I use Allegro/OrCAD PCB Editor for pcb design.
I have problems with irregularly shaped pins.
“Shapes” not always can be used to define padstack for such pins.
In such cases I have to add copper over the pins.
Example:
Vishay POWERPAK-1212-8 footprint requires exposed copper that overlaps partially two pins.
I would like to show 8 pins on the schematic part, so the footprint must have the same 8 pins.
I have added copper (etch) partially overlapping these pins.
I got DRC errors.
After I placed symbol on the board the DRC errors remained.
The question is: How to get rid of these errors?
Can I do something with the copper to get rid of errors, or maybe I can turn off DRCs for the specific pins (or copper) on board level.
Another example when I can't use "Shapes":
Padstack pad that are “C” shaped with the pin origin located outside the shape (beyond the copper).
I think that routing to such pin will be impossible
