The large magnitude of supply/ground bounces, which arise from power mode transitions in power gating structures, may cause spurious transitions in a circuit. This can result in wrong values being latched in the circuit registers. We propose a design methodology for limiting the maximum value of the supply/ground currents to a user-specified threshold level while minimizing the wake up (sleep to active mode transition) time. In addition to controlling the sudden discharge of the accumulated charge in the intermediate nodes of the circuit through the sleep transistors during the wake up transition, we can eliminate short circuit current and spurious switching activity during this time. This is, in turn, achieved by reducing the amount of charge that must be removed from the intermediate nodes of the circuit and by turning on different parts of the circuit in a way that causes a uniform distribution of current over the wake up time. Simulation results show that, compared to existing wakeup scheduling methods, the proposed techniques result in a 1-2 orders of magnitude improvement in the product of the maximum ground current and the wake up time.
