Mentor Graphics is a US-based electronic design automation (EDA) multinational corporation for electrical engineering and electronics, headquartered in Wilsonville, Oregon. Founded in 1981, the company was acquired by Siemens in 2017. Since 2021, the former Mentor Graphics operates as a division at Siemens named Siemens EDA.

Mentor Graphics was noted for distributing 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 CAE market with its software and hardware.

History[]

Mentor Graphics was founded in 1981 by Tom Bruggere, Gerry Langeler and Dave Moffenbeier. The first round of money, worth $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 an additional $7 million. Mentor Graphics was one of the first companies to attract venture capital to Oregon.^{[citation needed]}

Apollo Computer workstations were chosen as the initial hardware platform. Based in Chelmsford, Apollo was less than a year old and had only announced itself to the public a few weeks prior to when 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. 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.^[6]

Acquisitions[]

Timeline[]

Related[]

• 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.^[22]
• In February 2011, activist investor Carl Icahn offered to buy the company for about $1.86 billion in cash.^[23]
• In November 2016, Mentor Graphics announced that it was to be acquired by Siemens for $4.5 billion,^[24] at $37.25 per share, a 21% premium on Mentor's closing price on the previous Friday.^[25] The acquisition was completed in March 2017.^[26] Mentor Graphics started to operate as "Mentor, a Siemens Business".^[27] Under the terms of the acquisition, Mentor Graphics kept its headquarters in Wilsonville with workforce intact, and operated as an independent subsidiary.^[28]
• In January 2021, Mentor became a division of Siemens and was renamed as Siemens EDA.^[29]

Locations[]

Mentor product development was located in the US, Taiwan, Egypt, Poland, Hungary, Japan, France, Canada, Pakistan, UK, Armenia, India and Russia.

Notable persons[]

James "Jim" Ready, left Mentor in 1999 to form the embedded Linux company MontaVista. Neil Henderson joined Mentor Graphics in 2002 with the acquisition of Accelerated Technology Inc. Stephen Mellor, a leader in the UML space and co-originator of the Shlaer-Mellor design methodology, joined Mentor Graphics in 2004 following the acquisition of Project Technology.

Management[]

Walden C. Rhines was the company's chief executive officer and president^[30] following the acquisition by Siemens, until November 2018 when he became CEO Emeritus. Tony Hemmelgarn is now the president and CEO of Siemens Digital Industries Software, which includes the former Mentor product line.

  • Nucleus OS (acquired in 2002 when Mentor acquired Accelerated Technology, Inc.)
  • VRTX (acquired in 1995 when Mentor bought Microtec Research)
• AUTOSAR implementation:
  • Embedded implementation in part acquired from Mecel in 2013^[32]
  • Configuration tooling Volcano Vehicle Systems Builder (VSB)
• Development Tools:
  • Sourcery CodeBench and Sourcery GNU toolchains (acquired in 2010 when Mentor acquired CodeSourcery)
  • - (Next Device was acquired by Mentor in 2006)
  • xtUML Design Tools: BridgePoint (acquired in 2004 when Mentor acquired Project Technology)
• VPN Solutions:
  • Nucleus Point-to-Point Tunneling Protocol (PPTP) software
  • Nucleus NET networking stack
  • Nucleus implementation of the Microsoft Point-to-Point Encryption (MPPE) protocol
  • Nucleus PPP software

FPGA Synthesis[]

• - Advanced RTL & physical synthesis for FPGAs

Electrical Systems, Cabling, and Harness[]

• Capital - a suite of integrated tools for the design, validation and manufacture of electrical systems and harnesses
• - a mid-market toolset for vehicle electrical system and harness design

Simulation[]

• ModelSim is a hardware simulation and debug environment primarily targeted at smaller ASIC and FPGA design
• is a simulator with advanced debug capabilities targeted at complex FPGA's and SoC's. QuestaSim can be used by users who have experience with ModelSim as it shares most of the common debug features and capabilities. One of the main differences between QuestaSim and Modelsim (besides performance/capacity) is that QuestaSim is the simulation engine for the Questa Platform which includes integration of Verification Management, Formal based technologies, Questa Verification IP, Low Power Simulation and Accelerated Coverage Closure technologies. QuestaSim natively supports SystemVerilog for Testbench, UPF, UCIS, OVM/UVM where ModelSim does not.
• Eldo is a SPICE simulator
• Xpedition AMS is a virtual lab for mechatronic system design and analysis
• is a Fast-SPICE simulator
• is a mixed-signal verification tool

  • is an electronics cooling CFD tool incorporating a solid modeler for manipulating MCAD parts.
  • Simcenter 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:
