ModelSim

ModelSim is a multi-language environment by Siemens[1] (previously developed by Mentor Graphics,[2]) for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger.[3][2] ModelSim can be used independently, or in conjunction with Intel Quartus Prime, PSIM,[4] Xilinx ISE or Xilinx Vivado.[5] Simulation is performed using the graphical user interface (GUI), or automatically using scripts.[6]

Editions

Mentor HDL simulation products are offered in multiple editions, such as ModelSim PE and Questa Sim.

Questa Sim offers high-performance and advanced debugging capabilities, while ModelSim PE is the entry-level simulator for hobbyists and students.[2] Questa Sim is used in large multi-million gate designs, and is supported on Microsoft Windows and Linux, in 32-bit and 64-bit architectures.[2]

ModelSim can also be used with MATLAB/Simulink, using Link for ModelSim.[7][8] Link for ModelSim is a fast bidirectional co-simulation interface between Simulink and ModelSim.[8][7] For such designs, MATLAB provides a numerical simulation toolset, while ModelSim provides tools to verify the hardware implementation & timing characteristics of the design.[8]

Language support

ModelSim uses a unified kernel for simulation of all supported languages, and the method of debugging embedded C code is the same as VHDL or Verilog.[2]

ModelSim and Questa Sim products enable simulation, verification and debugging for the following languages:[2]
