| Abstract(in English) | Power gating technology has been widely used in VLSI designs for leakage power reduction by cutting off power supply to idle blocks. In previous work, a controlling value based method has been proposed. However, power saving capability suffers drastically from the depth constraint, which is inserted to avoid performance degradation. For increasing power savings, this paper introduces a controllability propagation property based on connection of the logic elements to enable a signal to control multiple clusters. Experimental results show that expected number of sleep gates can witness an 8% increase compared with the previous algorithm. |
