I am trying to understand how LibrePCB will do gate and pin swapping. Let me know if I have this right.
I create a symbol for a NAND2 gate.
I create a symbol for a power block.
I create components for a NAND2 and power block
I put a bunch of NAND2’s on a schematic with one power block for every 4 gates.
I create a component for a 74LS00 with 4 NAND2’s and a power block.
I select 4 NAND2 components and one power block and bundle them into a 74LS00.
I can now select any two NAND2 gates from any 74LS00’s and LibrePCB can swap them.
So what about pin swapping?
I create another NAND2 with swapped pins and make it a symbol variant for my NAND2 component.
Swapping pins is simply a case of selecting a gate and choosing its other symbol variant.
But if I want to swap pins after packaging I need to create 16 variants for the 74LS00 representing every possible combination of normal and swapped pins.
Is this how it will work?
