It is a good idea that the Librarian do a Purge when a physical is created. It
will get rid of any old padstacks that may have been copied if the physical was
created from
a previous part. It will also solve Padstack not found issues if a part is
copied from on old design.

Thanks so much Bill, it worked like a charm!!
I have used Modify Design Padstack many times, but never even noticed the
Purge-> button at the bottom of the Options tab.
So you work for Sun (as in Microsystems)? I have fond memories of Sun
Workstations, we used them back in the old days when Allegro was run on UNIX.
Thanks again for solving this one for me (along with Barbara's help, of
course!). I'm going to stash your e-mail away for future reference.

Hi Gary,
Have you done: Tools > Padstack > Modify Design Padstack > Purge > All
If not, try that and then flash_convert again.
Let me know if the flash_convert.log still complains about unused pads.
