Extracting High Frequency Impedance In A Circuit Design Using An Electronic Design Automation Tool

View page
US Patent:
7689962, Mar 30, 2010
Filed:
Feb 8, 2007
Appl. No.:
11/704588
Inventors:
Roberto Suaya - 38240 Meylan, FR
Rafael Escovar - 38000 Grenoble, FR
Shrinath Thelapurath - Wilsonville OR, US
Salvador Ortiz - 38000 Grenoble, FR
Dusan Petranovic - Cupertino CA, US
International Classification:
G06F 17/50
US Classification:
716 10, 716 4
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.

US Patent:
20070225925, Sep 27, 2007
Filed:
Feb 8, 2007
Appl. No.:
11/704470
Inventors:
Roberto Suaya - Meylan, FR
Rafael Escovar - Grenoble, FR
Shrinath Thelapurath - Wilsonville OR, US
Salvador Ortiz - Grenoble, FR
International Classification:
G06F 19/00
US Classification:
702057000, 702001000, 324600000
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.
