Estimation rapide du couple énergie/délai des circuits asynchrones QDI

This paper proposes a fast estimation method for energy and latency of QDI (quasi delay-insensitive) asynchronous circuits. The energy and latency results can be combined into an Et n metric for allowing comparison between different asynchronous implementations. Furthermore, each implementation can be transformed and new values of energy and latency can be quickly and easily recalculated. In this way, it is possible to determine the sensitivity of an implementation to a given transformation.
