英文摘要：

To resolve oversize time consuming problem in simulation based maximum power analysis, Bayesian power model based on slice analysis is proposed. This model selects the input vector set which may generate maximum power and performs accurate power estimation for the compact sequence. The relationship between signal switch density and maximum power generation is analyzed, and then an input vector generation platform with switching density self-adaptation computing and Bayesian vector compression is proposed. The experimental results indicate that, Bayesian vector compression method results in 1005 times average estimation time speed-ups, and the average maximum-power error is 2.40%. When using vector generation method based on selfadaptation computation and Bayesian vector compression, the maximum power bottom limit can be increased with 1.99%, and average speed-ups reaches 163 times.
