I’m wondering what is the correct way to represent say a power supply, whose connector footprint has more than one ground pin or power output pin. Sometimes this is necessary to reduce current limitations.
I get an ERC error because my custom symbol has more than one pin labeled GND as power outputs. This is representing an off-board connector for which I want to use several wires in a ribbon cable to transfer power.
The footprint could I suppose just have duplicate pads of the same pin number, but I’d like to use the standard unmodified IDC footprint and just have a functional symbol to keep consistent my interface definition. Accordingly I have the opposite connector/interface defined for which there is no problem as the multiple ground power inputs don’t conflict.
Edit : I found this link clarifying my problem. It looks to me like there isn’t a real workaround, stacking pins seems like a bad idea for schematic readability, marking the other as passive yields ERC errors if you drive GND from only the passive pin.
