Frances S. M. Clougherty 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: 9383767
    Abstract: An electronic system is disclosed, which may include a phase pipeline, a data pipeline, an input phase selector, and an output phase selector. The phase pipeline may have latches clocked by a clock signal, and designed to propagate phase signals from a phase input to a phase output. The data pipeline may have latches clocked by the phase pipeline clock signal, and designed to propagate data from a data input to a data output. The input phase selector may be designed to provide an inverted or a non-inverted copy of data from a data input, in response to a value at the phase input, to the data pipeline data input. The output phase selector may be designed to provide an inverted or a non-inverted copy of data from the data pipeline output to an output phase selector data output, in response to a phase pipeline output value.

  • Patent number: 8943458
    Abstract: Various embodiments include approaches for determining burn-in workload conditions for an integrated circuit (IC) design. Some embodiments include burn-in testing the IC design using the workload conditions. In some embodiments, a computer implemented method includes obtaining survey data about at least one application workload for an integrated circuit (IC) corresponding to an IC design; generating latch state and clocking statistics about the IC design for the at least one application workload based upon the survey data; and determining a set of burn-in workload conditions for the IC design based upon the latch state and clocking statistics about the IC design.
