ModelSim

ModelSim is a multi-language HDL simulation environment by Mentor Graphics, for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger. ModelSim is often used with Altera Quartus or Xilinx ISE.

Editions

ModelSim is offered in multiple editions, such as ModelSim PE, ModelSim SE, and ModelSim XE. ModelSim SE offers high-performance and advanced debugging capabilities, while ModelSim PE is the entry-level simulator for hobbyists and students. 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.

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

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.

ModelSim enables simulation, verification and debugging for the following languages:

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