5.5 Summary
First an overview of high-level system design was given to locate where and why power estimators come into play. The essence is that power estimators provide a criterion, minimal power consumption, that has to be optimised when comparing different architectural alternatives during system design. Next, a definition was given for an analog power estimator and requirements for a good estimator were discussed. The two main qualities are absolute accuracy and tracking accuracy. Then, two different approaches were presented and compared for the construction of power estimator functions: bottom-up and top-down. Next some theoretical estimator examples were discussed and their usefulness and shortcomings depicted. Finally, a few examples of practical power estimators were given, illustrating that in practice some kind of meet-in-the-middle strategy has to be used to generate good power estimates. The level at which topology-specific information has to be used varies from one analog circuit type to another, but inversely affects the generic properties of the estimator.
