• 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]

FPGA synthesis

• Precision 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
• VeSys – 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
• 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 where ModelSim does not.
• Eldo is a SPICE simulator

• ADiT is a Fast-SPICE simulator
• Questa ADMS is a mixed-signal verification tool

Emulation

• The Veloce product family enables SoC emulation and transaction-based acceleration to verify and rectify issues on HDL designs prefabrication.

Mechanical design
