'''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 ==
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> 

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]].

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.<ref>''The Mentor Graphics Story'' copyright 1988 Mentor Graphics Corporation</ref>

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]].<ref>{{cite web |last1=Dahad |first1=Nitin |title=Mentor Finally Becomes Siemens EDA From January 2021 |url=https://www.eetimes.com/mentor-finally-becomes-siemens-eda-from-january-2021/ |website=EE Times|date=15 December 2020 }}</ref>

=== Mechanical design ===
*Fluid Dynamics and Heat Transfer tools:
**Simcenter Flotherm is a [[Computational Fluid Dynamics]] tool dedicated to [[electronics cooling]] using parameterized 'SmartParts' for common electronic components such as fans, [[heatsink]]s, and [[integrated circuit|IC]] packages.
**Simcenter Flotherm XT is an [[electronics cooling]] CFD tool incorporating a solid modeler for manipulating MCAD parts.
**Simcenter FLOEFD is a 'design concurrent' CFD tool for use in early-stage product design and is embedded within MCAD systems such as Solidworks, Creo Elements/Pro, CATIA V5 and Siemens NX.
*Thermal Characterization and Thermal Interface Material (TIM) Measurement equipment:
**Simcenter T3STER is a hardware product that embodies an implementation of the JEDEC JESD51-1 standard for IC package thermal characterization and is compliant with JESD51-14 for Rth-JC measurement.
**Simcenter TERALED provides automation of the CIE 127:2007 standard providing total [[flux]], [[chromaticity]] and [[correlated color temperature]] (CCT) for power [[LED]]s. With T3Ster it provides [[thermal resistance]] metrics for LEDs based on the real dissipated heating power.
**Simcenter DYNTIM extends T3Ster, providing a dynamic thermal test station for [[thermal conductivity]] measurements of thermal interface materials (TIMs), [[thermal grease]]s and gap pads.
*Simcenter Flomaster is a 1D or system-level CFD solution for analyzing fluid mechanics in complex pipe flow systems (from the acquisition of [[Flowmaster Ltd.|Flowmaster Ltd]] in 2012).
*CADRA Design Drafting is a 2-1/2D mechanical drafting and documentation package specifically designed for drafting professionals. It provides the tools needed to develop complex drawings quickly and easily (from the acquisition of the CADRA product in 2013).
