Abstract
Methods, systems, and computer program products are described for extracting electromagnetic characteristics from a large-scale integrated circuit. An input layout of the large-scale integrated circuit is received. The input layout includes a netlist having a plurality of segments. Groups of segments from the plurality of segments are identified based on magnetic coupling. A plurality of matrices are generated including a conductance matrix, a capacitance matrix, and an inductance matrix. Submatrices of the inductance matrix are based on the groups of segments. Each submatrix represents inductances among segments within one of the groups or representing inductances between a pair of the groups of segments. A simulation model is output based on the plurality of matrices for simulation of the large-scale integrated circuit.
