See below, an ibis file is not the cure what you think it is.

I pointed you to a mail that gives you a better tool than

One problem with ibis files as concerned with symbol files, is that
the ibis file is incomplete. Yes, you can probably get most pins out
of the ibis file, but you have to check what you are missing and add
that via another path. And if you already are adding missing pins
from another path, why don't take all pins from that path instead.

Also, ibis files probably won't give you alternate pin names or 


I can see one remote use of ibis files, and that is to make it
easier to identify what are pin tables in pdf files, but you still
have to more or less manually "help" the pin-extraction program in
some way.
