Abstract
Power is the source of the greatest problems facing microprocessor designers. Rapid power variation brings transient errors. High power densities bring high temperatures, harming reliability and increasing leakage power. The wages of power are bulky, short-lived batteries, huge heat sinks, large on-die capacitors, high server electric bills, and unreliable microprocessors. Optimizing power depends on accurate and efficient modeling that spans different disciplines and levels, from device physics, to numerical methods, to microarchitectural design.
