Abstract

This paper presents a novel checking circuit for Berger codes, with any value of k (also k=2/sup r-1/), which is TSC with respect to a wide set of realistic faults including all possible stuck-ats, transistors stuck-on/stuck-open, as well as several likely to occur resistive bridgings. With respect to the other alternative implementations the proposed checker features the advantage of being inherently more testable, and of requiring lower area overhead.
