The reason why Verilator is so fast is fundamentally because it translates Verilog/System Verilog into C++ (or System C) code. Then it uses standard, highly efficient C++ compiler to produce natively executable “model” or program of the design (known as Device-Under-Test or DUT). Simulation...

Note: The test bench is using Icarus Verilog. However, Icarus Verilog 0.9.7 (the latest release at the time of writing) has a few bugs that prevent the test bench from running. Upgrade to the latest github master of Icarus Verilog to run the test bench. ...
