Abstract

Many techniques are used to control the speed of digital designs at architecture level [1] or to stop the clock at gate level, mainly to save power [2]. Some high speed circuits speed up the clock on portions of the design which were not critical otherwise [3]. Asynchronous designs are fine grain speed adaptive, but this solution is not easy to use [4].This article presents an efficient and easy to use technique to increase performance of synthesized digital circuits with low level adaptive speed – i.e. at gate level.
