The Simulation Directory

Here we use iVerilog+GTKWave for simulation by default, and VCS+Verdi are also supported in simulation environment, you can choose the simulation tool by Makefile variable SIM. If you want to run simulation tests directly, please make sure these EDA tools are installed in your working environment.

Preparation

make clean

make install

Compile

make compile SIM=iverilog or make compile SIM=VCS

Run Test

make run_test SIM=iverilog or make run_test SIM=vcs

Check Waveform

make wave SIM=iverilog or make wave SIM=vcs

Note:

If you use iVerilog as simulation tool, please make sure the tool verison is 12.0.
