Completely self-diagnosable digital systems

Abstract In introducing the concept of ‘complete self-diagnosability’ two basic structural models are described. The models are intended to realize a diagnostic capability that assures the location of faults not only in the main system but also in the auxiliary system which is meant to diagnose the main system, Necessary conditions for the minimum weight of a completely self-diagnosable system which is made up of a large number of modules arc derived.
