Abstract
A method comprises estimating power consumption of an electronic circuit. The estimating includes assigning a first gate of the at least one gate into a priority queue based on a levelized result of the electronic circuit for a full circuit calculation and assigning a second gate of the at least one gate into the priority queue which fan-out gate is directly connected to a fan-in gate of a resized gate for an incremental circuit calculation. The estimating includes, for each gate from the priority queue, performing the following operations. Latest and earliest signal arrival times at an output net of the gate are determined by static timing analysis and calculating a glitch window as difference, and a transition metric is calculated for the output net based on the glitch window. The operations include determining an upper bound of signal transitions, and estimating the power consumption based on the upper bound.
