Digital System Design Automation—A Method for Designing a Digital System as a Sequential Network System

Abstract—This paper deals with computer-aided design of digital systems and presents a formal method for designing a digital system via state tables. The steps of the design method can be summarized as follows: a) a system is described by a set of microprograms written in a "transfer language," b) the set of microprograms is translated into a set of flow tables by an algorithm, and c) the flow tables are converted into logical diagrams by synthesis procedures. The purpose of step a) is to aid the designer in describing the system; the result of step b) makes it possible to reduce the logical complexity of the system by using systematic techniques of the sequential network theory; and the result of step c) is a system of interconnected sequential networks, operating simultaneously which may include iterative asynchronous networks.
