ABSTRACT
In IC designs leakage power constitutes significant amount power dissipation because CMOS gates are not perfect switches. The leakage power in CMOS gates is dependent on the states of the inputs. This leakage power will get dissipated even when the gates are in idle conditions. Traditionally ECO cells (or) spare cells remain idle in the design and thus contributes to significant state dependent leakage power consumption. In this paper we proposed novel solution to minimize the state dependent leakage power dissipation of the spare cells.
