作者解决的问题，产生最小的测试集诊断故障的布线互连印刷电路板。假设所有网络都可以并行访问或通过板上的边界扫描链访问。故障模型包括多个固定故障和短路故障。三种不同的诊断机制的三种方法。同时指出，对于非对称错误，自诊断问题与并发错误检测问题是相同的。因此，所考虑的诊断方法类似于并发错误检测中使用的编码方法。通过利用电路板的几何形状进行高效测试，所有诊断方法都可以扩展到结构测试。<<ETX>>
The authors address the problem of generating minimum test sets for diagnosing faults in wiring interconnects on printed circuit boards. It is assumed that all the nets can be accessed in parallel or through a boundary-scan chain on the board. The fault model includes multiple stuck-at and short faults. Three methods for three different diagnosis mechanisms are presented. It is also pointed out that the self-diagnosis problem is the same as the concurrent error detection problem for asymmetric errors. Thus, the diagnostic methods considered are similar to the coding methods used in concurrent error detection. All the diagnostic methods can be extended to structural tests by taking advantage of the geometry of a circuit board to produce an efficient test.<<ETX>>
