I've seen lots of people ask more or less the same question, some even exactly my problem, but I haven't seen a solution or workaround.
I'd like to make a Raspberry Pi hat. The 2x20 pin connector that connects my hat's PCB to the Pi's GPIO connector has multiple pins on the same net. They are connected internally to the Pi, and I do **_NOT_** want to connect them also externally (to avoid ground loops and other nasties; arguing about the propriety of this is no help). Specifically, for example, pin 1 and pin 17 are both on the 3.3VDC net; they are already connected inside the Pi, and I do **_NOT_ **want to duplicate this circuit by connecting the pins externally. Worse, I want to route traces in the area that the autorouter insists on blocking by routing a wholly unwanted track between these two pins.
I'm aware of this:
Has it been fixed/added? Is there a workaround that I'm missing?
