This chapter will describe in detail the use of power gating for leakage reduction along with cell-based design automation methods employed by the CoolPowerTM design tool, and is organized as follows. The next section briefly surveys different leakage reduction techniques, providing the motivation for power gating. The subsequent sections describe design issues, CoolPower automation methods including analysis and optimization techniques, and two different power gating application flows as well as results from using those flows. This chapter then concludes with a view to the future and likely new developments in power gating design.
