@User (@User): I have a layout of DRC errors which would work well for unit tests except that I have one layout per rule set whereas what we need is two layouts per individual rule---one in error, and one not (and there will need to be multiple examples of each describing different ways of violating the rule or creating clean layout). I've seen layout files of pass/fail errors for most processes, but I've never seen it done in a way that could be automated; it's always lots of examples scattered around a page of layout.
