The method of hierarchical macro-modeling as a way to reduce the complexity of the process of analysis of linear electrical equivalent circuit and the quality of the design in CAD
In this paper we propose a method of modeling linear equivalent electrical circuit formed by artificial elektroanalogy based on their two-stage reduction. This method can improve the efficiency of methods of analysis of mathematical models of designed objects at the macro level, presented in the form of linear electrical equivalent circuit, therefore, to improve the quality of design of technical facilities. In the first step of the simulation model of each sub-circuit of the initial scheme formally converted into a macro model that reflects only its expressions like "input-output". In the second stage model consisting of macro models, is converted to the next hierarchical level of the macro model. The mathematical apparatus of macro-modeling is based on the inversion in the analytical form of polynomial regular high degree matrices. The proposed method can significantly reduce the complexity of modeling and multivariate analysis of large equivalent electrical circuits.
