Mentor Graphics was founded in 1981 byTom Bruggere, Gerry Langeler, and Dave Moffenbeier, all formerly ofTektronix.[6] The company raised $55 million in funding through aninitial public offering in 1984.[6]
Mentor initially wrote software that ran only inApollo 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 andSun Microsystems.
After a frenzied development, the IDEA 1000 product was introduced at the 1982Design Automation Conference, though in a suite and not on the floor.[8]
In June 2008,Cadence Design Systems offered to acquire Mentor Graphics in aleveraged 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 investorCarl 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 bySiemens 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 the time, this represented Siemens' 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]
Integrated circuit layout full-custom andschematic-driven layout (SDL) tools such asIC Station orMemory Builder, a first industry tool for rapid embedded memory design that helped to develop single- or dual-portRAM (synchronous andasynchronous), as well as diffusion and metal read only memories (ROM)
ModelSim is a hardware simulation and debug environment primarily targeted at smaller ASIC and FPGA design
QuestaSim 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 whereas ModelSim does not.
Simcenter Flotherm XT is anelectronics 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 DYNTIM extends T3Ster, providing a dynamic thermal test station forthermal conductivity measurements of thermal interface materials (TIMs),thermal greases 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 ofFlowmaster 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).
