Designer-oriented CAD

The philosophy and features of the designer-oriented computer-aided design (CAD) are presented and discussed from both the economic and technical standpoint. Dedication of the CAD system is proposed for efficient design with the minicomputer being the economical choice. Some novel techniques suitable for minicomputers are proposed and a CAD system tailored for designer-oriented operation is described. Based on a 16 k minicomputer, the system generates for each design problem a custom program containing a set of simulated test instruments, thus reproducing the familiar laboratory environment for the designer. A sample problem is given.
