I just noticed the first metal 4 vccd1 rail isn't connected to the metal 1 array. I saw it in microwatt but it appears in the example project too. Not a big deal, but possibly worth fixing in openlane/openroad?

Hm, yeah, that's because it only intersects partially with the rails. A solution would be to decrease the core margin so that the rails would extend a bit more into the empty margin on the left. Another solution (for future projects) is to just increase the offset of the stripes to the right.

@Anton Blanchard are you still working on further changes, or can I pull and rerun?

Hi @jeffdi I wasn't planning to fix the above issue. I did kick off gate level tests but it ran out of disk, restarting them.
