@Kareem Farid I noticed your update to the gf180mcu openlane config:

+set ::env(GPL_CELL_PADDING) {0}
+set ::env(DPL_CELL_PADDING) {2}

I know why we did this on sky130hd (because any non zero global padding would break a bunch of designs), but this is going to make dpl work harder than it needs to. @Matt Liberty wouldn't we want to have a larger global placement padding (eg 3 or 4)?

GPL padding should always be greater than or equal to DPL padding.

Thanks @Anton Blanchard. I think this helped initially getting some designs running. I agree that in the long run we need to change it

There is no need to copy the same over to gf180. I would be curious to know what design it helps as I think of it as uniformly bad practice.
