摘要

As technology advances, power consumption becomes a big challenge in modern very large-scale integration designs. To resolve this problem, power-gated technology has been widely adopted in circuit designs. Since the turn-on sequence of power switches has a great impact on the rush current, wake-up, and sequence times of a power gating design, this paper proposes a methodology to construct a hybrid routing structure to connect power switches. Our hybrid routing structure can induce less rush current and satisfy timing constraints because a better daisy chain is constructed. To find members of the daisy chain, an integer linear programming algorithm is used to pick up suitable power switches. To determine suitable depth of a daisy chain, we propose a model for a power gating design and induct precise equations to estimate voltage and rush current equations according to the model. All of our experiments are based on industrial designs and measured by vendor tools. The experimental results demonstrate the efficiency and effectiveness of our design methodology.
