Abstract
The article presents the research of self-timed and synchronous circuits in terms of resilience to soft
errors which can cause disruptions in the control system's operation of complex technical device. The use of
a fail-resilient self-timed code is proposed, which considers the antispacer state as the second spacer state. This
approach increases the self-timed circuit's failure resilience level. In the first approximation, quantitative estimates
show that the self-timed pipeline has a better failure resilience than the synchronous counterparts by 2.0-4.7 times.
The use of modified C-element to implement the pipeline register bit increases this advantage to 2.2-5.4 times. Due
to this, self-timed circuits are the preferred basis of failure resilient control systems implementation for complex
technical equipment.
