Add option to create waveform files for GHDL (GUI mode)

[Paebbels]

Please add an option to GHDL, so waveform files in GHW format can be created. These can then be viewed and analyzed with GTKwave.

The needed option is --wave=${LibraryUnit}.ghw after the LibraryUnit.

Here a diff from my workaround:

- exec echo "$ghdl --elab-run --std=${VhdlShortVersion} --syn-binding --work=${LibraryName} --workdir=${GHDL_WORKING_LIBRARY_PATH} ${VHDL_RESOURCE_LIBRARY_PATHS} ${LibraryUnit}" | {*}[get_tee]
+ exec echo "$ghdl --elab-run --std=${VhdlShortVersion} --syn-binding --work=${LibraryName} --workdir=${GHDL_WORKING_LIBRARY_PATH} ${VHDL_RESOURCE_LIBRARY_PATHS} ${LibraryUnit}" --wave=${LibraryUnit}.ghw | {*}[get_tee]

Ideally, OSVVM scripting could offer a GUI mode / switch / variable.

• in case of a vlib/vcom/vsim interface compatible simulator: launch simulator in GUI mode.
• in case of GHDL: write a waveform file in GHW format.

With the Dev release, you can do this with SetExtendedSimulateOptions "--wave=\${LibraryUnit}.ghw"

I think it should get evaluated as a variable. We will have to test it. @Paebbels Please test the above.

[Paebbels]

Please note, --wave is a runtime option, so it must be specified after the ${LibraryUnit}.

See https://ghdl.github.io/ghdl/using/InvokingGHDL.html#elaborate-and-run-elab-run

I think this is now covered by SetExtendedSimulateOptions.

How to set a single and how to set multiple options? The documentation mentions only a single value.

Examples:

• --wave=Testbench.ghw
• --wave=Testbench.ghw --stop-time=100us

[JimLewis]

SetExtendedElaborateOptions, SetExtendedRunOptions, and SetSaveWaves were on main branch. Still have to add documentation for them.

It doesn't appear in the documentation at https://github.com/PLC2/OSVVM-Scripts/blob/main/README.rst, right?
