Patent ID: 8645899

Claim:
A method for extracting information for a circuit design, comprising: establishing a reflexive relationship between a plurality of design shapes corresponding to a plurality of circuit components in the circuit design; receiving a design change for a set of changed shapes of the plurality of design shapes; dividing the circuit design into a plurality of dies; splitting a split design shape of the plurality of design shapes along a boundary of a first die and a second die when a first portion of the split design shape is within the first die and a second portion of the split design shape is within the second die; identifying either the first die or the second die as a primary die that includes the set of changed shapes having the design change; identifying within the primary die the set of changed shapes, a set of affected shapes, and a set of involved shapes based on a predetermined max coupling distance; joining the first portion of the split design shape and the second portion of the split design shape; extracting at least one of a capacitance, an inductance or a resistance for the circuit design having the design change and based on at least one of the set of changed shapes, the set of affected shapes and the set of involved shapes, wherein the split design shape is within one of the set of changed shapes, the set of affected shapes and the set of involved shapes; and updating, using a computer, the plurality of circuit components in the circuit design based on at least one of the set of changed shapes and the set of affected shapes.
