  • Patent number: 8984468
    Abstract: Using an adaptive square mesh for parasitic extraction, small squares of a predetermined minimum size will be placed where accuracy in the parasitic calculations is most critical—around edges, contacts and vias, and corners. Then, in areas where the parasitic analysis is less critical, for example in open spaces, a more coarse grid consisting of larger squares may be used to calculate the parasitic values in those spaces. Squares in the mesh may increase in size gradually to provide more accurate results.
