Power management is a critical aspect of chip design today. This is especially true for chips designed for portable consumer electronics applications such as cell phones and laptop computers, but even non-portable systems are increasingly optimizing power usage to minimize operation costs and infrastructure requirements. Power management requirements must be considered right from the beginning, and the design and implementation of power management must occur throughout the flow, from early RTL design on through physical implementation. Verification of the power management logic is also essential, to ensure that a device operates correctly even when the
