Patents by Inventor Limor Plotkin

Limor Plotkin 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: 10657211
    Abstract: Zero wire load based assertions are generated. A zero wire load report is generated for a set of logic in a hardware description language corresponding to a circuit design. A set of assertions is identified for the circuit design by parsing the zero wire load report based in part on real data values corresponding to best case delays for one or more input pins and one or more output pins in a plurality of macros of the circuit design. A circuit may be fabricated based on the set of assertions.
    Type: Grant

  • Patent number: 10572613
    Abstract: A computer system for estimating timing convergence using assertion comparisons. The computer system receives predefined golden assertions associated with a macro to be tested. The computer system executes the macro to obtain current feedback assertion values. The computer system calculates one or more metrics based on a comparison between the current feedback assertion values and values of one or more different sets of assertions. The computer system estimates a time to convergence based on the one or more calculated metrics. The computer system generates a schedule based on the estimated time to convergence.
