Does the full cell have to be a multiple of 1.2um? BIM says the metal 2 spacing should be, but is it okay for the actual cell to be slightly off?

No, the cell itself also needs to be a multiple of 1.2, because otherwise, if you adjoin two cells, and one of them is not a multiple, then all the metal2 IO no longer aligns on 1.2. On 21 Nov 2013, at 23:49, seblovett notifications@github.com wrote:
