  • Patent number: 10482206
    Abstract: The present disclosure relates to a method for electronic design verification. Embodiments may include receiving, using a processor, at least one electronic design file and a set of inputs from a user, wherein the at least one electronic design file and set of inputs are associated with an electronic design. Embodiments may further include performing formal verification on at least a portion of the electronic design and determining, using a model checker, one or more conflicts associated with a variable during the formal verification. Embodiments may also include translating the one or more conflicts into one or more corresponding signal names and displaying, at a graphical user interface, the corresponding signal names.

  • Patent number: 9934410
    Abstract: A formal verification approach verifies data access and data propagation paths in a circuit design by proving the unreachability of path cover properties of the circuit design. A security path verification system receives an original circuit model of a circuit design, along with parameters identifying a first location within the circuit design that is a source of tainted data and a second location within the circuit design that is coupled to the first location. The security path verification system also receives a selection of portions of the circuit design to be excluded from the verification analysis. Using an abstracted version of the exclude portions, the security verification system generates a second circuit model of the circuit design for use in determining whether the tainted data can reach the second location from the first location within the circuit design.
