HINTS & TIPS


Q: I run DRC, find one-two violations, correct them, then I re-run DRC to check whether my corrections worked. However re-running on the whole design is time-consuming. How can I run DRC over a piece of the layout, in the vicinity of the introduced changes?

A: Recent release of Expert contain two important features that avoid multiple batch DRC reruns for the whole design.

  • “DRC in Area” command allows you to run DRC script to be run it the selected rectangular area of the layout.
  • “DRC Guard” allows monitoring of design rule violations on the fly while editing the design.
