Batch Mode DRC

You can run Calibre DRC in batch mode. To do this, you need to make a rule deck. A common one would be:

LAYOUT PATH  "invx1.calibre.db"
LAYOUT PRIMARY "invx1"
LAYOUT SYSTEM GDSII
DRC RESULTS DATABASE "invx1.drc.results" ASCII 
DRC MAXIMUM RESULTS 1000
DRC MAXIMUM VERTEX 4096
DRC CELL NAME NO
DRC SUMMARY REPORT "invx1.drc.summary" REPLACE HIER
VIRTUAL CONNECT COLON NO
VIRTUAL CONNECT REPORT NO
DRC SELECT CHECK

Then you just run:

calibre -drc -hier -nowait mydrc.rul

The output is put in "invx1.drc.summary"
