DEVELOPMENT OF ON-LINE SYSTEM FOR COMPUTER-AIDED DESIGN OF INTEGRAL CIRCUITS. VOLUME II. APPLICATIONS MANUAL.
Abstract
A system of computer programs called CADIC (Computer-Aided Design of Integral Circuits) has been developed to assist in the layout design of Integral circuits. CADIC is a man-machine system that takes full advantage of human judgement, while relieving the man of much routine work. From a description of the circuit schematic, CADIC computes an initial layout, automatically supplying detailed part geometries. The layour is displayed on a cathode-ray tube. Components are then rotated, moved, reshaped, interconnected, etc. by CADIC in response to designer interaction via a light pen and function keyboard. As the layout is manipulated on the CRT, it is automatically checked against solid state design rules. The system responds immediately to the designer's commands, thus eliminating many of the delays associated with the traditional use of computers. Upon completion of the design, CADIC contains the data necessary to completely describe the set of mask patterns used in the various process steps for fabrication. Detailed instructions for the solid-state device designer for use of the CADIC system are given in this volume. Details of the design philosophy and the various features of the system are presented in Volume I of this report. (Author)
