Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by Cadence Design Systems, Inc., or Cadence, without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission, or the SEC. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, Cadence believes that the disclosures contained in this Quarterly Report on Form 10-Q comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, for a Quarterly Report on Form 10-Q and are adequate to make the information presented not misleading. These condensed consolidated financial statements are meant to be, and should be, read in conjunction with the consolidated financial statements and the Notes thereto included in Cadence’s Annual Report on Form 10-K for the fiscal year ended January 3, 2015 . Certain prior period balances have been reclassified to conform to current period presentation. The unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q reflect all adjustments (which include only normal, recurring adjustments and those items discussed in these Notes) that are, in the opinion of management, necessary to state fairly the results of operations, cash flows and financial position for the periods and dates presented. The results for such periods are not necessarily indicative of the results to be expected for the full fiscal year. Management has evaluated subsequent events through the issuance date of the unaudited condensed consolidated financial statements. Preparation of the condensed consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Debt Disclosure [Abstract]
DEBT	DEBT Cadence’s outstanding debt as of July 4, 2015 and January 3, 2015 was as follows: July 4, 2015 January 3, 2015 (In thousands) Principal Unamortized Discount Carrying Value Principal Unamortized Discount Carrying Value 2015 Notes $ — $ — $ — $ 349,999 $ (7,500 ) $ 342,499 2024 Notes 350,000 (1,267 ) 348,733 350,000 (1,324 ) 348,676 Revolving credit facility — — — — — — Total outstanding debt $ 350,000 $ (1,267 ) $ 348,733 $ 699,999 $ (8,824 ) $ 691,175 2015 Notes In June 2010, Cadence issued $350.0 million principal amount of 2.625% Cash Convertible Senior Notes due June 1, 2015, or the 2015 Notes. During the six months ended July 4, 2015 , Cadence settled the outstanding principal amount of $350.0 million and paid note holders accrued interest of $3.8 million . The 2015 Notes contained a conversion feature, or the 2015 Notes Embedded Conversion Derivative, that entitled the holders of the notes to receive additional cash payments if the notes were converted prior to maturity. During the six months ended July 4, 2015 , Cadence paid $530.6 million to holders of the 2015 notes that converted prior to maturity. Cadence received proceeds of $530.6 million from the 2015 Notes Hedges, which fully offset the additional cash payments associated with the 2015 Notes Embedded Conversion Derivative. 2015 Notes Hedges Cadence entered into hedge transactions, or the 2015 Notes Hedges, in connection with the issuance of the 2015 Notes. The purpose of the 2015 Notes Hedges was to limit Cadence’s exposure to the additional cash payments above the principal amount of the 2015 Notes that was due to the holders who elected to convert their notes prior to maturity. As a result of the 2015 Notes Hedges, Cadence’s maximum cash exposure upon conversion or maturity of the 2015 Notes was the remaining principal balance of the notes and accrued interest. The 2015 Notes Hedges expired on June 1, 2015, and were settled in cash. 2015 Warrants At the time of issuance of the 2015 Notes, Cadence entered into separate warrant transactions, or the 2015 Warrants, for the purchase of up to approximately 46.4 million shares of Cadence’s common stock at a strike price of $10.78 per share, for total proceeds of $37.5 million , which was recorded as an increase in stockholders’ equity. As a result of the 2015 Warrants, Cadence experiences dilution to its diluted earnings per share when its average closing stock price exceeds $10.78 for any fiscal quarter until the warrants expire. The 2015 Warrants expire daily over a 70-day period between September and December 2015 . Cadence will be required to issue shares of common stock to the purchasers of the 2015 Warrants that represent the value by which the specified daily volume weighted average price of Cadence’s common stock exceeds the strike price of $10.78 stipulated in the warrant agreements. 2015 Notes Interest Expense The effective interest rate and components of interest expense of the 2015 Notes for the three and six months ended July 4, 2015 and June 28, 2014 were as follows: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands, except percentages) Effective interest rate 8.1 % 8.1 % 8.1 % 8.1 % Contractual interest expense $ 1,178 $ 2,289 $ 2,987 $ 4,578 Amortization of debt discount $ 2,470 $ 4,275 $ 7,500 $ 8,507 2024 Notes In October 2014, Cadence issued $350.0 million aggregate principal amount of 4.375% Senior Notes due October 15, 2024, or the 2024 Notes. Cadence received net proceeds of $342.4 million from issuance of the 2024 Notes, net of a discount of $1.4 million and issuance costs of $6.2 million . Both the discount and issuance costs will be amortized to interest expense over the term of the 2024 Notes using the effective interest method. Interest is payable in cash semi-annually in April and October. The 2024 Notes are unsecured and rank equal in right of payment to all of Cadence’s existing and future senior indebtedness. Cadence may redeem the 2024 Notes, in whole or in part, at a redemption price equal to the greater of (a) 100% of the principal amount of the notes to be redeemed and (b) the sum of the present values of the remaining scheduled payments of principal and interest, plus any accrued and unpaid interest, as more particularly described in the indenture governing the 2024 Notes. The indenture governing the 2024 Notes includes customary representations, warranties and restrictive covenants, including, but not limited to, restrictions on our ability to grant liens on assets, enter into sale and lease-back transactions, or merge, consolidate or sell assets, and also includes customary events of default. Revolving Credit Facility Cadence maintains a senior unsecured revolving credit facility with a group of lenders led by Bank of America, N.A., as administrative agent. The credit facility provides for borrowings up to $250.0 million , with the right to request increased capacity up to an additional $150.0 million upon the receipt of lender commitments, for total maximum borrowings of $400.0 million . The credit facility, as amended, expires on September 19, 2019 and has no subsidiary guarantors. Any outstanding loans drawn under the credit facility are due at maturity on September 19, 2019 . Outstanding borrowings may be paid at any time prior to maturity. Interest accrues on borrowings under the credit facility at either LIBOR plus a margin between 1.25% and 2.0% per annum or at the base rate plus a margin between 0.25% and 1.0% per annum. The interest rate applied to borrowings is determined by Cadence’s consolidated leverage ratio as specified by the credit facility agreement. Interest is payable quarterly. A commitment fee ranging from 0.20% to 0.35% is assessed on the daily average undrawn portion of revolving commitments. The credit facility contains customary negative covenants that, among other things, restrict Cadence’s ability to incur additional indebtedness, grant liens, make certain investments (including acquisitions), dispose of certain assets and make certain payments, including share repurchases and dividends. In addition, the credit facility contains financial covenants that require Cadence to maintain a leverage ratio not to exceed 2.75 to 1, and a minimum interest coverage ratio of 3 to 1. As of July 4, 2015 and January 3, 2015 , Cadence had no outstanding balance under the revolving credit facility and was in compliance with all financial covenants.

