Verilator: Technology, History, Applications & Products

Verilator is a software programming tool which converts the hardware description language Verilog to a cycle-accurate behavioral model in the programming languages C++ or SystemC. The generated models are cycle-accurate and 2-state; as a consequence, the models typically offer higher performance than the more widely used event-driven simulators, which…
