Circuit Analysis, Synthesis and Simulation of Radio Devices in Electra CAD

Analysis of the characteristics of the circuit design of radio engineering devices showed the features of the process and the specificity of the sequence and methods of its decisions, especially in the initial design stages. It cannot be reduced to composing equations and finding their solutions; it cannot be reduced only to calculation by formulas too. Therefore, the solution of the problem of circuit design of the radio engineering devices is associated with the need to develop heuristic methods based on expert systems. In addition, it is necessary to programmatically implement a CAD system that can accumulate knowledge in the field of design and act as a co-designer in the process of end-to-end automated design of the radio engineering devices. All this led to the need to implement a CAD Electra, which can be used in circuit design, including educational purposes.
