Patents by Inventor Hannes Froehlich

Hannes Froehlich 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: 9098637
    Abstract: The present disclosure relates to a method for verifying a digital design using a computing device. The method may include determining one or more tests associated with verifying the digital design and generating, using the computing device, a verification result by performing one or more verification runs on the digital design. The method may further include merging coverage data generated by the one or more verification runs and ranking the one or more tests based upon, at least in part, a first verification run having a first configuration and a second verification run having a second configuration, wherein the first and second configurations differ.

  • Patent number: 8560985
    Abstract: In one embodiment of the invention, a method for verification of an integrated circuit design is disclosed. The method includes independently executing simulation runs in response to a plurality of coverage models to respectively generate a plurality of coverage data for a plurality of functional blocks within one or more integrated circuit designs; generating a target coverage model to selectively merge at least first coverage data associated with a first coverage model and second coverage data associated with a second coverage model; and in response to the target coverage model and the plurality of simulation runs, selectively projecting the plurality of coverage data into a merged coverage data result associated with the target coverage model. The method may further store the merged coverage data results into a storage device. The plurality of simulation runs may include at least one functional simulation run and at least one formal verification run.
