'''Mentor Graphics, Inc''' ({{NASDAQ|MENT}}) is a [[United States|US]]-based multinational [[corporation]] dealing in [[electronic design automation]] (EDA) for [[electrical engineering]] and [[electronics]], as of 2004, ranked third in the EDA industry it helped create. The company, founded in 1981, is headquartered in [[Wilsonville, Oregon]], and employs 4,000 people worldwide.
'''Mentor Graphics Corporation''' was a [[United States|US]]-based [[electronic design automation]] (EDA) [[multinational corporation]] for [[electrical engineering]] and [[electronics]], headquartered in [[Wilsonville, Oregon|Wilsonville]], Oregon. Founded in 1981, the company distributed products that assist in [[electronic design automation]], simulation tools for analog mixed-signal design, [[VPN]] solutions, and [[fluid dynamics]] and heat transfer tools. The company leveraged [[Apollo Computer]] [[workstation]]s to differentiate itself within the [[computer-aided engineering]] (CAE) market with its [[software]] and [[Computer hardware|hardware]].


Mentor Graphics was acquired by [[Siemens]] in 2017. The name was retired in 2021 and renamed '''Siemens EDA''', a segment of [[Siemens Digital Industries Software]].
==History ==


== History ==
In 1981, the idea of [[computer-aided design]] for electronics as the foundation of a company occurred to several groups - those who founded Mentor, [[Valid Logic Systems]], and [[Daisy Systems]]. One of the main distinctions between these groups was that the founding engineers of Mentor, whose backgrounds were in [[software development]] at [[Tektronix]], ruled out designing and manufacturing proprietary computers to run their software applications. They felt that [[hardware]] was going to become a commodity owned by big computer companies, so instead they would select an existing computer system as the hardware platform for the [[Computer Aided Engineering]] (CAE) programs they would build.
Mentor Graphics was founded in 1981 by [[Tom Bruggere]], Gerry Langeler, and Dave Moffenbeier, all formerly of [[Tektronix]].<ref name="OLHistory">{{cite web |last1=Rogoway |first1=Mike |title=Siemens completes $4.5 billion purchase of Mentor Graphics |url=https://www.oregonlive.com/silicon-forest/2017/03/siemens_completes_45_billion_p.html |website=Oregon Live |access-date=November 4, 2022 |date=March 30, 2017}}</ref> The company raised $55 million in funding through an [[initial public offering]] in 1984.<ref name="OLHistory"/>


Mentor initially wrote software that ran only in [[Apollo Computer|Apollo]] workstations.<ref name="NYTapollo">{{cite news |last1=Fisher |first1=Lawrence M. |title=In Hot Pursuit of Mentor Photos of Mentor's chief executive, Thomas H. Bruggere, with the package deal: Software by Mentor Graphics, running on Apollo hardware (NYT/Brian Drake); the chassis of an Apollo workstation, which uses Mentor's software system |work=The New York Times |date=8 January 1989 |url=https://www.nytimes.com/1989/01/08/business/hot-pursuit-mentor-photos-mentor-s-chief-executive-thomas-h-bruggere-with.html |access-date=November 4, 2022}}</ref>
By February 1981, most of the start-up team had been identified; by March, the three executive founders, [[Tom Bruggere]], Gerry Langeler and Dave Moffenbeier had left Tektronix, and by May the business plan was complete. The first round of money, $1 million, came from Sutter Hill, Greylock, and Venrock Associates. The next round was $2 million from five venture capital firms, and in April 1983 a third round raised $7 million more. Mentor Graphics was one of the first companies to attract venture capital to Oregon.


When Mentor entered the CAE market the company had two technical differentiators: the first was the software {{En dash}} Mentor, Valid, and Daisy each had software with different strengths and weaknesses. The second, was the hardware {{En dash}} Mentor ran all programs on the Apollo workstation, while Daisy and Valid each built their own hardware. By the late 1980s, all EDA companies abandoned proprietary hardware in favor of workstations manufactured by companies such as Apollo and [[Sun Microsystems]].
[[Apollo Computer]] workstations were chosen as the initial hardware platform. Based in Chelmsford, Massachusetts, Apollo was less than a year old and had only announced itself to the public a few weeks before the founders of Mentor Graphics began their initial meetings.

