I saw you say: "What we see is exactly what we will send to fab." and i shuddered. You are NOT seeing exactly what is sent to the fab if the gds you are looking at was made with another tool. Magic will try its best to recreate the original gds, but unless you made the techfile yourself and know EXACTLY what magic will mangle and wont mangle, you are using the wrong tool to inspect the final gds. I use the trick you are using to debug and build magic techfiles, but i wouldnt bet my job using it for final tapeouts. As for your labels, it would help if you told us what techfile you are using. My guess is you arent cifing out the labels in your cifout section. If you cant post the complete techfile, at least post the cifout layer section you are expecting labels to come out on :) -erik
