MacCAD (Macintosh Computer Aided Design), Computer Aided Design Tool for System Analysis

摘要

MacCAD, a computer aided design program, was developed as an analysis tool of continuous, linear control systems for the graduate level Controls or Electrical Engineering student. A variety of programs are presently available for the IBM-PC and the IBM Mainframe. MacCAD is written in Pascal and operates on the Apple Macintosh. It was developed in order to meet the need for a powerful yet simple to use program with high quality graphics and multiple window capabilities. It offers a highly flexible block manipulator capable of handling virtually unlimited blocks and loops, along with the standard analysis tools, Bode, Nyguist, Root Locus and Time response plots. Mouse and menu driven, it offers user defined plotting and calculation parameters which include multiple plot overlapping and linear or logarithmic plot point intervals.
