Abstract :
In this paper, an asynchronous TSC 1-out-of-3 (1/3) code error indicator is introduced that memorises erroneous 1/3 code inputs {000, 011, 101, 110, 111} with time duration greater than a discrimination time T. Such an error indicator is used to discriminate transient erroneous 1/3 code inputs from real ones as well as to detect not only faults that cause logical errors but also delay faults (short or long) that alter the circuit delay outside its specified limits (upper or lower bounds) without causing logical errors. To our knowledge, our error indicator is the first TSC 1/3 code error indicator proposed in the open literature
