Sorry if this is an obvious question, but I have been unable to find the “right” way to do this.
I do work for a university physics lab, and have been asked to create a experimental setup (the existing ones are done on strip board) based on a schematic like diagram in the course lab manual.
There are several banana sockets in the lab schematic labeled “A”, “B”, etc. and I would like the footprint on the PCB to have the same reference.
Even though I can give the schematic component the reference/annotation “A”, when I later create the netlist for the PCB tool, even though the “Keep existing annotation” box is checked, the schematic netlist tool insists on adding a 1 after the letter, so I get “A1”, “B1” etc. placed on the PCB (And the schematic is updated with this new designator.
I know I can hide the references on the PCB and enter dumb text, but I would like to do this properly so that anyone updating the design after me doesn’t have problems.
