  • Circuit testing system
    Patent number: 5381417
    Abstract: The present invention relates to the field of circuit assembly testing systems and provides improved systems and methods for debugging circuit test systems and diagnosing faults in circuit assemblies. An expert system derives possible root causes of test failures, predicts test results based on these possible root causes and uses factual observations to refute inconsistent hypothetical root causes. Tests useful in refuting inconsistent hypothetical root causes are devised and run automatically by the system.
