ModelSim: Digital Circuit Simulator
ModelSim is a digital circuit simulator used for simulating and debugging HDL designs like VHDL, Verilog, and SystemVerilog. It enables functional and timing simulations of RTL designs before synthesis to verify functionality.
What is ModelSim?
ModelSim is a widely used HDL simulator and debugger for verifying digital circuit designs modeled in hardware description languages (HDL) like VHDL, Verilog, and SystemVerilog before synthesis. It allows comprehensive functional and timing simulations of RTL designs to thoroughly verify the functionality and timing performance.
Key features of ModelSim include:
- Fast and efficient event-driven simulation for large complex designs
- Supports various levels of simulation such as behavioral, functional, timing, and gate-level
- Advanced debugging features like breakpoint insertion and waveform tracing
- Supports language standards like VHDL, Verilog, SystemVerilog, PSL, and SVA
- Interoperability with major synthesis, placement and routing tools
- Scripting support to automate simulation workflows
ModelSim delivers proven technology for FPGA, ASIC and SoC design and verification. It is developed by Mentor Graphics and runs on various OS platforms like Linux, Windows and Unix workstations.
