I'm working with Signalstorm library characterizer. I do:
db_install (works)
db_gsim (FAILS) I get the message:
[WARNING(db_gsim)]BUFBD1 : illegal instance is found

=> no simulation

Does anyone knows what this message means? I can't figure it out. I
think it has something to do with the spectre-models because when I use
other ones I don't get this warning

Thanks

You might want to check the gate file that to check if slc identfies
the logic correctly or no. You can use the dg_gate command. According
to the documentation there is no BUFBD1 type of a cell, but there are
BUFIF0 and BUFIF1. If this is the error, then you can make corrections
in the gate file and then run db_gsim again on the modified gate file.

There is a section on Making gate file corrections in the document that
you would want to look at.

hope that helps.
