Abstract
Exemplary impedance extraction methods, systems, and apparatus are described herein. In one exemplary embodiment, for instance, a signal-wire segment of a circuit layout is selected. A predetermined number of return paths are identified for the selected signal-wire segment. The selected signal-wire segment and the identified return paths are further segmented into a plurality of bundles, which comprise signal-wire subsegments and one or more associated return-path subsegments that are parallel to and have the same length as the signal-wire subsegments. Loop inductance values and loop resistance values are determined and stored for the signal-wire subsegments in the bundles for at least one frequency of operation. Computer-readable media storing computer-executable instructions for causing a computer to perform any of the disclosed methods or storing data or information created or modified using any of the disclosed techniques are also disclosed.
