  • Publication number: 20130262893
    Abstract: A power estimation apparatus includes a storage unit, a functional model generation unit, and a power estimation unit. The storage unit stores the amount of power per clock transition in a circuit operation that consumes power. The functional model generation unit generates a functional model in which a pin that allows passage of a clock during the circuit operation that consumes power is added. The power estimation unit calculates the amount of power needed during the circuit operation, by operating on a toggle rate of the clock passed through the pin and the amount of power stored in the storage unit.