When Mentor entered the CAE market the company had two technical differentiators. The first was the software - Mentor, Valid, and Daisy each had software with different strengths and weaknesses. The second was the hardware - Mentor ran all programs on the Apollo workstation, while Daisy and Valid each built their own hardware for schematic capture, but ran simulation and other programs on larger computers such as the [[MicroVAX]].

== Acquisitions ==
Mentor Graphics is a global company with product development being done in the USA, Europe, Japan, Pakistan, India and Egypt. In keeping with global trends in software development, the company has a substantial labor force in lower cost locations such as Pakistan, India, Poland, Hungary and Egypt.
[[James Ready|James "Jim" Ready]], one of the more colorful people in [[embedded system]]s, left Mentor in 1999 to form the embedded [[Linux]] company [[MontaVista]]. Neil Henderson, a pioneer in the royalty-free, source provided market space, joined Mentor Graphics in 2002 with the acquisition of Accelerated Technology Inc. [[Stephen J. Mellor|Stephen Mellor]], a leader in the UML space and co-originator of the [[Shlaer-Mellor]] design methodology, joined Mentor Graphics in 2004 with the acquisition of Project Technology.


=== Timeline ===
As of 2010, Mentor's major competitors are [[Cadence Design Systems]], [[Synopsys]] and [[Magma Design Automation]].

Mentor Graphics Corporation was a US-based electronic design automation (EDA) multinational corporation for electrical engineering and electronics, headquartered in Wilsonville, Oregon. Founded in 1981, the company distributed products that assist in electronic design automation, simulation tools for analog mixed-signal design, VPN solutions, and fluid dynamics and heat transfer tools. The company leveraged Apollo Computer workstations to differentiate itself within the computer-aided engineering (CAE) market with its software and hardware.

Mentor Graphics was acquired by Siemens in 2017. The name was retired in 2021 and renamed Siemens EDA, a segment of Siemens Digital Industries Software.

History

[edit]

Mentor Graphics was founded in 1981 by Tom Bruggere, Gerry Langeler, and Dave Moffenbeier, all formerly of Tektronix.[6] The company raised $55 million in funding through an initial public offering in 1984.[6]

Mentor initially wrote software that ran only in Apollo workstations.[7]

When Mentor entered the CAE market the company had two technical differentiators: the first was the software – Mentor, Valid, and Daisy each had software with different strengths and weaknesses. The second, was the hardware – Mentor ran all programs on the Apollo workstation, while Daisy and Valid each built their own hardware. By the late 1980s, all EDA companies abandoned proprietary hardware in favor of workstations manufactured by companies such as Apollo and Sun Microsystems.

After a frenzied development, the IDEA 1000 product was introduced at the 1982 Design Automation Conference, though in a suite and not on the floor.[8]

Mentor Graphics was purchased by Siemens in 2017. The name was retired in 2021 and renamed Siemens EDA, a segment of Siemens Digital Industries Software.[9]

[edit]
  • In June 2008, Cadence Design Systems offered to acquire Mentor Graphics in a leveraged buyout. On 15 August 2008, Cadence withdrew this offer quoting an inability to raise the necessary capital and the unwillingness of Mentor Graphics' Board and management to discuss the offer.[26]
  • In February 2011, activist investor Carl Icahn offered to buy the company for about $1.86 billion in cash.[27]
  • In November 2016, Mentor Graphics announced that it was to be acquired by Siemens for $4.5 billion,[28] at $37.25 per share, a 21% premium on Mentor's closing price on the previous Friday.[29] The acquisition was completed in March 2017.[30] At this time, this represented Siemen's biggest deal in the industrial software sector.[31] Mentor Graphics started to operate as "Mentor, a Siemens Business".[32] Under the terms of the acquisition, Mentor Graphics kept its headquarters in Wilsonville with workforce intact, and operated as an independent subsidiary.[1]
  • In January 2021, Mentor became a division of Siemens and was renamed as Siemens EDA.[33]
