We present a self-checking detection and diagnosis scheme for transient, delay, and crosstalk faults affecting bus lines of synchronous systems. Faults that are likely to result in the connected logic sampling incorrect bus data are on-line detected. The position of the affected line(s) within the considered bus is identified and properly encoded. The proposed scheme is self-checking with respect to a realistic set of possible internal faults, including node stuck-ats, transistor stuck-ons, transistor stuck-opens, resistive bridgings, transient faults, delays and crosstalks.