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets; • Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the six months ended July 4, 2015 . On a quarterly basis, Cadence measures at fair value certain financial assets and liabilities. The fair value of financial assets and liabilities was determined using the following levels of inputs as of July 4, 2015 and January 3, 2015 : Fair Value Measurements as of July 4, 2015: Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 415,443 $ 415,443 $ — $ — Short-term investments: Corporate debt securities 36,258 — 36,258 — Bank certificates of deposit 13,107 — 13,107 — United States Treasury securities 34,040 34,040 — — United States government agency securities 7,159 7,159 — — Commercial paper 4,195 — 4,195 — Marketable equity securities 1,801 1,801 — — Trading securities held in Non-Qualified Deferred Compensation, or NQDC, trust 24,226 24,226 — — Total Assets $ 536,229 $ 482,669 $ 53,560 $ — Total Level 1 Level 2 Level 3 (In thousands) Liabilities Foreign currency exchange contracts 536 — 536 — Total Liabilities $ 536 $ — $ 536 $ — Fair Value Measurements as of January 3, 2015: Total Level 1 Level 2 Level 3 (In thousands) Assets Cash equivalents: Money market funds $ 728,496 $ 728,496 $ — $ — Short-term investments: Corporate debt securities 34,894 — 34,894 — Bank certificates of deposit 21,910 — 21,910 — United States Treasury securities 19,374 19,374 — — United States government agency securities 9,208 9,208 — — Commercial paper 3,186 — 3,186 — Marketable equity securities 1,873 1,873 — — Trading securities held in NQDC trust 27,034 27,034 — — 2015 Notes Hedges 523,930 — 523,930 — Total Assets $ 1,369,905 $ 785,985 $ 583,920 $ — Total Level 1 Level 2 Level 3 (In thousands) Liabilities 2015 Notes Embedded Conversion Derivative 523,930 — 523,930 — Foreign currency exchange contracts 3,163 — 3,163 — Total Liabilities $ 527,093 $ — $ 527,093 $ —

