The interactive-graphic man-computer dialogue in computer-aided circuit design

The crucial role played by the man-computer dialogue in computer-aided circuit design, and particularly within an interactive graphic medium, is demonstrated by reference to a working circuit design facility implemented on a minicomputer. The detailed nature of this facility and the techniques illustrated are related to the circuit design process and the behavioral characteristics of the human designer. Special attention is given to the command dialogue, and to the introduction of flexibility allowing a user to modify the facility to suit his own needs.
