ModelSim

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

Editions

ModelSim is offered in multiple editions, such as ModelSim PE, ModelSim SE, and ModelSim XE.^[1][5]

ModelSim SE offers high-performance and advanced debugging capabilities, while ModelSim PE is the entry-level simulator for hobbyists and students.^[1] ModelSim SE is used in large multi-million gate designs, and is supported on Microsoft Windows and Linux, in 32-bit and 64-bit architectures.^[1]

ModelSim XE stands for Xilinx Edition, and is specially designed for integration with Xilinx ISE.^[5] ModelSim XE enables testing of HDL programs written for Xilinx Virtex/Spartan series FPGA's without needed physical hardware.^[5]

ModelSim can also be used with MATLAB/Simulink, using Link for ModelSim.^[6][7] Link for ModelSim is a fast bidirectional co-simulation interface between Simulink and ModelSim.^[7][6] For such designs, MATLAB provides a numerical simulation toolset, while ModelSim provides tools to verify the hardware implementation & timing characteristics of the design.^[7]

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.^[1]

ModelSim enables simulation, verification and debugging for the following languages:^[1]

• VHDL
• Verilog
• Verilog 2001
• SystemVerilog
• PSL
• SystemC
