Abstract :
This paper presents a self-checking scheme for the on-line testing and diagnosis of intermediate voltage values affecting bus lines because of resistive bridging faults, or different kinds of faults affecting the bus connected units. Our scheme is self-checking with respect to a wide set of possible internal faults, including node stuck-ats, transistors stuck-on, transistors stuck-open, resistive bridgings, crosstalks, delays and transient faults
