How to use verilator

Verilate:- The process of compiling a SystemVerilog/Verilog file into a binary/C++ file.

In order to observer the output of an sv/v code, we must first verilate it. This can be done using the following command:

verilator --binary <filename>.sv

To include waveform generation:

verilator --binary --trace <filename>.sv

(Note: Please include the below block in your testbench file if you want waveform generation)

initial begin
  $dumpfile(“dump.vcd”); 
  $dumpvars;
end

(Please refer to https://verilator.org/guide/latest/exe_verilator.html for more arguments like --binary and --trace)

• Once the target file has been verilated, an object will be generated in obj_dir/.
• Run the object:

./obj_dir/V<filename>

• To run waveforms:

gtkwave dump.vcd
