The output files for PADS layout should include the .p file. The .p file contains an association between the PADS part type and the PADS package type. This is leftover PADS cruft from the old days when parts were produced in the same pin out for through-hole and surface mount packages. The layout engineer could change the part to surface mount in order to make his layout work better.

Anyway, having the .p file helps the layout guy avoid a bunch of work creating the part-package associations.

I suggest we work on this when we get back to writing the PHDLIF to PADS converter.

    Guys, I bumped this one up also. .p file generation is really considered necessary to go into layout. A few experienced old guys like me know how to create that in PADS but others would just discard the PHDL -> PADS flow if it is not generated by us. I sent in an example .p file a long time ago. I'm sure I can provide another one if anybody can work on it. This .p file is not as important as the problem in the .asc netlist format.
