A Heuristic to Determine Low Leakage Sleep State Vectors for CMOS Combinational Circuits

Input vector control has been used to minimize the leakage power consumption of a circuit in sleep state [1]. In this paper, we present a novel heuristic for determining a low leakage vector to be It can be shown that determining the minimum leakage input vector is an NP-hard problem. Many approaches for determining the minimum leakage vector have been suggested. In [1], the authors presented a formulation for determining the minimum leakage vector using a random search method with a 1Department of EECS University of Michigan, Ann Arbor
