  • Signal reconstruction in sequential logic circuitry
    Patent number: 10521528
    Abstract: A method for reconstructing at least one output signal associated to a sequential logic circuitry block of a circuit is disclosed. At least one input signal is associated to the sequential logic circuitry block. The method comprises determining a value of the at least one output signal depending on the at least one input signal and determining a transfer function for computing the value of the output signal directly after a timestamp depending on the input signal and/or on the value of the output signal directly before the timestamp. The method further comprises computing the value of the at least one output signal directly after the timestamp as a function value of the transfer function, if a reconstruction condition is fulfilled.
    Type: Grant
    Filed: May 16, 2017
    Date of Patent: December 31, 2019
    Assignee: Synopsys, Inc.
    Inventors: Parijat Biswas, Shyam Datta, Subhrajyoti Chakraborty, Minakshi Chakravorty

  • Signal reconstruction in sequential logic circuitry
    Patent number: 9684746
    Abstract: A method for reconstructing at least one output signal associated to a sequential logic circuitry block of a circuit is disclosed. At least one input signal is associated to the sequential logic circuitry block. The method comprises simulating a value of the at least one output signal depending on the at least one input signal and determining a transfer function for computing the value of the output signal directly after the simulation timestamp depending on the input signal and/or on the value of the output signal directly before the simulation timestamp. The method further comprises computing the value of the at least one output signal directly after the simulation timestamp as a function value of the transfer function, if a reconstruction condition is fulfilled.
