gtkw 'combined' signal #23

Open openpowerwtf opened 2 years ago

openpowerwtf commented 2 years ago

I often use the gtkwave Edit->Combine Down (F4) function to collect related signals (like valid+data) and then apply a process or transaction filter to the resulting vector.

Did I miss a way to do this with the current code?

Looks like it's similar to a trace() except uses a list of signals:
