@User: "Unknown keyword" messages are from Magic, which does not parse them because it has no use for them. "Fatal errors" are magic's rather annoying way of reporting what are clearly non-fatal errors during extraction, such as seeing a FET with source and drain tied together; My job is probably to get magic to stop reporting these problems as "fatal"; @User: Probably it would be a good idea after doing extraction, to select the cell and run "feedback why" to get a printout of all warnings/errors from extraction in the output file. That would go a long way towards allaying fears that something has gone badly wrong during extraction, which almost certainly hasn't happened.
