John H. Gilchrist, III 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).

  • Method and system for routing
    Patent number: 8341586
    Abstract: Disclosed is a method, system, and computer program product for routing, modeling routes, and measuring congestion. In some embodiments, Gcells are implemented with reduced number of nodes to facilitate route modeling and congestion measurement. Some embodiments are particularly suitable for direct congestion and routing analysis of diagonal routing paths. In this way, congestion analysis can be directly performed along diagonal boundaries for diagonal routes, without requiring association with Gcell boundaries on Manhattan routing layers.
    Type: Grant
    Filed: November 3, 2009
    Date of Patent: December 25, 2012
    Assignee: Cadence Design Systems, Inc.
    Inventors: Jonathan Frankle, John H. Gilchrist, III, Anish Malhotra
