Translation of a DDL Digital System Specification to Boolean Equations
J.R. Duley, Donald L. Dietmeyer · IEEE Transactions on Computers · 1969
A digital system design language, DDL, has been described and shown to provide a concise yet precise means of specifying the organization and operation of digital systems, regardless of timing mode or hardware types, at various levels of detail [2]. This paper defines a series of tasks that transform any DDL document to Boolean and next-state equations from which a system may be implemented. Each task of the transformation produces another DDL description of a system which uses fewer features of the language.
