CADENCE CAPS STRONG 2004 WITH SOLID Q4 EXECUTION

     SAN JOSE, Calif.—Feb. 3, 2005—Cadence Design Systems, Inc. (NYSE: CDN) (Nasdaq: CDN) today reported strong results for the fourth quarter and the full year 2004. Fourth quarter revenues were $343 million, compared to $311 million for the same period last year. Full year revenues totaled $1.20 billion, an increase of 7 percent over 2003 total revenues of $1.12 billion. On a GAAP basis, Cadence recognized net income of $60 million, or $0.20 per share, in the fourth quarter of 2004, compared to net income of $15 million, or $0.05 per share, in the same period last year. On a full year basis, Cadence net income for 2004 was $74 million, or $0.25 per share, compared to a net loss of $18 million and a diluted net loss per share of ($0.07) for the year 2003.

     In addition to using GAAP results in evaluating Cadence’s business, management also believes it is useful to measure results using a non-GAAP measure of net income (loss), which excludes, as applicable, amortization of intangible assets and deferred stock compensation, in-process research and development charges, integration and other acquisition-related expenses, restructuring charges and equity in losses (income) from investments. Non-GAAP net income (loss) is adjusted by the amount of additional taxes or tax benefit that the company would accrue if it used non-GAAP results instead of GAAP results to calculate the company’s tax liability. See “GAAP to non-GAAP Reconciliation” below for further information on our non-GAAP measure. Using this non-GAAP measure, net income in the fourth quarter 2004 was $80 million, or $0.26 per share, on a fully diluted basis as compared to $65 million, or $0.22 per share, on a fully diluted basis, in the same period last year. On a full year basis, non-GAAP net income for 2004 was $201 million, or $0.66 per share, compared to $140 million and $0.50 per share in 2003.

     “Cadence continued its consistent execution, in a challenging marketplace,” said Mike Fister, Cadence president and CEO. “Strong demand for wireless, consumer electronics and high-

Page 1

performance computing plays to our specific strengths in analog mixed-signal and low-power digital design.”

Business Highlights of 2004

     Cadence® SoC Encounter™ helped customers like ATI, Fujitsu and Toshiba, among others, design some of the largest, most aggressive digital chips currently in production. Toshiba taped out a 90-nanometer, 24-million-gate chip and adopted Encounter as its standard digital design flow.

     During 2004, 58 new customers adopted Encounter RTL Compiler, Cadence’s digital global synthesis product. Well over 400 customers around the world now verify their leading-edge designs with Encounter Conformal®, Cadence’s digital formal verification product.

     Customers are leveraging Cadence’s end-to-end platform strengths in analog, digital and RF to meet their needs in the growing wireless market. Customer productivity improved five to 10 times in analog circuit optimization as a result of Cadence’s integration of the NeoLinear technology into the Virtuoso® custom design platform.

     To meet the growing demand for concurrent hardware/software development, in Q4 Cadence introduced Palladium II, its most advanced emulator. Palladium II achieves an industry first by reaching 256-million-gate capacity at the same time as providing increased throughput.

     “This quarter’s performance culminates a strong year for Cadence,” Fister said. “Due to time-to-market pressures and the increased complexity of semiconductors, customers are increasingly turning to Cadence for an integrated, end-to-end solution across all design domains.”

     Added Bill Porter, senior vice president and Chief Financial Officer: “I’m proud of our strong balance sheet and especially pleased with our cash generation, highlighted by $371 million in operating cash flow for 2004.”

The following statements are based on current expectations. These statements are forward looking, and actual results may differ materially. These statements do not include the impact of any mergers, acquisitions or other business combinations that may be completed after February 3, 2005, other than Verisity, Ltd.

Business Outlook

     For the first quarter of 2005, the company expects total revenue in the range of $280 million to $290 million. First quarter GAAP earnings per fully diluted share are expected to be in the range of $0.01 to $0.03. Diluted earnings per share using our non-GAAP measure defined below are expected to be in the range of $0.13 to $0.15.

Page 2

     For the full year 2005, the company expects total revenue in the range of $1.24 billion to $1.30 billion. On a GAAP basis, we expect net income per fully diluted share for fiscal 2005 in the range of $0.23 to $0.31. Using our non-GAAP measure defined below, we expect fully diluted earnings per share for fiscal 2005 to be in the range of $0.73 to $0.81.

     A schedule showing a reconciliation of the business outlook from GAAP net income (loss) and diluted net income (loss) per share to our non-GAAP net income (loss) and diluted net income (loss) per share is included with this release.

