Abstract :
This paper analyses some of the most common error-detecting codes used in self-checking circuits with respect to the errors induced by crosstalk faults (CFs). The electrical-level behavior of circuits in the presence of CFs has been analyzed by considering these faults as parametric. A logic-level model providing the probability of errors has been abstracted and applied to the case of functional unit outputs (buses). Finally, the probability of detectable and undetectable errors has been evaluated for the parity, two-rail, m-out-of-n, and Berger codes, thus providing some design hint.
