I am new to Cadence SPB/Allegro, so there may be something simple I'm missing.Originally posted in cdnusers.org by colincross
I am trying to set up some basic library components, such as an LM317 regulator. The regulator comes in two styles we may use, a TO220 with 4 pins (3 pins and the heatsink), and a D-PAK with 3 pins. In the TO220 package, pins 2 and 4 (the heatsink) are the same. I want a schematic symbol with 3 pins connected to both possible footprints.
In Part Developer, I can only connect a schematic pin to multiple footprint pins if I set it as a global pin, but then, as far as I can tell, I can't make it show up in the schematic symbol. Alternatively, I can create a footprint with the same pin number for pin 2 and the heatsink (maybe?), but then I can't reuse the footprint between components.
Is there a better solution I'm missing?
