USING AUTOCAD DYNAMIC BLOCKS TO AUTOMATE THE DESIGN OF DIGITAL COMPUTER CIRCUIT DIAGRAMS

Abstract

The article discusses the use and adaptation of CAD (AutoCAD) for solving educational and professionally oriented tasks, in particular, automation of the process of developing and designing schematic diagrams of digital computing equipment in accordance with the requirements of current standards. Computer-aided design makes it easier to create a schematic, edit it, and compile a list of elements. This approach leads to a reduction in design time and an increase in the efficiency of the designer's work.

The article analyses the features and feasibility of using the dynamic blocks apparatus for specific design tasks, automating compliance with norms and standards for design documentation. 

The main part of the article describes the commands for creating, editing and managing blocks. The explanations concern the basics of creating blocks, the meaning of block definitions and occurrences, the differences between static simple blocks, blocks with attributes and dynamic blocks, and the commands for creating and editing them in the block editor. Attention is paid to the management, editing of the type and content of block attributes as data sources for drawing up specifications.  Both static and dynamic blocks are considered and the optimal purposes of their use are outlined.  The difference between static and dynamic blocks as the most powerful and versatile of the considered automation tools is revealed. The principle of organising the universal use of the control centre, creating libraries of blocks and tool palettes is explained. 

The use of blocks, especially dynamic ones with attributes, provides more opportunities for design automation through the creation of specialized libraries of typical elements, including a library of conventional letter-graphic symbols for microcircuits for forming schematic diagrams of digital computing equipment with a list of elements..
