[Ghdl-discuss] Signal selection in wave

[Jonas Baggett]

Hello,

With the last git version of GHDL, there is a new --write-opt-file
option that will create a wave option file with all the signals of the
design.

Please note that there is a backward incompatible change as the
--wave-opt-file option is renamed to --read-opt-file for consistency !


Now you can do :

ghdl -r <design> --write-opt-file=trace.txt --wave=wave/toto.ghw

In order to write the path of all the signals of the design in the file
trace.txt.


Then you can edit this file and remove unneeded signals, then read it
with the following command :

ghdl -r <design> --read-opt-file=trace.txt --wave=wave/toto.ghw


Currently there is a known issue with for generates as it is impossible
to select the instantiation of a particular index, but it is planned to
be fixed.

Cheers,
Jonas

Thank you Jonas for all this work!

Hi everyone,

Recently my interest started to move from the digital design world to
Computer science, as I was doing an internship where I did C#
programming. Now I have just found recently a job in a Web development
company so it is becoming clear to me that my experiences with VHDL as
well as my implication with GHDL are now part of the past.

So I am announcing here the end of my collaboration with GHDL. I have no
regrets of that period, as I really enjoyed collaborating with you guys
and Tristan, although for a limited period of time and that I was
struggling finding the time for it. And it was the first time I was
involved on an open source project, so I have learnt a few things :-).

Have a nice day and good continuation in this project !
Jonas
