Self-checking detection and diagnosis of transient, delay, and crosstalk faults affecting bus lines

We present a self-checking detection and diagnosis scheme for transient, de lay, and crosstalk faults affecting bus lines of synchronous systems. Fault s that are likely to result in the connected logic sampling incorrect bus d ata are on-line detected. The position of the affected line(s) within the c onsidered bus is identified and properly encoded. The proposed scheme is se lf-checking with respect to a realistic set of possible internal faults, in cluding node stuck-ats, transistor stuck-ons, transistor stuck-opens, resis tive bridgings, transient faults, delays and crosstalks.
