Abstract
An improved method and system for performing extraction on an integrated circuit design is disclosed. Extraction can be performed at granularities much smaller than the entire IC design, in which a halo is used to identify a geometric volume surrounding an object of interest to identify neighboring objects and generate an electrical model. The extraction approach can be taken for Islands, Nets, as well as other granularities within the design. Re-extraction of a design can occur at granularities smaller than a net. Some approaches utilize Island-stitching to replace an island within a net. An approach is also described for improving cross-references for cross-coupled objects.
