A power driven two-level logic optimizer

In this paper we present Boolean techniques for reducing the power consumption in two-level combinational circuits. The two-level logic optimizer performs the logic minimization for low power targeting static PLA, general logic gates and dynamic PLA implementations. We modify Espresso algorithm by adding our heuristics that bias the logic minimization toward lowering the power dissipation. In our heuristics, signal probabilities and transition densities are two important parameters. The experimental results are promising.
