The power gating technique is useful in reducing standby leakage current, but it increases the gate delay. For a functional unit, its maximum allowable delay limits its smallest standby leakage current its power gating can achieve. In this paper, the authors point out that, in the high-level synthesis of a nonzero clock skew circuit, the resource binding has a large impact on the maximum allowable delays of functional units; as a result, different resource binding solutions have different standby leakage currents.
