Synopsys, Inc. is an American electronic design automation (EDA) company headquartered in Sunnyvale, California, that focuses on silicon design and verification, silicon intellectual property and software security and quality. Synopsys supplies tools and services to the semiconductor design and manufacturing industry. Products include tools for logic synthesis and physical design of integrated circuits, simulators for development, and debugging environments that assist in the design of the logic for chips and computer systems.

History

Synopsys was founded by Aart de Geus, David Gregory, Alberto Sangiovanni-Vincentelli and Bill Krieger in 1986 in Research Triangle Park, North Carolina. The company was initially established as Optimal Solutions with a charter to develop and market logic synthesis technology developed by the team at General Electric's Advanced Computer-Aided Engineering Group. The company changed its name to Synopsys and moved to Mountain View, California in 1987.{{cite magazine |last=Pretz |first=Kathy |date=March 14, 2023 |title=The Maestro Behind Design-Software Behemoth Synopsys |url=https://spectrum.ieee.org/aart-de-geus-profile |magazine=IEEE Spectrum |issn=0018-9235 |archive-url=https://web.archive.org/web/20230321204231/https://spectrum.ieee.org/aart-de-geus-profile |archive-date=March 21, 2023 |url-status=live}} It became a public company through an initial public offering in February 1992.{{cite news |url=https://www.upi.com/Archives/1992/02/26/Synopsys-backed-on-first-day-of-trading/6968699080400/ |title=Synopsys backed on first day of trading |date=February 26, 1992 |work=United Press International |archive-url=https://archive.today/20230428011626/https://www.upi.com/Archives/1992/02/26/Synopsys-backed-on-first-day-of-trading/6968699080400/ |archive-date=April 28, 2023 |url-status=live}}{{cite news |last=Smith |first=Scott S. |date=May 11, 2020 |title=Jazz Up Your Life With 'Pure Joy' Like The Synopsys CEO |url=https://www.investors.com/news/management/leaders-and-success/synopsys-ceo-find-pure-joy-work-blues/ |newspaper=Investor's Business Daily |issn=1061-2890 |archive-url=https://web.archive.org/web/20201105152820/https://www.investors.com/news/management/leaders-and-success/synopsys-ceo-find-pure-joy-work-blues/ |archive-date=November 5, 2020 |url-status=live}}

The company built a supercomputer using commodity Linux servers and off-the-shelf hardware in 2006 to develop and run EDA applications with intense computational requirements.

Avanti Corporation (styled as "Avant!") was founded when several former Cadence Design Systems employees bought the startup ArcSys, which had previously merged with Integrated Silicon Solutions (ISS),{{cite web|url=https://www.edn.com/hsu-stays-in-taiwan-for-dac/|title=Hsu Stays in Taiwan for DAC|first=Gale|last=Morrison|date=June 19, 2000|archive-url=https://web.archive.org/web/20210422185315/https://www.edn.com/hsu-stays-in-taiwan-for-dac/|website=Electronic Design News|archive-date=2021-04-22|url-status=live}} gaining Avanti its design rule checking and layout versus schematic tool Hercules (including 3D silicon structure modeling). Avanti then bought Compass Design Automation, which had fully integrated IC design flow and ASIC libraries, especially its place and route tool, which Avanti reworked to create Saturn and Apollo II. Avanti also bought TMA (Technology Modeling Associates), which brought its pioneering TCAD and Proteus optical proximity correction tools. The acquisition of Avanti was Synopsys' most significant and controversial acquisition. At the time, Avanti was the No. 4 company in the EDA industry, and was struggling with a major lawsuit from Cadence for software theft.{{cite web|url=https://www.bloomberg.com/news/articles/2001-09-02/the-avant-saga-does-crime-pay|title=The Avant!

Synopsys paid Cadence about $265 million to end that litigation. Soon after the settlement, the California Supreme Court upheld the lower court's earlier decision. Synopsys then paid $26.1 million to Silvaco to settle two of Silvaco's three lawsuits against Meta-Software, earlier purchased by Avanti, and its president. The lawsuits were filed in 1995 and inherited by Avanti.{{Cite web |url=https://www.synopsys.com/content/dam/synopsys/company/investor-relations/final8-k_73002.pdf |title=Synopsys Form 8K/A July 26, 2002 |access-date=March 6, 2021 |archive-date=October 24, 2020 |archive-url=https://web.archive.org/web/20201024152259/https://www.synopsys.com/content/dam/synopsys/company/investor-relations/final8-k_73002.pdf |url-status=live }}
