Abstract
Exemplary impedance extraction methods, systems, and apparatus are described herein. In one exemplary embodiment, at least a portion of a circuit description indicative of a circuit layout is loaded. A signal-wire segment is selected. Loop inductance values and loop resistance values for the signal-wire segment are determined at at least a first frequency of operation and a second frequency of operation. Values for one or more inductance components and one or more resistance components of a broadband representation of the signal-wire segment are computed and stored. In this embodiment, the broadband representation comprises at least one but no more than two parallel-coupled resistance components and inductance components. 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.
