  • Simulation method for use in functional equivalence check
    Patent number: 11170147
    Abstract: A function equivalence check method includes receiving a cell list, receiving an analog constraint of a cell in the cell list, generating the full-coverage input stimuli according to the analog constraint, performing a behavioral-level simulation using the full-coverage input stimuli and according to the behavioral code to generate a behavioral-level simulation result, performing a circuit-level simulation using the full-coverage input stimuli and according to the circuit-level netlist to generate a circuit-level simulation result, and comparing the behavioral-level simulation result and the circuit-level simulation result to generate a comparison report for an analog value auto-comparison.
    Type: Grant
