Low power oriented circuit optimization consists in selecting the best alternative between gate sizing, buffer insertion and logic structure transformation, for satisfying a delay constraint at minimum area cost. In this paper, we used a closed form model of delay in CMOS structures to define metrics for a deterministic selection of the optimization alternative. The target is delay constraint satisfaction with minimum area cost. We validate the design space exploration method, defining maximum and minimum delay bounds on logical paths. Then we adapt this method to a "constant sensitivity method" allowing us to size a circuit at minimum area under a delay constraint. An optimisation protocol is finally defined to manage the performance constraint/circuit structure trade-off. These methods are implemented in an optimization tool (POPS) and validated by comparing, on a 0.25 μm process, the optimization efficiency obtained on various benchmarks (ISCAS'85) to that resulting from an industrial tool. |
