Abstract :
In this paper we present a new library-oriented cell selection approach to minimize power consumption of combinational circuits. Our unified mixed integer-linear-programming (MILP) formulation selects library cells with different gate sizes, supply voltages and threshold voltages simultaneously during technology mapping. Experimental results on benchmarks mapped to an industrial library show that our technique achieves 19% more power saving in less CPU time comparing with other approaches
