Mentor Graphics Modelsim

Mentor Graphics ModelSim is a popular simulation and debugging tool used for verifying hardware designs written in hardware description languages (HDLs) like VHDL, Verilog, and SystemVerilog. It is primarily used for functional and timing simulation, allowing designers to test and verify digital logic designs at various stages of the design cycle.

ModelSim provides an intuitive interface for waveform viewing, debugging, and analyzing simulation results, helping to identify and correct design errors early in the development process. It integrates well with other EDA tools and supports mixed-language simulation, making it versatile for complex designs. Its ability to handle both pre- and post-synthesis simulations makes it essential for FPGA and ASIC development, ensuring design correctness before hardware implementation.
