Patent ID: 8832623

Claim:
A method for generating a common design rule check (DRC) rule set for verification of a design layout, comprising: generating a common DRC rule set comprising a set of design rules derived from two or more DRC rule sets, a first DRC rule set of the two or more DRC rule sets associated with a first metal scheme and a second DRC rule set of the two or more DRC rule sets associated with a second metal scheme different than the first metal scheme, the generating comprising: for respective design rules within the set of design rules: evaluating the two or more DRC rule sets to identify a design rule constraint value for a design rule of the set of design rules based upon the design rule constraint value corresponding to a restriction threshold; and assigning the design rule constraint value to the design rule for inclusion within the common DRC rule set, at least some of the method implemented at least in part via a processing unit.
