A DESIGN METHOD OF ASYNCHRONOUS SEQUENTIAL CIRCUITS BASED ON FLOW DIAGRAM

Abstract

A systematic, asynchronous design method based on a flow diagram is shown. The realization utilizes a so-called phase-register coded 1 out of n. A phase consists of so-called phase- register cells, which are elementary asynchronous networks including edge-sensitive integrated circuit flip-flops. The circuits developed by the proposed method are free of critical races and essential hazard faults.
