Measuring Active Power Using Pt Px a User Perspective

The authors will review the use of PrimeTime PX (PT PX) to measure active power. With PT PX, one will always get a power value. However, one cannot always rely on this initial power measurement. We will review the conditions under which the generated power numbers are inaccurate and provide strategies to avoid these pitfalls. We will describe a forced gate based flow using VCS and PT PX which enables one to accurately measure power and effectively debug the power measurement results, and describe how this flow can be extended to accurately measure glitch power.
