The paper considers issues of using information technologies for solving problems of certification and licensing of the enterprises of electronic industry, conducting advanced research and analysis of sales. The structure of the database and identify the steps of adding information.

Developed problem-oriented software software for calculation of parameters of reliability of complex of blocks of software and hardware complexes. A method is proposed for implementation of the software on a walking route design of technical systems.

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.

In article process of impact of space ionization radiation on products of electronic component base is considered, the structure of an algorithm of calculation of firmness of CMOS VLSI at influence of factors of space is described.

Is considered a functional diagram of the algorithm of modeling and creation of failure tolerance scratch pad memory VLSI.
