A new test quality evaluation method based on output violation probability to reduce errors induced by hazards is presented. The concept of arrival time window is introduced and the concept of output violation probability is defined to accurately reflecting the pattern capability on SDD detection, which eliminates the errors of probability calculation caused by ignoring hazard.Experimental results show that the proposed evaluation method brings no extra nm time overhead, and the selected patterns by this method can achieve higher test quality for SDD detection compared to the previous method based on ouput-deviation.%针对冒险引起的测试质量评估误差,本文提出了一种基于输出违例概率的测试质量评估方法.定义了到达时间窗口和输出违例概率的概念,使用输出违例概率来反映测试向量的小时延缺陷检测能力,有效地避免了忽略冒险引起的计算误差,从而准确的评估了向量对小时延缺陷的检测质量.实验结果表明,相对于基于输出偏移的国际同类方法,本文的评估方法不增加额外的时间开销;在其指导下筛选出来的向量具有更高的测试质量.