Earnings Per Share [Abstract]
NET INCOME PER SHARE	NET INCOME PER SHARE Basic net income per share is computed by dividing net income during the period by the weighted average number of shares of common stock outstanding during that period, less unvested restricted stock awards. Diluted net income per share is impacted by equity instruments considered to be potential common shares, if dilutive, computed using the treasury stock method of accounting. The calculations for basic and diluted net income per share for the three and six months ended July 4, 2015 and June 28, 2014 are as follows: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands, except per share amounts) Net income $ 58,160 $ 23,263 $ 94,419 $ 56,333 Weighted average common shares used to calculate basic net income per share 285,297 283,344 284,910 282,480 2015 Warrants 20,635 15,054 19,773 13,815 Stock-based awards 7,733 7,357 8,073 7,100 Weighted average common shares used to calculate diluted net income per share 313,665 305,755 312,756 303,395 Net income per share - basic $ 0.20 $ 0.08 $ 0.33 $ 0.20 Net income per share - diluted $ 0.19 $ 0.08 $ 0.30 $ 0.19 The following table presents shares of Cadence’s common stock outstanding for the three and six months ended July 4, 2015 and June 28, 2014 that were excluded from the computation of diluted net income per share because the effect of including these shares in the computation of diluted net income per share would have been anti-dilutive: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) Options to purchase shares of common stock 1,503 4,399 1,308 4,517 Non-vested shares of restricted stock 23 8 18 9 Total potential common shares excluded 1,526 4,407 1,326 4,526

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES Legal Proceedings From time to time, Cadence is involved in various disputes and litigation that arise in the ordinary course of business. These include disputes and lawsuits related to intellectual property, indemnification obligations, mergers and acquisitions, licensing, contracts, distribution arrangements and employee relations matters. At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates. Other Contingencies Cadence provides its customers with a warranty on sales of hardware products, generally for a 90 -day period. Cadence did not incur any significant costs related to warranty obligations during the three and six months ended July 4, 2015 and June 28, 2014 . Cadence’s product license and services agreements typically include a limited indemnification provision for claims from third parties relating to Cadence’s intellectual property. If the potential loss from any indemnification claim is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. The indemnification is generally limited to the amount paid by the customer. Cadence did not incur any significant losses from indemnification claims during the three and six months ended July 4, 2015 and June 28, 2014 .

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING Segment reporting is based on the “management approach,” following the method that management organizes the company’s reportable segments for which separate financial information is made available to, and evaluated regularly by, the chief operating decision maker in allocating resources and in assessing performance. Cadence’s chief operating decision maker is its President and Chief Executive Officer, or CEO, who reviews Cadence’s consolidated results as one operating segment. In making operating decisions, the CEO primarily considers consolidated financial information, accompanied by disaggregated information about revenues by geographic region. Outside the United States, Cadence markets and supports its products and services primarily through its subsidiaries. Revenue is attributed to geography based upon the country in which the product is used or services are delivered. Long-lived assets are attributed to geography based on the country where the assets are located. The following table presents a summary of revenue by geography for the three and six months ended July 4, 2015 and June 28, 2014 : Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) Americas: United States $ 192,176 $ 161,874 $ 379,383 $ 325,202 Other Americas 7,425 6,050 12,839 11,834 Total Americas 199,601 167,924 392,222 337,036 Asia 96,426 88,286 195,208 175,302 Europe, Middle East and Africa 82,014 82,074 160,584 159,606 Japan 37,842 40,504 79,235 85,394 Total $ 415,883 $ 378,788 $ 827,249 $ 757,338 The following table presents a summary of long-lived assets by geography as of July 4, 2015 and January 3, 2015 : As of July 4, January 3, (In thousands) Americas: United States $ 194,071 $ 200,760 Other Americas 448 578 Total Americas 194,519 201,338 Asia 22,846 22,145 Europe, Middle East and Africa 11,870 5,951 Japan 603 678 Total $ 229,838 $ 230,112

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Preparation of the condensed consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value of Financial Instruments	Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets; • Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the six months ended July 4, 2015 .
Contingencies	At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates.
