command line calibre
Hello,
calibre -hier -drc : performs hierarchial design rule checking by maintaining the database
hierarchy to reduce processing time, memory usage, and DRC result counts. Calibre DRC-H
imposes no design restrictions on shapes overlapping cell placements, or overlaps of cell
placements.
calibre -drc: performs flat design rule checking by reading the database flat and
operating on the resultant flat shapes.
Hope this helps you.
