Bridge Fault Model

bridges of four-way or two-way can be classified as either four-way or two-way bridges. By default, static bridge faults will be recorded in four-way bridges, while delay bridge faults will be assigned to two-way bridges. The following sections will elaborate on these two types of bridge models.

Four-Way Bridge Model for Static ATPG

对于网桥静态模型来说,在对抗分析过程中(ATPG)必须生成总共四个静态模式。其中前两个模式将视作:网络A作为攻击者而网络B作为受害者;而后两种情况则将视作:网络B作为攻击者而网络A作为受害者。(如图8-75所示)如果两种网络能够同时进行观察分析,则可能会减少至仅生成两个模式的数量。
