I see you solved this pin number issue one way, but there is another way (as
usual). If the mounting pins are not to be tied to any trace for any reason
whatsoever, then the pads can be added as a mechanical pin (these would not
have a pin number) so your logic will have only 14 pins and your physical will
have the same 14 pins with 2 mounting pads in addition. It is basically the
same as having a connector with NPTH holes for nylon mounting pegs.

Entry HDL schematic symbol...
Hi,
I have a 14 pin connector that has 16 pins in the footprint. Two of the
pins are not electrical, and are for mounting holes.
In DxD I would just set these as no-connect pins in the schematic symbol,
so that the number of pins on the schematic symbol matched the number of
pins on the PCB footprint. They were not visible, and done as attributes.
How can I do this with Allegro Design Entry?
Version is 15.7.
Thanks!
Austin
