This paper will describe the use of a syntax driver in writing a logic equation compiler (LOGCOM). By such a compiler or processor we mean a program which takes logic equations punched on cards and converts them into a tabular form which subsequently is used by other design automation programs. In the body of the paper it is assumed that the reader… (More)

The evolution of CAD (Computer-Aided Design) in response to the increased requirements of design engineers is discussed, and the effect of increased CAD capability on CAD philosophy is studied. It is noted that without the increases in hardware and software capabilities experienced in the last decade, these increases in capability would not have been… (More)
In the computer-aided design of digital equipment, by the time a wire unit is in the check-out lab, a large amount of information concerning this unit exists in the form of tape files. Since our D.A. System is entered via logic equations, we have a file containing this information, plus files indicating the partitioning of the equations, the placement of… (More)
Many projects have applied the Hatley-Pirbhai real-time structured analysis method to the definition and analysis of system/software requirements. Application of the method results in the generation of a functional requirements model, which includes data/control flow diagrams, plus process and control specifications. Although infrequently applied, the… (More)
