With the advent of nanometer technologies, circuit performance constraints are becoming ever more stringent. In this context, automated timing analysis and optimization becomes imperative for the design of high-performance circuits that must satisfy a demanding set of constraints. Timing overviews the state of the art in timing analysis and optimization, and is intended to serve as a compendium that can provide an introduction to the uninitiated reader, as a ready reference for a practitioner, or as a source for the accomplished researcher..
