Traditionally, David Letterman style, we should really have the top 10 reasons for wasting power in semiconductor design, but here are the five big ones.

Starting with reason #5: Lack of a power gating strategy
Leakage power is a huge proportion of total power and the only way to save leakage power (apart from low leakage cells when… Read More
