• In the design of nonzero clock skew circuits, an increase of the path delay may improve circuit speed and reduce leakage power. However, the impact of increasing path delay on the trade-off between circuit speed and leakage power has not been well studied. In this paper, we propose a two-step approach for leakage-power-aware clock period minimization. Compared with previous works, our approach has the following two significant contributions. First, our approach is the first leakage-power-aware clock skew scheduling that can guarantee working with the lower bound of the clock period. Second, our approach is also the first work that demonstrates the problem of minimizing the number of extra buffers is a polynomial-time problem. Benchmark data show that our approach achieves the best results in terms of the clock period and the leakage power.
