Abstract:
|
This paper presents a set of sufficient conditions for the gate-level synthesis of speed-independent circuits when constrained to a given class of gate library. Existing synthesis methodologies are restricted to architectures that use simple AND-gates, and do not exploit the advantages offered by the existence of complex gates. The use of complex gates increases the speed and reduces the area of the circuits. These improvements are achieved because of (1) the elimination of the distributivity, signal persistency and unique minimal state requirements imposed by other techniques; (2) the reduction in the number of internal signals necessary to guarantee the synthesis; and finally (3) the utilization of optimization techniques to reduce the fan-in of the involved gates and the number of required memory elements. |
