parser error when current probe present #2

Closed JoopBanaan closed 3 years ago

JoopBanaan commented 3 years ago

When adding in the Spectre output a current probe, psf-utils fails with a parser error. When not adding a current in the result, only voltages, all works fine.

Spectre seems to be producing a variant of the PSF file that I have not seen before. Would you please send me the PSF file so I can try to adapt psf-utils to handle this variant.

Hi Ken, Thanks for the fast response. Attached the tran.tran.tran file with extension changed to .log to allow upload tran.tran.log

KenKundert commented 3 years ago

Okay, I think I fixed it. Can you get the latest version from github and make sure it works for you.

JoopBanaan commented 3 years ago

Indeed you fixed it. Thanks a lot
