This paper analyses the problem of systems' on-line testing with respect to logic errors due to crosstalk, delay and transient faults. In particular we show that logic errors due to crosstalk noise between internal, adjacent lines may not be on-line detectable by conventional concurrent error detection techniques using error detecting codes. Hence, a detector is proposed that allows the on-line detection of such logic errors, and that is self-checking with respect to a wide set of possible internal faults representative of realistic failures, including crosstalk, delay, and transient faults.
