Abstract :
Traditionally, RTL power estimation techniques characterize a component for a fixed environment (most importantly load capacitance, activity, and operating frequency). This article presents a solution to problems originating from the ineluctably changing operating conditions such as differing load capacitance due to different applications; different activity and operating frequency. These techniques can be used in design power reduction.
