This paper describes the capabilities of the Graphics-TR programmatically technical complex (PTC) as a tool for teaching university students the general principles of computer-aided design of schematic documentation using the Graphics-TP programmatically technical complex. A brief history of the development of CAD, CAM and PDM systems in our country and abroad is presented. The main disadvantages of using foreign CAD in Russia are given. Attention is focused on electronic design automation (EDA) systems for circuit engineering tasks, which is a subspecies of CAD systems. The article provides a justification for the development of domestic software at the scientific Institute (Computer Graphics Laboratory, part of the division of the V. A. Trapeznikov Institute of management problems of the Russian Academy of Sciences) for solving problems in the field of EDA design. With the help of "Graphics –TR", we consider computer modeling of circuits by automating design work on the example of a practical solution to the problem in the field of circuit engineering and development of printed circuit boards. There are also examples of practical classes on the study of circuitry by students of MTUCI on the course of lectures "Computer modeling of circuits and devices".
