The task is to sharply reduce the complexity of analysis, multivariate analysis and parametric optimization of linear and linearized equivalent electrical circuits. The source of such schemes are not only linear electronic circuits, but also circuits formed on the basis of artificial electrical analogies. They can be formed on the basis of finite element methods and finite difference methods used in solving partial differential equations. The reduction in the complexity of computations is carried out by formal methods of transforming the model into a macromodel, which reflects only the input - output type relations of the original model. The e ssence of the work lies in the formal transformation of the model of a linear or linearized equivalent electrical circuit, formed using artificial electrical analogies methods, into a macromodel, according to which the same output characteristics can be calculated with the same accuracy but with increased speed by several orders of magnitude. Algorithms for such transformations are given. Using a macromodel, one can calculate static characteristics, frequency characteristics, zeros and poles of system functions, dynamic characteristics, eigenvalues, and vectors of a macromodel matrix, which make it possible to determine the stability and stability margin of the original circuit using the first А.М. Lyapunov method, its resonant eigenfrequencies and the duration of the transition process, as well as partial derivatives of the above characteristics for a small number of variable circuit parameters to replace the optimization of the circuit with the methods of the 1st order with its optimization by the macro model. In addition, macromodels can be used to create a new element, constructional, and technological base for design. Macromodel can serve as an element of a model of a higher hierarchical level. Block hierarchical process of macromodelling is possible.

The article examines the creation of program to assess the performance durability of radio-signals processing devices. This type devices are widely used in various communication systems and performance durability of these devices have a significant impact on performance durability communication systems. In the currently accepted methods of assessment of the durability indicators of device can be performing calculations in two stages (approximate and refined calculation). This is when a large number of elements significantly increases the complexity associated, primarily, with the search data on the durability characteristics. Therefore, given in the methods the model used for the conversion of durability indicators of the maximum allowed modes and conditions of the use of elements (approximate calculation) to operating modes (refined calculation), is quite simple. However, the use of such models although not strongly influences the complexity of the calculations, but may lead to less accurate estimates of durability indicators. This error will be greater than the maximum allowed modes and the conditions of application of elements differ from operating modes. However, modification of models aimed at improving the accuracy of the calculations that will lead not only to increased complexity of the calculations, but also requirements for the qualification of specialists and, consequently, to the need to create appropriate software and databases. In addition, the need to create such software due to the lack of commercial software tools for the calculation of reliability of domestic and foreign manufacturers of modules of calculation of durability. When creating the calculation program of durability indicators of the radio-signals processing devices were the main requirements, the scheme of information exchange with CAD-systems and specialized CAE-systems, to determine the composition of software modules and the functioning algorithm of the program and designed the model database according to the durability characteristics of elements. This research carried out in 2015 was supported by "The National Research University "Higher School of Economics" Academic Fund Program" grant (No. 15-05-0029).
