    • Methods, apparatus, and systems for performing fault diagnosis are disclosed herein. In certain disclosed embodiments, methods for diagnosing faults from compressed test responses are provided. For example, in one exemplary embodiment, a circuit description of an at least partially scan-based circuit-under-test and a compactor for compacting test responses captured in the circuit-under-test is received. A transformation function performed by the compactor to the test responses captured in the circuit-under-test is determined. A diagnostic procedure for evaluating uncompressed test responses is modified into a modified diagnostic procedure that incorporates the transformation function therein. Computer-readable media comprising computer-executable instructions for causing a computer to perform any of the disclosed methods are also provided. Likewise, computer­readable media comprising lists of fault candidates identified by any of the disclosed methods or circuit descriptions created or modified by the disclosed methods are provided.
    • 本文公开了用于执行故障诊断的方法,装置和系统。 在某些公开的实施例中,提供了用于从压缩测试响应诊断故障的方法。 例如,在一个示例性实施例中,接收至少部分基于扫描的测试电路和压实器的电路描述,用于压缩在待测电路中捕获的测试响应。 确定由压实机对被测电路中捕获的测试响应执行的变换功能。 用于评估未压缩测试响应的诊断程序被修改为并入其中的变换功能的修改的诊断过程。 还提供了包括用于使计算机执行任何所公开的方法的计算机可执行指令的计算机可读介质。 同样地,提供了包括通过由公开的方法创建或修改的任何公开的方法或电路描述所识别的故障候选列表的计算机可读介质。
