for the third quarter and the first nine months of fiscal 2021 and 2020, respectively, but could be dilutive in the future if the Company’s average share price increases and is greater than the combined exercise prices and the unamortized fair values of these options and RSUs.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded tax provisions of $5.2 million and $75.5 million for the third quarter and the first nine months of fiscal 2021, respectively, representing effective tax rates of 2.9% and 14.1%, respectively. The Company recorded tax provisions of $3.8 million and $13.8 million for the third quarter and the first nine months of fiscal 2020, respectively, representing effective tax rates of 2.3% and 2.1%, respectively. The difference between the U.S. federal statutory tax rate of 21% and the Company's effective tax rate in all periods presented was primarily due to the beneficial impact of income earned in lower tax rate jurisdictions and excess tax benefits with respect to stock-based compensation, which was partially offset by the U.S. tax on global intangible low-taxed income (GILTI). In addition, the first nine months of fiscal 2021 included the recognition of prior period tax and interest related to impacts of including stock-based compensation in the intercompany research and development (R&D) cost sharing arrangement. On June 22, 2020, the United States Supreme Court denied certiorari in the case of Altera Corp. v. Commissioner (Altera). The company is not a party to the proceedings but is subject to the findings of the case. The Altera tax case concerns related party R&D cost sharing arrangements and whether stock-based compensation should be included in the pool of costs to be shared. With the Supreme Court’s decision not to hear the Altera case, the decision of the 9th Circuit (which applies to taxpayers such as Xilinx) that stock-based compensation is to be included in the pool of costs to be shared remains in place. During the fiscal quarter ended June 27, 2020, the Company recorded a one-time charge of $56.8 million for prior year taxes and interest representing the cumulative adverse impact for fiscal 2017 through fiscal 2020. Despite the decision in the Altera case, the Company has concluded the related law remains unsettled and will continue to monitor developments and the potential effect on its consolidated financial statements and tax filings. The Company’s total gross unrecognized tax benefits as of January 2, 2021, determined in accordance with authoritative guidance for measuring uncertain tax positions, decreased by $2.6 million in the third quarter of fiscal 2021 to $152.3 million. The total amount of unrecognized tax benefits that, if realized in a future period, would favorably affect the effective tax rate was $115.4 million as of January 2, 2021. It is reasonably possible that changes to the Company's unrecognized tax benefits could be significant in the next twelve months due to tax audit settlements and lapses of statutes of limitation. As a result of uncertainties regarding tax audit settlements and their possible outcomes, an estimate of the range of increase or decrease that could occur in the next twelve months cannot be made. The Company’s policy is to include interest and penalties related to income tax liabilities within the provision for income taxes on the condensed consolidated statements of income. The balance of accrued interest and penalties recorded in the condensed consolidated balance sheets was $5.0 million as of January 2, 2021 and not material for the prior period presented. The amounts of interest and penalties included in the Company's provision for income taxes were not material for all periods presented. The statutes of limitations have closed for U.S. federal income tax purposes for years through fiscal 2016, for significant U.S. state income tax purposes for years through fiscal 2014, and for Ireland income tax purposes for years through fiscal 2015.

Product Warranties Disclosures [Abstract]
Product Warranty Disclosure [Text Block]	Product Warranty and Indemnification The Company generally sells products with a limited warranty for product quality. The Company provides an accrual for known product issues if a loss is probable and can be reasonably estimated. As of the end of the third quarter of fiscal 2021 and the end of fiscal 2020, the accrual balances of the product warranty liability were immaterial. The Company offers, subject to certain terms and conditions, to indemnify customers and distributors for costs and damages awarded against these parties in the event the Company’s hardware products are found to infringe third-party intellectual property rights, including patents, copyrights or trademarks, and to compensate certain customers for limited specified costs they actually incur in the event the Company's hardware products experience epidemic failure. To a lesser extent, the Company may from time-to-time offer limited indemnification with respect to its software products. The terms and conditions of these indemnity obligations are limited by contract, which obligations are typically perpetual from the effective date of the agreement. The Company has historically received only a limited number of requests for indemnification under these provisions and has not made any significant payments pursuant to these provisions. The Company cannot estimate the maximum amount of potential future payments, if any, that the Company may be required to make as a result of these obligations due to the limited history of indemnification claims and the unique facts and circumstances that are likely to be involved in each particular claim and indemnification provision. However, there can be no assurances that the Company will not incur any financial liabilities in the future as a result of these obligations.

