  • Systems and methods for automatic formal metastability fault analysis in an electronic design
    Patent number: 10769008
    Abstract: The present disclosure relates to a computer-implemented method for use in an electronic design. The method may include receiving, using at least one processor, an electronic design and analyzing the electronic design. The method may further include generating one or more preconditions representative of metastability effects at the output of at least one synchronizer associated with the electronic design. The method may also include generating, based upon, at least in part, the one or more preconditions, one or more properties configured to analyze a propagation of the metastability effects associated with the at least one synchronizer.

  • Methods, systems, and computer program product for verifying an electronic design
    Patent number: 9858372
    Abstract: Disclosed are techniques for implementing formal verification of an electronic design. These techniques identify a target property for verification in a hierarchical electronic design that has a plurality of hierarchies and perform hierarchical synthesis on a hierarchy or a portion thereof in the plurality of hierarchies while black-boxing a remaining portion of the hierarchical electronic design. Cone of influence (COI) data that is relevant to the target property may be determined at least by extracting the cone of influence data from a hierarchically synthesized hierarchy or portion of the hierarchy or the portion thereof. At least the cone of influence data may be forwarded to a formal engine that uses the cone of influence data to verify the target property.
