I generated pcell using SKILL script in cadence icfb 5.1 version.
When I try to run DRC for layout with such pcell, Calibre reports error like
"ERROR: Failure to read input file xxx/test.calibre.db at record offset 0."
("xxx" is the file path and "test" is the name of the layout view)
If I flatten the pcell, however, it does not have any problem.
For this version of Cadence, the input is extracted as GDSII format.
Is anyone familiar with this problem?
In addition, if I run into same problem with newer version of Cadence that uses OA file, what should I do to solve the problem?
Thank you very much.