The Company is unable to estimate its range of possible loss, if any, in this matter at this time. The Company intends to continue to protect and defend its IP vigorously. Shareholder Litigation On December 7, 2020, a purported stockholder of the Company filed a complaint in the United States District Court for the Northern District of California against the Company and the members of its board of directors (Stein v. Xilinx, Inc., et al., Case No. 5:20-cv-08637). The complaint alleges that the registration statement issued in connection with the Merger omitted material information in violation of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, Rule 14a-9 thereunder and SEC Regulation G, rendering the registration statement false and misleading. Specifically, the complaint alleges that the registration statement failed to disclose material information regarding AMD's and the Company’s financial projections and Credit Suisse's discounted cash flow analyses of the Company and AMD. The complaint seeks an order: enjoining the Merger unless and until additional disclosures are issued; rescinding the Merger, to the extent it closes; awarding damages; awarding costs, including attorneys’ fees, expert fees and expenses; and awarding such other relief as the court deems proper. On December 11, 2020, a purported stockholder of the Company filed a putative class-action complaint in the New York Supreme Court against the Company, the members of its board of directors, AMD and Merger Sub (Nunez v. Xilinx, Inc., et al., Case No. 656971/2020). The complaint alleges that the Company's board of directors breached their fiduciary duties by entering into the Merger, agreeing to purportedly preclusive deal protection terms and engaging in an allegedly flawed process that did not involve an adequate market check or approval by a committee of disinterested and independent directors. The complaint also alleges that the Company's board of directors "caused to be filed" the registration statement issued in connection with the Merger that purportedly omitted material information with respect to the Merger. The registration statement allegedly omits information regarding the sale process, AMD's and the Company's financial projections, certain details regarding the financial analyses performed by each of Morgan Stanley, Bank of America, Credit Suisse and DBO and certain details regarding compensation for Morgan Stanley. Finally, the complaint alleges that the Company and AMD aided and abetted the Company's board of directors in their breach of fiduciary duties. The complaint seeks certification of a class action, injunctive relief enjoining the Merger, damages and costs, among other remedies. On December 11, 2020, a purported stockholder of the Company filed a complaint in the United States District Court for the District of Colorado against the Company and the members of its board of directors (Hale v. Xilinx, Inc., et al., Case No. 1:20-cv-03629). The complaint raises federal securities disclosure claims and alleges, among other things, that the registration statement issued in connection with the Merger omitted material information with respect to the Merger, including information regarding AMD's and the Company's financial projections, certain details regarding the financial analyses performed by Morgan Stanley and Bank of America, and certain details regarding compensation for Morgan Stanley. The complaint seeks injunctive relief enjoining the Merger, damages and costs, among other remedies. On December 15, 2020, a purported stockholder of the Company filed a complaint in the United States District Court for the Southern District of New York against the Company, the members of its board of directors, AMD and Merger Sub (Shumacher v. Xilinx, Inc., et al., Case No. 1:20-cv-10595). The complaint raises federal securities disclosure claims and alleges, among other things, that the registration statement issued in connection with the Merger omitted material information with respect to the Merger, including information regarding AMD's and the Company's financial projections, certain details regarding the financial analyses performed by Morgan Stanley and Bank of America, and certain details regarding compensation for Morgan Stanley. The complaint seeks injunctive relief enjoining the merger, damages and costs, among other remedies. On December 18, 2020, a purported stockholder of the Company filed a complaint in the United States District Court for the Southern District of New York against the Company and the members of its board of directors (Achterberg v. Xilinx, Inc., et al., Case No. 1:20-cv-10715). The complaint raises federal securities disclosure claims and alleges, among other things, that the registration statement issued in connection with the Merger omitted material information with respect to the Merger, including information