Abstract:
1. 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 at least one design shape of the plurality of design shapes; updating, by a processor, the circuit design based on the design change; identifying, as a result of the design change, a set of changed shapes, a set of affected shapes, and a set of involved shapes, extracting at least one of a capacitance, an inductance and a resistance for the updated circuit design from at least one of the set of changed shapes, the set of affected shapes and the set of involved shapes; and updating 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.
