Has anyone been able to get source browsing to work with gtkwave?

Ideally, I'd like to have Chisel source browsing from within gtkwave...

I tried and failed to get this working. The article talks about xml2stems not really being maintained.

I've gotten as far as seeing that GTKWave supports this and thinking it would be cool to add it...

High level: this is probably doable without xml2stems and doing the analysis in a late-running FIRRTL transform. E.g., you run a transform that packages all the Info fields (which are the source locators) into a stems file.

This probably isn't that hard to do if you know what the format of the Stems file should be.

Would be super cool, I think.

I have looked at the xml2stems and my thinking is that it would not be much code in Scala and probably quite robust. So... FIR+xml from verilator and out pops a stems file. I am not sure the xml from Verilator is required to link Chisel to rtlbrowse.
