摘要： An improved method and system for diagnosing faults of a system under test is provided. One or more candidate diagnoses potentially responsible for observed testing failures are generated. Each candidate diagnosis is then assigned a weight based in part on any of a number of factors not previously considered in the weighting process, thus making the weighting process more accurate. In one case, the weight of a diagnosis may be based on the combined consistent utilization of the candidate diagnosis across all failing system tests. Alternately, or in addition, that weight may be based on the combined utilization of the diagnosis among all passing system tests. Other potential factors may also be used.

摘要： Method for diagnosing faults in a system under test (SUT) are provided. A representative method includes identifying at least some portions of the data transmission paths of the SUT capable of introducing errors in data transfer; providing constraints defining relationships of at least some of the portions of the data transmission paths; and diagnosing the SUT with respect to the constraints. Systems, computer-readable media and other methods also are provided.

摘要： An automated analysis system that identifies detectability problems, diagnosability problems, and possible ways to change rank order of diagnoses in a diagnostic system and makes the problems and possible improvements visible to test programmers to aid in test improvement. Components that have no coverage and components that have inadequate coverage (according to a heuristic criteria) are identified as potential detectability problems. Components that are exercised by identical operations in all tests are identified as diagnosability problems. If an incorrect diagnosis is made, the automated analysis system identifies failing tests that have no coverage of any component in the true failure cause. In addition, if an incorrect diagnosis is made, the automated analysis system identifies ways of changing the rank order of diagnoses, including coverages that can be reduced and identification of operation violations that can be eliminated or deliberately added. If no historical data are available, a "diagnosability index" may be computed by randomly sampling from the set of possible failure syndromes and observing the frequencies with which ties occur among the weights of the top-ranked candidate diagnoses. After historical data becomes available, a diagnosability index may be computed from the frequency with which two candidate diagnoses are assigned identical weights by the model-based diagnostic system over a set of representative failures.
