Patents by Inventor William James Hurley

William James Hurley 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: 7475308
    Abstract: A method, apparatus and computer program product are provided for implementing deterministic based broken scan chain diagnostics. A deterministic test pattern is generated and is loaded into each scan chain in the device under test using lateral insertion via system data ports applying system clocks. Then each scan chain is unloaded and a last switching latch is identified. The testing steps are repeated a selected number of times. Then checking for consistent results is performed. When consistent results are identified, then the identified last switching latch is sent to a Physical Failure Analysis system.
    Type: Grant
    Filed: April 11, 2008
    Date of Patent: January 6, 2009
    Assignee: International Business Machines Corporation

  • Patent number: 7225374
    Abstract: An apparatus, program product and method utilize an ABIST circuit provided on an integrated circuit device to assist in the identification and location of defects in a scan chain that is also provided on the integrated circuit device. In particular, a defect in a scan chain may be detected by applying a plurality of pattern sets to a scan chain coupled to an ABIST circuit, collecting scan out data generated as a result of the application of the plurality of pattern sets to the scan chain, and using the collected scan out data to identify a defective latch in the scan chain.
