Abstract :
A comparison with synchronous circuits suggests four opportunities for the application of asynchronous circuits: high performance, low power; improved noise and electromagnetic compatibility (EMC) properties, and a natural match with heterogeneous system timing. In this overview paper each opportunity is reviewed in some detail, illustrated by examples, compared with synchronous alternatives, and accompanied by numerous pointers to the literature. Conditions for applying asynchronous circuit technology, such as the existence and availability of computer-aided design (CAD) tools, circuit libraries, and effective test approaches, are discussed briefly. Asynchronous circuits do offer advantages for many applications, and their design methods and tools are now starting to become mature
