AD Is there any good way to connect the pins in the PCB and then update it to the schematic? [Copy link]

I have a chip with many pins. To facilitate routing, I want to connect the pins of the peripherals to it in the PCB, and then update it to the schematic. For example, the main chip U1 is connected to U2. The pins of U2 are already labeled, and the Netlabels are A, B, C, and D. U1's pins 1, 2, 3, and 4 only have wires, but no Netlabels. What I do now is to draw the pins of U2 to U1, for example, to route A to the vicinity of pin 1, and then change the Netlabel of pin 1 to A, and then connect the wire of A to pin 1. Reverse update the schematic, so that U1's pin 1 will have Netlabel "A". However, this always feels very troublesome. I wonder if there is a better way, such as allowing me to connect wire A to NotLabel pin 1 in the PCB (it is now automatically avoided). It would be best if pin 1 could automatically change NotLabel to NetLabelA of the corresponding wire, so that there would be fewer steps to operate.

Reverse to the schematic diagram, if U1 adds more components, it is faster to add Netlabel to each pin. It is better to modify the schematic diagram directly and update the PCB.

After all, the U1 component is required in the schematic diagram to reverse.

AD itself has the function of swapping pins. Place the Net Labels of the two chips at will on the schematic diagram. You can freely swap the pin networks when wiring. You can connect them in any order, and then update them back to the schematic diagram in reverse.

Place a component on the PCB. This component has no Net Label, and of course the rules do not allow its pins to be connected to other existing Net Labels.

Then, it is definitely possible to add it manually, but how can I automatically add Net Labels to multiple pins of this new component, and then update it to the schematic diagram in reverse?

The so-called free swap pin network can do this? Which version

Put the Net Label normally in the schematic, and then swap it in the PCB. It should be available in version 13 and above.

Thanks, this method is very useful
