ModelSim - An efficient simulator for circuit design


ModelSim has earned a reputation as a reference tool among circuit designers due to its reliability and efficiency. Compared to the OEM versions from semiconductor vendors, the original ModelSim offers vendor independence and performance even with large codebases.

The ModelSim Plus version supports mixed-signal simulation of VHDL and Verilog, enabling more versatile design.

Important features:

  • The technology of a single simulator core enables the simulation of blocks in different languages on the same core.
  • Support for VHDL, Verilog, PSL, and SystemVerilog in design and assertions for testing.
  • An easy-to-use interface with a Tcl interface for program customization.
  • Integrated project management, source code templates, and wizards enhance the design work.
  • The Code Coverage feature enables comprehensive coverage testing.
  • Support for Xilinx SecureIP is included by default, enhancing security and reliability.
  • In addition, a SystemC option is available.

ModelSim offers additional power and flexibility when traditional solutions provided by semiconductor manufacturers are no longer sufficient. The Plus version enables mixed-signal simulation between VHDL and Verilog, making it an essential tool for circuit designers.
