To change MinSpacing rule in DRD when length of metal1 is large

venuuuuu

Hi guys,

           Can I Change  MinSpacing rule in DRD when metal going in long path. What's my thought is there is two minspacing rules for Metal1. In my DRC rule file for small length path contains one spacing and large length path contain another spacing. When I activate DRD then I want to probe  marker in my layout for both values.

  • Look in the documentation. In cdsdoc (I believe from previous posts that you're using IC5141), search for "DRD". You'll find a search result Virtuoso Layout Editor Turbo User Guide -- 2. Design-Rule-Driven Editing (this was the first hit in my case). I clicked on that, and then went to the Supported Rules section. If you scroll down a bit, you'll find Minimum Spacing Parallel Run Length (as well as Minimum Spacing further up), with examples of the technology file requirements for each as well as pictures showing you what everything means.
