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.

  • If you look in both the same DRD support rules part of the manual, or in the ASCII technology file syntax manual, you'll see that tableSpacingRules expects to have each rule definition in parentheses (just as you have in spacingRules and orderedSpacingRules). So you're missing a set of parentheses around the entire minSpacing rule. I don't think minSpacing has to be in quotes (I didn't try your example - not enough time) - but I'm sure it shouldn't have spaces within the quotes either.

    Actually the error message was pretty explicit as to what was wrong, especially in conjunction with the manuals.

    Andrew.
