Pin swapping in PCB

[paulvdh]

There is a bit of a problem with this:

@glenenglish

Suppose I am routing a diff pair, and I get to the ‘end’ and the _P and _N pads are transposed - that is, my diff pairs would need to cross each other to connect to the pads.

If you swap the connections of a differential pair, then your circuit very likely does not work anymore.

For the rest, pin & gate swapping is (not yet) directly supported in KiCad. The topic below has some more background (Work around by changing the schematic and forward annotation) and a link to an open issue on gitlab.

Units swap other pins swap

Good morning everyone, my question is simple, I want to understand if during the placement of the components on the PCB it is possible to swap between equivalent Pins and/or equivalent Slots.To make my request clearer I give an example:Suppose we have a 74hc32 component. This OR component has four Slots (A, B, C, D), When placing the component, I may need to optimize the paths of the tracks, to exchange slot A with C and B with D, in addition to avoid annoying intersections,you may decide to swa…
