Abstract:
1. A method for analyzing mutual inductance in a circuit, comprising: receiving a description of the circuit, the description being indicative of the layout of signal wires, ground wires, and power wires in the circuit; grouping at least a portion of the signal wires and the ground wires into at least a first bundle and a second bundle, the first bundle and the second bundle each comprising a respective signal-wire segment and one or more corresponding ground-wire segments; calculating a representative dipole moment for the first bundle; determining whether a distance between the first bundle and the second bundle is greater than a threshold distance; calculating a mutual inductance between the first bundle and the second bundle using the representative dipole moment, the calculating of the mutual inductance using the representative dipole moment being performed only if the distance is greater than the threshold distance; and outputting the mutual inductance.
