Limit which variables to dump to waveform file #1103
Description
Building on #1101
NVC has --include=glob, --exclude=glob
GHDL takes a filename that includes the names: https://ghdl.github.io/ghdl/using/Simulation.html#cmdoption-ghdl-read-wave-opt
It would be convenient to specify this per testbench somehow, independent of simulator. With support for other simulators, that will also be of benefit there.
Slightly related are ghdl/nvc.viewer.gui and ghdl/nvc.viewer_script.gui in the sense that those are most likely independent of simulator. Hence, one may consider if there is a different naming scheme that can be used for these open source simulators. (Possibly all simulators, as there are use cases for that. Custom HDLs have special support in e.g. Surfer, so simulating Spade using ModelSim, it is still better to open Surfer after the simulation from some aspects. Although maybe a fringe use case. )
