Patents by Inventor Gerald F. Plumb

Gerald F. Plumb has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8645899
    Abstract: The present disclosure is directed to a method for extracting information for a circuit design. The method may utilize an incremental extraction process for extracting information for a portion of the circuit design. Extracted results of this portion may be merged with a previously extracted result to obtain an integrated result that is equivalent to that of extracting the entire circuit design. The incremental extraction process may identify a set of changed shapes, a set of affected shapes, and a set of involved shapes for extraction. The method may also divide the circuit design into a plurality of regions, wherein two or more regions may be processed in parallel.
    Type: Grant
    Filed: March 31, 2009
    Date of Patent: February 4, 2014
    Assignee: International Business Machines Corporation

  • Patent number: 8612918
    Abstract: The present disclosure is directed to a method for extracting information for a circuit design. The method includes establishing a reflexive relationship between a plurality of design shapes corresponding to a plurality of circuit components in the circuit design. The method includes receiving a design change for at least one design shape of the plurality of design shapes. The method includes identifying a set of changed shapes, a set of affected shapes, and a set of involved shapes. The method includes extracting at least one of a capacitance, an inductance or a resistance for the updated circuit design based on at least one of the set of changed shapes, the set of affected shapes and the set of involved shapes. The method includes updating the plurality of circuit components in the circuit design based on at least one of the set of changed shapes and the set of affected shapes.
