In a computer implemented circuit simulator, a method is provided for measuring energy consumption of a circuit under test during a measurement interval. The method comprises a series of computer implemented steps. A supply voltage is applied to the circuit under test. A current flowing through the circuit under test is then measured. A mirror voltage, representative of the value of the current, is generated. A capacitor is charged, with a power parameter voltage equal to the product of the supply voltage and the mirror voltage, during the measurement interval. An accumulated voltage is measured across the capacitor, wherein the accumulated voltage is representative of energy consumed by the circuit under test.