The statements contained above regarding the company’s fourth quarter 2004 results and results for the full year 2004, those contained in the Business Outlook section above and the statements by Mike Fister and Bill Porter include forward looking statements based on current expectations or beliefs, as well as a number of preliminary assumptions about future events that are subject to factors and uncertainties that could cause actual results to differ materially from those described in the forward looking statements. Readers are cautioned not to put undue reliance on these forward looking statements, which are not a guarantee of future performance and are subject to a number of uncertainties and other factors, many of which are outside Cadence’s control, including, among others: Cadence’s ability to compete successfully in the design automation product and the commercial electronic design and methodology services industries; the mix of products and services sold and the timing of significant orders for its products; economic uncertainty; fluctuations in rates of exchange between the U.S. dollar and the currencies of other countries in which Cadence does business; and the acquisition of other companies or the failure to

GAAP to non-GAAP Reconciliation

     Cadence management evaluates and makes operating decisions using various operating measures. These measures are generally based on the revenues of its product, maintenance and services business operations and certain costs of those operations, such as cost of revenues, research and development, sales and marketing and general and administrative expenses. One such measure is non-GAAP net income (loss), which is a non-GAAP financial measure under Section 101 of Regulation G under the Securities Exchange Act of 1934, as amended. This measure consists of GAAP net income (loss) excluding, as applicable, amortization of intangible assets and deferred stock compensation, in-process research and development charges, integration and other acquisition-related expenses, restructuring charges (severance and benefits, excess facilities and asset-related restructuring charges) and equity in losses (income) from investments. Intangible assets consist primarily of purchased technology, backlog, patents, trademarks, distribution rights, customer contracts and related relationships and non-compete agreements. Non-GAAP net income (loss) is adjusted by the amount of additional taxes or tax benefit that the company would accrue if it used non-GAAP results instead of GAAP results to calculate the company’s tax liability.

     Management believes it is useful in measuring Cadence’s operations to exclude amortization of intangibles, deferred stock compensation, in-process research and development and acquisition-related expenses because these costs are primarily fixed at the time of an acquisition and generally cannot be changed by management in the short term. Management believes that it also is useful to exclude restructuring costs. Cadence has dramatically reduced the size of its design services business and portions of its product and maintenance businesses over the past three years. As a result, in 2001, 2002 and 2003, Cadence’s GAAP statements of operations have included significant charges relating to such restructurings. Cadence believes that in measuring its operations it is useful to exclude such restructuring costs because the company’s level of restructuring activities is expected to significantly decrease in the foreseeable future. Management also believes it is useful to exclude the equity in losses (income) from investments and investment write-downs, as these costs are not part of the company’s direct cost of operations. Rather, these are non-operating costs that are included in other income (expense) and are part of the company’s investment activities.

     Management believes that non-GAAP net income (loss) provides useful supplemental information to management and investors regarding the performance of the company’s business operations and facilitates comparisons to our historical operating results. Management also uses this information internally for forecasting and budgeting. Non-GAAP financial measures should not be considered as a substitute for measures of financial performance prepared in accordance with GAAP. Investors and potential investors are encouraged to review the reconciliation of non-GAAP financial measures contained within this press release with their most directly comparable GAAP financial results.

     The following table reconciles the specific items excluded from GAAP in the calculation of non-GAAP net income for the periods shown below:

(A)   Shares used in the calculation of GAAP earnings per share are expected to be the same as shares used in the calculation of non-GAAP earnings per share except when the company reports a GAAP loss and non-GAAP income, or GAAP income and a non-GAAP loss.

Investors are encouraged to look at GAAP results as the best measure of financial performance. For example, amortization of intangibles or amortization of deferred stock compensation or in-process technology are important to consider because they may represent initial expenditures that under GAAP are reported across future fiscal periods. Likewise, deferred stock compensation expense is an obligation of the company that should be considered. Restructuring charges can be triggered by acquisitions or product adjustments as well as overall company performance within a given business environment. All of these metrics are important to financial performance generally.

Though Cadence management finds its non-GAAP measure useful in evaluating the performance of Cadence’s business, its reliance on this measure is limited because items excluded from such measures often have a material effect on Cadence’s earnings and earnings per share calculated in accordance with GAAP. Therefore, Cadence management typically uses its non-GAAP earnings and earnings per share measures in conjunction with GAAP earnings and earnings per share measures, to address these limitations.

Cadence believes that presenting its non-GAAP measure of earnings and earnings per share provides investors with an additional tool for evaluating the performance of the company’s business, which management uses in its own evaluation of performance, and an additional base line for assessing the future earnings potential of the company. While the GAAP results are more complete, the company prefers to allow investors to have this supplemental measure since, with reconciliation to GAAP, it may provide additional insight into our financial results.

Cadence expects that its corporate representatives will meet privately during the quarter with investors, the media, investment analysts and others. At these meetings, Cadence may reiterate the Business Outlook published in this press release. At the same time, Cadence will keep this press release, including the outlook, publicly available on its Web site.

Prior to the start of the Quiet Period (described below), the public may continue to rely on the Business Outlook contained herein as still being Cadence’s current expectations on matters covered unless Cadence publishes a notice stating otherwise.

Beginning March 18, 2005, Cadence will observe a “Quiet Period” during which the Business Outlook as provided in this press release and the company’s most recent annual report on Form 10-K no longer constitute the company’s current expectations. During the Quiet Period, the Business Outlook in these documents should be considered to be historical, speaking as of prior to the Quiet Period only and not subject to update by the company. During the Quiet Period, Cadence representatives will not comment on Cadence’s business outlook or its financial results or expectations. The Quiet Period will extend until the day when Cadence’s First Quarter 2005 Earnings Release is published, currently scheduled for April 27, 2005.
