## History

### 1983–1999

Founded in 1983 in [San Jose, California](/source/San_Jose%2C_California),[6] Cadence Design Systems began as an [electronic design automation](/source/Electronic_design_automation) (EDA) company named Solomon Design Automation (SDA).[4] SDA's cofounders included [James Solomon](/source/James_Solomon_(engineer)), [Richard Newton](/source/A._Richard_Newton),[4] and [Alberto Sangiovanni-Vincentelli](/source/Alberto_Sangiovanni-Vincentelli).[4][7] Cadence was formed by the merger of SDA and [ECAD](/source/ECAD%2C_Inc.). A public company,[4] ECAD had been co-founded by Ping Chao, Glen Antle, and Paul Huang in 1982.[4][*[failed verification](https://en.wikipedia.org/wiki/Wikipedia:Verifiability)*] Cadence Design Systems was officially formed through the 1988 merger of SDA and ECAD,[4] with [Joseph Costello](/source/Joseph_Costello_(software_executive)) appointed both CEO and president of the newly combined company. After the merger, Cadence began trading on the [New York Stock Exchange](/source/New_York_Stock_Exchange) and Costello oversaw further mergers and acquisitions.[4]

In 1989, the company acquired [Gateway Design Automation](/source/Gateway_Design_Automation) for $72 million.[8] In 1990 it acquired Automated Systems Inc., and in doing so added "board design to its existing line of chip design software."[9] In 1991, Cadence acquired its rival [Valid Logic Systems](/source/SCALD) for around $200 million, its biggest acquisition yet. The revenues of the combined company were $390 million, according to the *New York Times.*[4]

In 1996, Cadence acquired High Level Design Systems,[10] 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.[11] Ray Bingham was named CEO in 1999.[12] Cadence purchased Ambit Design Systems for $260 million, which made tools for [system-on-a-chip](/source/System-on-a-chip) technology, in 1998,[13] and [OrCAD Systems](/source/OrCAD_Systems) in 1999.[14] Cadence acquired Quickturn Design Systems in 1999, preventing a [hostile takeover](/source/Hostile_takeover) attempt by [Mentor Graphics](/source/Mentor_Graphics).[15]

### 2000–2019

Under urging by executives such as Jim Hogan and executive vice president [Penny Herscher](/source/Penny_Herscher), between 2001 and 2003, Cadence purchased a number of implementation tools through acquisition, such as Silicon Perspective, Verplex,[16] and [Celestry Design](/source/Chenming_Hu).[17] The acquisitions were apparently in part to counter the 2001 purchase of [Avanti](/source/Synopsys#Avanti_Corporation) by [Synopsys](/source/Synopsys), as Synopsys had become their primary market rival.[16] 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.[18] Between 2004 and 2007, Cadence purchased four companies, including the software developer [Verisity](/source/Rob_A._Rutenbar), and in 2006, it spent $1 billion in [stock buybacks](/source/Stock_buyback).[6]

In 2007, Cadence announced it would be introducing a new chip-making process that laid wires diagonally as well as horizontally and vertically. 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](/source/Kohlberg_Kravis_Roberts) and [Blackstone Group](/source/Blackstone_Group) regarding a possible sale of the company.[6] Cadence withdrew a $1.6 billion offer to purchase Mentor Graphics in 2008.[19] Also that year, Cadence's board appointed [Lip-Bu Tan](/source/Lip-Bu_Tan) as acting CEO, after the resignation of Mike Fister; Tan had served on the Cadence board of directors since 2004.[20] In January 2009, the board of directors of Cadence voted unanimously to confirm Lip-Bu Tan as president and CEO.[21] In 2011, it purchased [Altos Design Automation](/source/Altos_Design_Automation).[22] Subsequent notable acquisitions included [Cosmic Circuits](/source/Cosmic_Circuits)[23] and [Tensilica](/source/Tensilica) in 2013,[24] [Forte Design Systems](/source/Forte_Design_Systems) in 2014,[25] and the [AWR Corporation](/source/AWR_Corporation) in 2019.[26]

### 2020–2025

Cadence had 9,300 employees and annual revenue of $3 billion in 2021.[5] Most of its revenue came from licensing its software and intellectual property.[27] In April 2021, following a *[Washington Post](/source/The_Washington_Post)* report on the use of Cadence and [Synopsys](/source/Synopsys) technology in the [People's Liberation Army](/source/People's_Liberation_Army)'s [military-civil fusion](/source/Military-civil_fusion) efforts,[28] U.S. legislators [Michael McCaul](/source/Michael_McCaul) and [Tom Cotton](/source/Tom_Cotton) requested that the [United States Department of Commerce](/source/United_States_Department_of_Commerce) tighten controls on the sales of semiconductor manufacturing software.[29][30] On December 15, 2021, [Anirudh Devgan](/source/Anirudh_Devgan) assumed the role of Cadence president & CEO, after having been named Cadence president in 2017. Lip-Bu Tan retired as CEO and became executive chairman[31] and left this position and the board in May 2023. In 2021, Cadence launched an [artificial intelligence](/source/Artificial_intelligence) platform to streamline processor development.[32]

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](/source/Taiwan_Semiconductor_Manufacturing), a practice which had become more popular in the face of worldwide chip shortages and shipping issues, according to [Reuters](/source/Reuters).[13] By late 2022, Cadence had clients such as [Tesla](/source/Tesla%2C_Inc.) and [Apple Inc.](/source/Apple_Inc.)[13] Cadence acquired [OpenEye Scientific Software](/source/OpenEye_Scientific_Software) for $500 million in September 2022, rebranding the company OpenEye Cadence Molecular Sciences and making it into a business unit.[5] OpenEye signed [Pfizer](/source/Pfizer) as a software client in October 2023.[33]

