Abstract
Redundancy is one of the main ways to ensure the reliability of critical
equipment, as well as Radiation Hardened by Design, RHBD. They use the Tripling
of digital equipment (majoritation), that is, they use, for example, three
channels of equipment with a choice of "two out of three" using the
so-called Majority Vote Circuit for each bit. In this case, the more Majority
Vote Circuits, the greater the gain in the probability of failure-free
operation. When the entire device (for example, a computer) is tripled, we obtain
a general majoritation. In the case of tripling individual device blocks (for
example, processor, memory, I/O, etc.), we obtain a separate tripling. Further
deepening of the Tripling leads to the so-called Deep Tripling. In principle,
it is possible to triple individual elements. It turns out that the so-called
Quadding at an even lower level-CMOS transistor significantly exceeds the
element tripling, and sometimes it has even less complexity. The article deals
with the features of Tripling and Quadding, the corresponding expressions and
graphs are analyzed.
