How to install Icarus Verilog + Gtkwave in Ubuntu Linux and test it

Icarus Verilog and Gtkwave are available in the repository of most GNU/Linux distributions, so installing them is straightforward and an ideal way to start designing digital circuits using Verilog.

This video shows how to do the installation and test of Icarus Verilog and Gtkwave in Ubuntu Linux with a "Hello World!" example. The same instructions apply to any Debian-based Linux distribution.

Thank you so much. I spent a lot of time finding a simulation open-source

Hi, I had a state machine in verilog but can't see it in gtkwake

Reg [2:0] idle = 3'b001, start = 3'b010, stop = 3'b100;

I can't see this on gtkwake, any way around?

$dumpadd() or $dumpall()

Do help if you know this thanks!
