The methods of design of digital fault-tolerant bipolar integrated circuits to exposure to radiations such as gamma, x-ray and neutron radiation are considered, as well as the impact of the neutron pulse, which af-fect largely on the gain of the transistor. The operating mode of integrated circuits with change in the ini-tial values of voltages, as well as currents of the emitter and of the base is presented. Numerical calcula-tions of the ionization current in the base-collector junction are considered which allow pre-calculate dose rate of gamma, x-ray and neutron radiation.

The technique of radiation-resistant design of integrated circuits in computer-aided design is presented and comparisons with expert data are provided, which are affected by these types of radiations like gam-ma, x-ray and neutron radiation, as well as the impact of the neutron pulse, which affect largely, on the gain of the transistor are examined. Different types of cardinality doses are represented that affect the crystals of integrated circuits based on the real pulse shape of artificial intelligence.

The paper discusses how to create and use models of the original data in an object-oriented subsystem calculate SIM metric supply. The article shows how the modeling of the source information allows to minimize the total computation time, while maintaining ade-quatest of the meet the requirements of the task. The work was carried out with the use of mathematical software and create models, algorithms, data processing, simulation of processes, creation of programs by means of a visual programming technology of formation of symmetrical supply. System-technological approach has been the common methodological basis

The paper considers the model of computing procedures in object-oriented-Noah subsystem of calculation of symmetric supply. The aim is to minimize the total computing time and show how the data is of a quality information product meets the requirements of the task. As a means of solving applied mathematical methods and models, data processing algorithms, modeling tools, processes, programmes, technologies of formation of symmetric supply.

We consider the program block decision-making in the subsystem verification in terms of putting in the problem-oriented CAD calculation symmetric deliver. Calculate and analyze the conditions in which this decision may Bat made for the organization of the technological chain formation of the implementation plan of the specificity-deliver.
