Dual-vdd has been proposed to optimize the power of circuits without violating the performance. In this paper, different from traditional methods which focus on making full use of slacks of non-critical gates, an efficient min-cut based voltage assignment algorithm concentrating on critical gates is proposed. And then this algorithm is integrated into a searching engine to auto-select rational voltages for dual-vdd system. Experimental results show that our search engine can always achieve good pair of dual-vdd, and our min-cut based algorithm outperformed previous works for voltage assignment both on power consumption and runtime.
