摘要

Aiming at the topic of test point selection for analog circuitry, the integer-encoding fault dictionary has been studied. Hie test pointselection based on information entropy algorithm is analyzed, and the entropy algorithm is optimized with Rollout algorithm to setup a new testpoint selection algorithm. The detail calculating procedures and effects of the new algorithm are given. The experimental result indicates that theresult of new algorithm is better than information entropy algorithm, and its superiority is more notable when the fault dictionary becomes morecomplex.%针对模拟电路的测点选择问题,对整数编码故障字典进行了研究.分析了基于信息熵算法的测点选择算法,并采用Rollout算法对信息熵算法进行优化,建立了一种新的测点选择算法,给出了新算法的详细计算过程和计算效果.试验结果表明,新算法的计算效果优于信息熵算法,且随着故障字典复杂度的增加,优势更加明显.
