View Waveforms

To use GTKWave to view a waveform:

  1. Add the following lines to your testbench to generate the dumpfiles: 
    $dumpfile("outflow/<file name>.vcd");
$dumpvars(0, sim);
  2. Simulate with the iVerilog simulator.
  3. Use this command to view the output waveform:
    gtkwave outflow/<project name>.vcd
