Abstract:
1. A method for performing design layout, comprising: generating a first connectivity ring, from a first connectivity material type, within a design layout, the first connectivity ring connecting one or more ring one vias; responsive to the first connectivity ring connecting a first ring one via to a second ring one via, where the first ring one via has a net type that is different than a net type of the second ring one via, applying a first cut to the first connectivity ring to isolate the first ring one via from the second ring one via; generating a second connectivity ring, from a second connectivity material, within the design layout, the second connectivity ring comprising a second connectivity material type, the second connectivity ring connecting one or more ring two vias; and responsive to the second connectivity ring connecting a first ring two via to a second ring two via, where the first ring two via has a net type that is different than a net type of the second ring two via, applying a second cut to the second connectivity ring to isolate the first ring two via from the second ring two via, at least some of the method implemented at least in part via a computer.
