Review:
Verilator (open Source Hdl Simulator)
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Verilator is an open-source hardware description language (HDL) simulator primarily used for the simulation and verification of digital circuits written in Verilog. It converts Verilog code into C++ or SystemC, enabling high-performance simulation suitable for large-scale designs and complex verification environments. Developed by Wilson Snyder and maintained actively by the community, Verilator stands out as a free, efficient alternative to proprietary HDL simulators.
