Actually, I'm having the same problem with Niall. I already enabled 'Masklayout' as Calibre view but still having the problem. This is the error message I'm seeing.
ERROR: Netlister: can't find the date lib_dir/circuit1/calibre was last extracted. None of the properties 'lastSchematicExtraction' or 'syLastExtraction' was found.
Any idea why it's happening?
Looks like this is 'check and save' related issue but I can't find 'check and save' option in layout or calibre view. It has only 'save' and I'm not sure how it's different from 'check and save' in schematic.
Calibre view was generated successfully from layout.
Thanks in advance,
