/tass/. Scientists of Perm National Research Polytechnic University (PNRPU) have found a way to improve the reliability of electronic devices and products used in space, as well as aviation, military and medical industries. The new method allows to reduce the power consumption of the equipment, and to provide a high level of fault tolerance, the press service of the university told TASS on Monday.
"One of the most common ways to increase the reliability of electronic products is the use of structural redundancy - the introduction of additional backup elements, channels, devices and microchips into the digital system. This approach greatly increases the cost, weight, dimensions and power consumption of the product, but is justified for so-called critical applications: in medical equipment, nuclear power equipment, aviation, space and military equipment," the university reported. "By modeling various redundancy options and analyzing their effectiveness, Perm Polytechnic scientists have proposed a solution that reduces the cost of ensuring reliability while maintaining its high level of fault tolerance."
In particular, to protect the logic elements of the chips from failures and failures that can be caused by high or low temperature, pressure, radiation and other factors, the researchers proposed using redundancy at the transistor level. "The so-called calculation is used: each transistor is replaced by four transistors connected to each other in a special way. This approach makes it possible to ensure reliable operation of the system in case of problems with one of the transistors in each "four", and such cases occur, for example, when a heavy charged particle piercing the spacecraft is exposed to the equipment," the members of the research group explained.
The scientists investigated several options for placing redundant transistor structures in microchips and evaluated the characteristics of their operation using computer modeling. The data obtained are used to identify the most efficient structure of logic elements, which allows to reduce the energy consumption of the microchip as a whole or to reduce the area of the silicon crystal required for its operation.
"The proposed method of finding the optimal structure of the logic element will allow domestic designers to create reliable chips with reduced power consumption for highly reliable equipment used in areas where the cost of error is high, for example, medicine, space, nuclear power and aviation," said Maxim Nikitin, a graduate student, assistant of the Department of Automation and Telemechanics of the Faculty of Electrical Engineering of PNRPU.
The study of Perm scientists has already been published in the journal "Technologies and Components of micro- and Nanoelectronics" for 2022.
About the university
Perm National Research Polytechnic University was founded in 1953. PNRPU is the successor and continuer of the traditions of the Perm Mining Institute and Perm Polytechnic Institute, now it is a multidisciplinary higher education institution providing training and retraining of personnel in technical, technological, natural sciences, economics and management, humanities, social specialties and areas of higher education.
