not sure why this is happening

You seem to have hand-placed the

clkbuf_4

cells because the cells are too far apart to be abutting on their abutment boxes. I expect that they might be vertically shifted by 5nm (one internal unit, or one manufacturing grid unit) which causes the 5nm local interconnect spacing errors.

how would I unshift it by 1 unit

@Rita Did you solve this? I was thinking that maybe your cell has been duplicated and offset by 1 unit. Try selecting and deleting and then maybe replacing.

I talked with tim and we came to the conclusion that it was becuase I accidentally opened the file with the wrong tech (I didn't load the config file), and it snapped everything to the nearest 0.01 um instead of the 0.005um for the SKY130A process
