Syndrome-based functional delay fault location in linear digital data-flow graphs

Abstract

A novel approach to fault location in linear digital data flow graphs is presented. The fault location scheme is simple and depends on the linearity property of these data flow graphs. Identification and replacement of the failed component allows operation of the circuit at the desired clock speed. It is shown how timing problems identified during speed testing of a class of circuits widely used in digital signal processing and control can be isolated to individual or sets of circuit components.<>
