problem testing gf180

[thesourcerer8]

When trying these commands:

pip install charlib git clone https://github.com/stineje/CharLib/ cd CharLib test/gf180/fetch_spice.sh charlib run test/gf180

I get this output:

Looks to me like you don't have our customized PySpice installed. We did a bit of extra work to handle the results of .measure directives and a handful of other things. This also appears to be the cause of #24 and #26.

Within the venv (or whatever equivalent you prefer) where you have CharLib installed, install our PySpice: pip install git+https://github.com/infinitymdm/PySpice. Then try running this again and see if you get some better results.

@thesourcerer8 have you had a chance to try this out with our custom PySpice version?

[thesourcerer8]

Yes, that problem seems to be gone with the correct installation of your customized version. Thanks a lot! What are your plans to distribute it upstream or to fork it?

I submitted my patches to upstream PySpice ages ago, but I think they aren't as active as they once were. Hopefully they will come back around to it and accept my PRs at some point, but until then we'll continue to point people to our customized PySpice version.
