Abstract :
Power estimation is an important issue in digital VLSI circuit design. The estimation of average power
dissipation of a circuit through exhaustive simulation is impractical due to the large number of primary, inputs
and their combinations. In this paper, two algorithms based on least square estimation are proposed for
determining the average power dissipation in CMOS circuits. Least square estimation converges faster by
attempting to minimize the mean square error value during each iteration. Two approaches namely, the
sequential least square estimation and the recursive least square estimation, are investigated. The proposed
methods are distribution independent in terms of the input samples, unbiased and point estimation based.
Experimental results for the MCNC '91 and the ISCAS '89 bench-mark circuits are presented. While the
sequential least square algorithm performs comparable with the Monte-Carlo method, the recursive least
square method converges up to 12 times faster than the Monte-Carlo technique. 10 Refs.
