Mechanisms of storage cells errors of SRAM have been determined under the influence of various types of ionizing radiation. The samples were exposed to radiation on electron accelerator (pulse bremsstrahlung), neutron generator (static neutron radiation), and nuclear reactor (pulse gamma and neutron impact). In order to determine the error mechanisms under various radiation exposures, an analysis of cache error sheets (distribution of inverted storage cells) has been applied.

Keywords: single event effects, SRAM, gamma quanta, neutrons, pulse of ionizing radiation.

A procedure of multi-level program injection of errors in Verilog simulator of integrated circuit has been presented, considering its topology and data of SPICE-characteristics of standard cell library, with reference to which it had been designed. Thus, simulation under this methodology is performed at several abstraction levels at once. The presented procedure is the evolution of the methodology, presented by the authors earlier, by adding data registration of SPICE-characterization. The procedure, as before, is fully compatible with the standard route of development of error-tolerant integrated circuits. The procedure has been demonstrated on various by error-tolerance options of implementation of computing unit within the encryption core by AES standard.

Keywords: error injection, injection, Verilog, SystemVerilog, SPICE, single event effects, single event upsets, short-term pulse signals, failure tolerance.

The methodology of testing microcircuits for pulse electrical durability, allowing replacing tests in active electrical mode with tests in passive electrical mode, is offered. In that event, the amplitude Um of influencing single voltage pulses in passive electrical mode may fall within the range 0 ≤ Um ≤ Um (pulse electrical durability).

Keywords: microcircuits, pulse electrical durability, single voltage pulse, active and passive electrical modes of microcircuit tests.

Physical properties of absolute ionization monitor of a proton beam, operating in the real-time mode, have been studied. A monitor detector represents two free-air ionization chambers with transverse electric field against beam route, combined in one module. In chambers signal electrodes have different lengths along the beam. The distances between high-voltage and signal electrodes are proportional to lengths of signal electrodes. The option to vary electrode length allows changing the measured proton flux range promptly.

Keywords: ionization detector, proton flux.
