Maximum current estimation in CMOS circuits

Abstract

The authors propose pattern-independent, linear-time algorithms that provide tight upper bounds on maximum envelope current (MEC) waveforms. The proposed approach represents a trade-off between execution speed and tightness of these bounds. The MEC waveform is a point-wise maximum on all the possible waveforms that the circuit can draw. Experimental results on several benchmark circuits are provided to establish the usefulness of this approach.<>
