| Summary |
"Compared to the problem of combinational network (CN) diagnosis, that of sequential network (SN) diagnosis has been an extremely difficult one. Present techniques of SN diagnosis are difficult to apply, and generally lead to lengthy test schedules or additional logic. This paper presents a new approach to the SN diagnostic problem which results in a substantially simpler technique than those found in the literature. The approach is to modify the SN so that it can be diagnosed from a combinatoric point of view. This is accomplished by the addition of outputs for testing purposes to certain lines in the circuit--no additional l logic is required. The applicability of the technique is dependent on the density of stable states associated with the circuit, but attempts at finding a practical flow table whose circuit is undiagnosable by the method have been unsuccessful. Although tests sequences were not the major concern of the investigation, the approach has resulted in almost minimal test sequences"--Abstract, leaf 2. |
