Computer-Aided Design for Built-In-Test (CADBIT)-Technical Issues. Volume 1.

摘要

CAD-BIT is a development program to specify the implementation of an automated procedure to integrate Built-In-Test into the design of Printed Circuit Boards (PCBs) on Computer-Aided Design workstations. When fully developed, the CAD-BIT software will be capable of operating on generic workstations meeting various standards. These standards include those for operating system (UNIX), programming language (C), and graphical data interchange Initial Graphics Exchange Specification. The program's purpose was to develop the design of the automated procedure, the associated BIT data base, and a software specification for the CAD-BIT module ready for encoding. CAD workstations and BIT techniques and their applications were also surveyed to determine standards required for the CAD-BIT module implementation and to establish requirements for and define the structure of the BIT data base. Volume I is a general CAD-BIT description and provides useful information for any type of involvement with CAD-BIT. It includes a detailed description of the automated procedure. The description contains text, flow diagram of the procedure operations and its data, sets of menu sequences showing menu options, selections, and resulting operations. Algorithms and formulas are included. The CAD-BIT Data Base and its files are described. (edc)
