【Abstract】 With the advent of portable and high density microelectronic devices, the power dissipation of VLSI CMOS circuits is becoming a critical concern in design. The estimation of average power dissipation of a circuit through exhaustive simulation is impractical. The least square method was proposed for estimating the average power dissipation in CMOS circuit. This method is distribution independent in terms of the power of the circuit and unbiased. The experimental results for the ISCAS85 show the faster convergence than that by the Monte Carlo method.更多还原
