Abstract
Aspects of the disclosed technology relate to techniques of parasitic extraction. A signature for a set of geometric elements of a layout design is computed based on contour-related information. The set of geometric elements corresponds to a net of connected equipotential interconnects of a circuit design. Based on comparing the signature with signatures for sets of geometric elements that have computed parasitic element values, parasitic element values for the set of geometric elements are determined.
