Representation of Algorithms for Schematic Synthesis of Radio Engineering Devices in the Knowledge Base of the Expert System

Creating a new generation of radio engineering devices requires continuous improvement of centers and computer-aided design systems. Moreover, the hardware design itself is currently impossible to imagine without the widespread use of CAD systems at various levels, including end-to-end. To do this, you need to automate the initial design - circuit synthesis. It is proposed to use object-oriented and production expert systems. The generalized model of RTU synthesis is proposed, which is an ordered sequence of necessary actions of the designer, allowing, depending on the specific design task, to achieve the goal. The algorithm for synthesizing the RTU structure has been developed that provides generation and finding a technical solution that satisfies the technical requirements. The proposed basic rules of generation, transformation, and selection of the synthesized structures of the RED. The main design procedures for the initial stages of RED design and the composition of software tools necessary for the effective use of expert knowledge are defined. The basic principles of dialog interaction with the designer in the formation of the expert knowledge base are formulated. The stages, sequence of actions and procedure for presenting information to the expert when working with the subsystem for identifying expert design knowledge are defined.
