I am getting these errors when doing tapeout job on my design. Any idea how to solve this?

@User I believe these are warnings generated from reading GDS, is that correct? Are they causing fatal errors? @User these can be ignored correct -

boundary was redefined

and

NODE elements not supported

?

Seems like so... These warnings are generated in fill_initial.log, not sure if these can be ignored or not. But I don't think this would cause fatal errors, the tapeout job can proceed and finish. I went through all the logs and these errors are the only errors I got from the tapeout job. If they can be ignored, then I am genuinely confused about what change I should make to my layout. The log only gave me a fail message without telling me where was the problem.

Hello Hongzhe, I believe you failed

tapeout

for a reason unrelated to your design, please re-submit another

tapeout

and let me know if you still get a

failed

status.

For the record, yes, the NODE and boundary messages are informational and do not represent an error. The boundary issue is that there are multiple mask layers that define the cell boundary, and I may be missing a check in magic to see if they represent the same boundary and to not complain about it if so. The NODE issue is that magic doesn't recognize this GDS record, and I have never seen it sufficiently documented to know how to handle it. It does not represent anything related to a mask layer, so ultimately it is not a problem.
