SYSTEM-LEVEL HYBRID FAULT DIAGNOSABILITY WITH GENERAL TEST INVALIDATION
Abstract
On the basis of a self-checking system model with general test invalidation the problem of diagnosability in the case of permanent and intermittent faults known as hybrid fault situation is discussed. Two hybrid fault models have been introduced that take into consideration the behaviour of the faulty tester. On the basis of the relationship that exists between the permanent and hybrid fault models, given the number of all units in a system, the upper bound of the number of diagnosable faulty units is defined without restriction on the test connection assignment.
