Abstract :
This paper analyzes the problem of timing related common mode failures in redundant systems. The specific case of duplex systems in the presence of delay faults is analyzed by providing a probabilistic characterization of undetectable errors. PDF simulation was used to evaluate the probability of undetectable errors in conventional duplex systems and in duplex systems making use of a simple kind of data diversity.
