  • Patent number: 10146895
    Abstract: The present invention discloses a method for simulating a digital circuit comprising: acquiring a gate-level netlist of the digital circuit, the gate-level netlist indicating at least one gate circuit included in the digital circuit and a connection relationship thereof; modifying the netlist, so as to add a timing and power model of each gate circuit, which is used to calculate a time delay generated when a signal inputted to the gate circuit passes through the gate circuit and a power consumed by the gate circuit during its operation; and simulating the digital circuit based on the modified netlist. By adding into the netlist the timing and power model of each gate circuit included in the digital circuit, a power estimation of the digital circuit can be performed while a function verification is performed on the digital circuit, thus function verification is seamlessly combined with the power estimation.
