1983–1999

Cadence Design Systems originated in 1983 in San Jose, California as Solomon Design Automation (SDA), an EDA-focused enterprise co-founded by James Solomon, Richard Newton, and Alberto Sangiovanni-Vincentelli. The current entity emerged in 1988 following the merger of SDA with ECAD, a publicly traded company established by Ping Chao, Glen Antle, and Paul Huang. Joseph Costello assumed the roles of CEO and president of the merged organization, which commenced trading on the New York Stock Exchange. Under Costello's leadership, Cadence pursued additional mergers and acquisitions to broaden its market influence.

In 1989, Cadence expanded by acquiring Gateway Design Automation for $72 million. The subsequent year saw the purchase of Automated Systems Inc., which introduced board design capabilities to its chip design software lineup. The company’s largest acquisition at that time occurred in 1991 with the purchase of rival Valid Logic Systems for approximately $200 million. This move boosted revenues to $390 million and positioned Cadence as the foremost supplier of software tools for electronic engineers engaged in chip and circuit board design.

By 1996, after integrating High Level Design Systems into its operations, Cadence had grown to a workforce of 3,300 employees and generated annual revenue of $742 million. Leadership changes followed when Costello stepped down in 1997; Jack Harding took over as CEO before being succeeded by Ray Bingham in 1999. During this timeframe, Cadence acquired Ambit Design Systems in 1998 for $260 million to enhance its system-on-chip technology portfolio and acquired OrCAD Systems in 1999. That same year, Cadence also purchased Quickturn Design amid a hostile takeover contest with competitor Mentor Graphics, further solidifying its position within the EDA sector.

2000–2019

From 2001 through 2003, under executives such as Jim Hogan and EVP Penny Herscher, Cadence strategically acquired multiple implementation tool companies including Silicon Perspective, Verplex, and Celestry Design. These acquisitions were partly aimed at countering Synopsys’ purchase of Avanti, a primary competitor. In 2004, Mike Fister was appointed CEO and president while Ray Bingham served as chairman; former chairman Donald L. Lucas continued his role on the board. Between 2004 and 2007, Cadence completed four acquisitions notably including software firm Verisity, alongside executing stock repurchases totaling $1 billion in 2006.

In 2007, Cadence introduced an improved chip manufacturing process designed to boost design productivity. With a market capitalization near $6.4 billion that year, rumors circulated about potential buyout discussions involving Kohlberg Kravis Roberts and Blackstone Group. However, Cadence retracted a $1.6 billion offer to acquire Mentor Graphics in 2008. Following Mike Fister’s departure as CEO that year, board member Lip-Bu Tan was named interim CEO before being officially appointed president and CEO in January 2009.

The company sustained expansion through acquisitions such as Altos Design Automation in 2011; Cosmic Circuits and Tensilica in 2013; Forte Design Systems in 2014; and AWR Corporation in 2019—each acquisition reinforcing its product lineup and strengthening its standing within the electronic design automation industry.
