【摘要】：针对胚胎电子细胞阵列在线故障检测设计困难、检测率低、检测率难以准确计算等问题,提出了一种基于双模冗余的在线故障检测方法和一种基于电路等价性验证的故障检测率分析方法。设计了一种适用于查找表型功能单元的新型检测器,并开发了自动化设计程序。针对单固定型故障,将电路转变为待验证电路,再通过故障注入和等价性验证,可以快速精确地计算电路的故障检测率。仿真实验选取16个不同规模的标准电路,分别映射在胚胎电子细胞阵列中,分析了双模冗余后面积、延时变化情况和双模冗余的故障检测率。仿真结果给出了较为详细的面积消耗、电路延时和故障检测率等数据,并验证了本文方法具有很高的故障检测率。
[Abstract]:In view of the difficulties of on-line fault detection of embryonic electronic cell array, the detection rate is low, and the detection rate is difficult to calculate accurately. An on-line fault detection method based on dual mode redundancy and a fault detection rate analysis method based on circuit equivalence verification are proposed. A new type of detector suitable for finding phenotypic functional units is designed. An automatic design program is developed. For a single fixed fault, the circuit is transformed into a circuit to be verified, and then through fault injection and equivalence verification, The fault detection rate of the circuit can be calculated quickly and accurately. Sixteen standard circuits of different sizes are selected in the simulation experiment, which are mapped into the embryonic electronic cell array, and the area after double mode redundancy is analyzed. The simulation results show the detailed data of area consumption, circuit delay and fault detection rate, and verify that the proposed method has a high fault detection rate.
