Cadence Design Systems

Founded in 1983 in San Jose, California, Cadence Design Systems began as an electronic design automation (EDA) company named Solomon Design Automation (SDA). SDA's cofounders included James Solomon, Richard Newton, and Alberto Sangiovanni-Vincentelli.{{Cite web|url=https://www.eetimes.com/author.asp?section_id=67&doc_id=1285941|title=Alberto Sangiovanni-Vincentelli receives EDAA Lifetime Achievement Award|last=Bailey|first=Brian|date=December 20, 2017|website=EE Times}} Cadence was formed by the merger of SDA and ECAD. A public company, ECAD had been co-founded by Ping Chao, Glen Antle, and Paul Huang in 1982.{{Not in source|date=March 2024}} Cadence Design Systems was officially formed through SDA and ECAD's 1988 merger, with Joseph Costello was appointed both CEO and president of the newly combined company. After the merger, Cadence began trading on the New York Stock Exchange and Costello oversaw further mergers and acquisitions.NYTimes [https://www.nytimes.com/1991/10/04/business/business-people-a-fun-chief-at-cadence-is-serious-merger-man.html A Fun Chief at Cadence Is Serious Merger Man] Retrieved October 4, 1991

In 1989, the company acquired Gateway Design Automation for $72 million. In 1990 it acquired Automated Systems Inc., and in doing so added "board design to its existing line of chip design software." In 1991, Cadence acquired its rival Valid Logic Systems for around $200 million, its biggest acquisition yet. The revenues of the combined company were $390 million, making Cadence "the largest provider of the software used by electronic engineers to design computer chips and circuit boards," according to the New York Times.

In 1996, Cadence acquired High Level Design Systems, at which point Cadence had 3,300 employees and $742 million in annual revenue. Following the resignation of Cadence's original CEO Joe Costello in 1997, Jack Harding was appointed CEO.WSJ [https://www.wsj.com/articles/SB877391809854588000 Cadence's Costello Steps Down As CEO to Join Software Firm] Retrieved October 21, 1997 Ray Bingham was named CEO in 1999.EETimes [https://www.eetimes.com/harding-replaced-as-cadence-president/ Harding replaced as Cadence president] Retrieved April 27, 1999 Cadence purchased Ambit Design Systems for $260 million, which made tools for system-on-a-chip technology, in 1998, and OrCAD Systems in 1999. After acquiring Quickturn Design in 1999, Cadence was described as a "white knight" for the act by the New York Times, as Quickturn had been subject to a hostile takeover by Cadence's rival Mentor Graphics.

Under urging by executives such as Jim Hogan and executive vice president Penny Herscher, between 2001 and 2003, Cadence purchased a number of implementation tools through acquisition, such as Silicon Perspective, Verplex, and Celestry Design. The acquisitions were apparently in part to counter the 2001 purchase of Avanti by Synopsys, as Synopsys had become their primary market rival. In 2004, Mike Fister became Cadence's new CEO and president, with Ray Bingham becoming chairman. The former chairman, Donald L. Lucas, remained on the Cadence board.WSJ [https://www.wsj.com/articles/SB108439313804409685 Intel's Michael Fister Resigns To Take Top Job at Cadence] Retrieved May 13, 2004 Between 2004 and 2007, Cadence purchased four companies, including the software developer Verisity, and in 2006, it spent $1 billion in stock buybacks.

In 2007, Cadence announced it would be introducing a new chip-making process that laid wires diagonally as well as horizontally and vertically, arguing it would make its designs more efficient. In June 2007, Cadence had a market value of around $6.4 billion. That year, Cadence was rumored to be in talks with Kohlberg Kravis Roberts and Blackstone Group regarding a possible sale of the company.[https://www.nytimes.com/2007/06/04/technology/04chip.html Specialized Software Maker Is Said to Be in Buyout Talks], Andrew Ross Sorkin and Michael J. de la Merced, The New York Times, Published: June 4, 2007 Cadence withdrew a $1.6 billion offer to purchase Mentor Graphics in 2008.{{cite web|url=http://www.cadence.com/cadence/newsroom/press_releases/Pages/pr.aspx?xml=081508_announcement|title=Cadence Withdraws Proposal to Acquire Mentor Graphics}} Also that year, Cadence's board appointed Lip-Bu Tan as acting CEO, after the resignation of Mike Fister; Tan had served on the Cadence board of directors since 2004.IConnect007 [http://design.iconnect007.com/index.php/article/30109/cadence-ceo-mike-fister-resigns/30112/?skin=design Cadence CEO Mike Fister Resigns] Retrieved October 15, 2008 In January 2009, the board of directors of Cadence voted unanimously to confirm Lip-Bu Tan as president and CEO.EETimes [https://www.eetimes.com/lip-bu-tan-named-cadence-ceo/ Lip-Bu Tan named Cadence CEO] Retrieved January 8, 2009 In 2011, it purchased Altos Design Automation.

Although most of Cadence's customers for decades were "traditional semiconductor firms," around 40% of Cadence's revenue by 2022 came from customers who were "systems" oriented, or seeking products tailored for various industries that utilized chips in a central role. Cadence was also increasingly designing customized chips for clients and having them manufactured by third parties such as Taiwan Semiconductor Manufacturing, a practice which had become more popular in the face of worldwide chip shortages and shipping issues, according to Reuters. By late 2022, Cadence had clients such as Tesla and Apple Inc.
