adder.vhd is the VHDL definition of your circuit.

You need to simulaate that with ghdl, and pass the output from ghdl into
gtkwave.

Its been a long time since I played wtih ghdl, but vaguely recall that
you have to call it a number of different times with different options.

You end up with a compled test-bench for your circuit, which you can
execute and get VCD output suitable for feeding gtkwave.


Hope this helps, even if I don't know ghdl enough to be of further
specific assistance.

Best wishes,
