The optimal wire order for low power CMOS

If adjacent wires are brought into a simple specific order of their switching activities, the effect of power optimal wire spacing can be increased. In this paper we will present this order along with a prove of this observation. For this purpose, it is shown how to derive the new power optimal wire positions by solving a geometric program. Due to their simplicity in implementation, both principles reported substantially differ from previous approaches. We also quantify the power optimization potential for wires based on a representative circuit model, with promising results.     «