Cadence purchased several businesses from [Rambus](/source/Rambus) in 2023.[34] In February 2024, Cadence "quietly stepped into the supercomputer business," according to [TechRadar](/source/TechRadar), when it unveiled the M1, its own supercomputer designed to run [computational fluid dynamics](/source/Computational_fluid_dynamics) (CFD) while utilizing AI.[35] In June 2024, Cadence purchased BETA CAE Systems.[36]

In January 2025, Cadence announced the acquisition of [Secure-IC](https://fr.wikipedia.org/wiki/Secure-IC), an embedded security IP platform provider; the acquisition is expected to close by mid-2025, following the usual regulatory approvals and other closing conditions, and be immaterial to 2025 revenue and earnings.[37]

In mid-2025, the [Trump administration](/source/Second_presidency_of_Donald_Trump) briefly paused the issuing of licenses for exports of American EDA software to China, including Cadence products.[38][39] In July 2025, it was announced that Cadence would plead guilty to violating U.S. [export controls](/source/Export_controls) and pay US$140 million.[40]

On September 4, 2025, Cadence Design Systems announced it would acquire the design and engineering business of Stockholm-based [Hexagon AB](/source/Hexagon_AB) for €2.7 billion (approximately $3.16 billion) in a stock-and-cash deal.[41] The acquisition includes Hexagon's [MSC Software](/source/MSC_Software) business, a provider of engineering simulation and analysis software and workflows.[42]

## Controversies

### Lawsuits

- **Avanti Corporation** Main article: [Cadence Design Systems, Inc. v. Avanti Corp](/source/Cadence_Design_Systems%2C_Inc._v._Avanti_Corp) From 1995 until 2002, Cadence was involved in a [6-year-long legal dispute](/source/Cadence_Design_Systems%2C_Inc._v._Avanti_Corp)[154] with [Avanti Corporation](/source/Avanti_Corporation) (brand name "Avant!"), in which Cadence claimed Avanti stole Cadence code, and Avanti denied it. According to Business Week *"The Avanti case is probably the most dramatic tale of white-collar crime in the history of Silicon Valley"*.[154] The Avanti executives eventually pleaded *no contest* and Cadence received several hundred million dollars in restitution. Avanti was then purchased by [Synopsys](/source/Synopsys), which paid $265 million more to settle the remaining claims.[155] The case resulted in a number of [legal precedents](/source/Legal_precedent).[156]

- **Aptix Corporation** Quickturn Design Systems, a company acquired by Cadence, was involved in a series of legal events with Aptix Corporation. Aptix licensed a patent to [Mentor Graphics](/source/Mentor_Graphics) and the two companies jointly sued Quickturn over an alleged patent infringement. Amr Mohsen, CEO of Aptix, forged and tampered with legal evidence and was subsequently charged with conspiracy, perjury, and obstruction of justice. Mohsen was arrested after violating his bail agreement by attempting to flee the country. While in jail, Mohsen plotted to intimidate witnesses and kill the federal judge presiding over his case.[157] Mohsen was further charged with attempting to delay a federal trial by feigning incompetency.[158][159] Due to the overwhelming misconduct, the judge ruled the lawsuit as unenforceable and Mohsen was sentenced to 17 years in prison.[160] Mentor Graphics subsequently sued Aptix to recoup legal costs. Cadence also sued Mentor Graphics and Aptix to recover legal costs.[161]

- **Berkeley Design Automation** In 2013, Cadence sued Berkeley Design Automation (BDA) for circumvention of a license scheme to link its Analog FastSpice (AFS) simulator to Cadence's Analog Design Environment (Virtuoso ADE).[162] The lawsuit was settled less than one year later with an undisclosed payment of BDA and a multi-year agreement to support interoperability of AFS with ADE through Cadence's official interface. BDA was bought by [Mentor Graphics](/source/Mentor_Graphics) a few months later.[163]

### Export control violations and Chinese military university sales

In July 2025, Cadence Design Systems agreed to plead guilty to criminal charges and pay over $140 million in combined penalties for illegally exporting semiconductor design technology to China's [National University of Defense Technology](/source/National_University_of_Defense_Technology) (NUDT), a military university controlled by [China's Central Military Commission](/source/China's_Central_Military_Commission).[40] According to the [U.S. Department of Justice](/source/U.S._Department_of_Justice) and [Bureau of Industry and Security](/source/Bureau_of_Industry_and_Security), Cadence's Chinese subsidiary knowingly sold electronic design automation (EDA) hardware, software, and semiconductor design technology valued at over $45 million to NUDT between 2015 and 2021, despite the university being placed on the U.S. Entity List in February 2015 due to its use of American technology for supercomputers "believed to support nuclear explosive simulation and military simulation activities."[164][165]

The violations involved employees at Cadence's Chinese subsidiary using intermediary companies, including Central South CAD Center (CSCC) and later Phytium Technology, to disguise sales to the restricted military university.[166] Internal communications revealed that Cadence China employees were explicitly instructed to refer to NUDT only in Chinese characters and use "CSCC" in English correspondence because "the subject [was] too sensitive."[167] The Department of Justice noted that Cadence received only partial cooperation credit because the company "failed to voluntarily disclose the misconduct" and did not fully facilitate interviews of China-based employees, ultimately resulting in the company being placed on three years of corporate probation.[168]
