Abstract :
This paper deals with diagnosis and design for diagnosability at the system level. In particular, diagnosis and design for diagnosability of high-end Internet routers in manufacturing test and design validation are considered. A packet flow model is used for diagnosis down to the replaceable unit level. The diagnosis method operates correctly when there are multiple or intermittent faults. A diagnosability criterion is proposed and a method for assessing diagnosability of various designs given. The paper concludes with a description of empirical results from an industrial application of the diagnosis method
