Abstract

The subject of this paper is a system of programs to aid in the logical design of automata. Figure 1 depicts the experimental system as it presently exists within IBM. There are essentially two internal formats for the system, one called the injective word as shown in Fig. 3. which in essence specifies all the logic blocks in a circuit and how they are linked together. The other is termed a cubical cover (or ON-OFF-ARRAYS) which is a means of describing the behavior of the circuit as if it were a two-level circuit consisting of ANDs followed by ORs (or vice versa). See references 1 and 2 for a more detailed description of these notations.