regarding AMD's and the Company's financial projections and certain details regarding the financial analyses performed by Morgan Stanley and Bank of America. The complaint seeks injunctive relief enjoining the Merger, an amended registration statement, damages and costs, among other remedies. On December 30, 2020, a purported stockholder of the Company filed a complaint in the United States District Court for the Northern District of California against Xilinx and the members of its board of directors (Sandhu v. Xilinx, Inc., et al., Case No. 5:20-cv-09440). The complaint raises federal securities disclosure claims and alleges, among other things, that the registration statement issued in connection with the Merger omitted material information with respect to the Merger, including information regarding AMD's and the Company's financial projections, certain details regarding the financial analyses performed by Morgan Stanley and Bank of America, and certain details regarding compensation for Morgan Stanley. The complaint seeks injunctive relief enjoining the Merger, damages and costs, among other remedies. The Company believes that the allegations in the shareholder litigation matters are without merit. Other Matters On June 11, 2015, John P. Neblett, as Chapter 7 Trustee of Valley Forge Composite Technologies, Inc., filed a complaint against Xilinx and others in the U.S. Bankruptcy Court for the Middle District of Pennsylvania (Bankruptcy No. 1:13-bk-05253-JJT). The complaint alleges causes of actions against Xilinx for negligence and civil conspiracy relating to alleged violations of U.S. export laws. It seeks at least $50.0 million in damages, together with punitive damages, from the defendants. On September 21, 2015, the action was withdrawn from the U.S. Bankruptcy Court for the Middle District of Pennsylvania and transferred to the U.S. District Court for the Eastern District of Kentucky. On November 2, 2015, Xilinx, along with other defendants, filed a motion to dismiss the complaint. On November 3, 2015, Xilinx filed a motion for sanctions pursuant to Federal Rule of Civil Procedure 11. On June 27, 2016, the Court denied both motions. On September 11, 2017, Xilinx, along with other defendants, filed motions for summary judgment seeking to dispose of all claims against them. On July 3, 2018, the Court granted both of Xilinx’s motions for summary judgment, disposing of all claims asserted against Xilinx. On August 1, 2018, the Trustee filed a notice of appeal. On August 9, 2018, the Court of Appeals for the Sixth Circuit issued an order to show cause requesting that the appellant address a possible jurisdictional defect. On August 29, 2018, the appellant responded to the order to show cause. On September 10, 2018, appellees, including Xilinx, filed a joint reply. On January 7, 2019, the Court of Appeals issued an order dismissing the appeal for lack of jurisdiction. On February 19, 2019, the District Court issued an order permitting any party seeking to certify the case for appeal to file a motion. On March 11, 2019, defendant Avnet filed a motion to certify the case for appeal. On May 14, 2019 the Court denied Avnet’s motion. On June 4, 2019, Avnet and the counterclaim and crossclaim defendants stipulated to dismissal of Avnet’s remaining counterclaims and crossclaims. The Court entered final judgment on June 25, 2019. On July 22, 2019, the Trustee filed his notice of appeal and filed his opening appellate brief on September 17, 2019. On October 30, 2019, Xilinx filed its appellee brief. On November 20, 2019, the Trustee filed his reply brief. On April 7, 2020, the Sixth Circuit affirmed the District Court’s judgment which granted both of Xilinx’s motions for summary judgment, disposing of all claims asserted against Xilinx. On April 14, 2020, the Trustee filed a motion to extend the time for filing a petition for rehearing, and the Sixth Circuit granted the motion extending the due date until May 14, 2020. On May 14, 2020, the Trustee filed a petition for a rehearing. On August 11, 2020, the petition for a rehearing was denied. From time to time, the Company is involved in various disputes and litigation matters that arise in the ordinary course of its business. These include disputes and lawsuits related to intellectual property, mergers and acquisitions, licensing, contract law, tax, regulatory, distribution arrangements, employee relations and other matters. Periodically, the Company reviews the status of each matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and a range of possible losses can be estimated, the Company accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based only on the best information available at the time. As additional information becomes available, the Company continues to reassess the potential liability related to pending claims and litigation and may revise estimates.
