Patents by Inventor Malede W. Berhanu

Malede W. Berhanu 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: 8825433
    Abstract: A method and system is provided for automatically generating valid at speed structural test (ASST) test groups. The method includes loading a netlist for an integrated circuit into a processor. The method further includes determining a plurality of clock domain crossings between a plurality of clock domains within the integrated circuit. The method further includes generating a first test group. The method further includes adding a first clock domain of the plurality of clock domains to the first test group. The method further includes adding a second clock domain of the plurality of clock domains to the first test group when the second clock domain does not have a clock domain crossing into the first clock domain.
    Type: Grant
    Filed: September 23, 2011
    Date of Patent: September 2, 2014
    Assignee: International Business Machines Corporation

  • Patent number: 8300752
    Abstract: A structure for performing cross-chip communication with mesochronous clocks. The structure includes: a data delay line; a remote clock delay line; a structure that captures at least one value of a state of a delayed remote clock signal on the remote clock delay line; and a control that influences a delay associated with the data delay line and the remote clock delay line.

  • Patent number: 8189723
    Abstract: A method for source synchronous communication. The method includes dynamically adjusting a delay that is applied to a data signal and a remote clock signal until a delayed remote clock signal is synchronized with a local clock signal, and capturing data from a delayed data signal associated with the delay in a local domain.
