OR control point的工作原理为:先将Scan_en信号置为1,通过Scan chain向F1024配值为1。当需要控制Y的值时,可以将test_point_en信号置1,这样就可以将最右侧或门的一个输入端口控制为1,便可以将输出控制为1。 AND control point的工作原理与OR control point类似,只是电路结构稍有不同,在此不作过多赘述。 Obser...
AND控制点类似，其原理与OR控制点相近，但具体电路结构略有不同，具体实现细节在此不再详述。观察点的插入遵循类似流程，以四输入与门输入端A0无法观测为例。在A0插入观察点后，电路调整，右侧SFF连接至扫描链。通过设置test_point_en信号至1，将A0值通过与门传递至D端的F0001，再将Scan_en信号置0，...

Test point insertion (TPI) is a widely used technique for testability enhancement, especially for logic built-in self-test (LBIST) due to its relatively low fault coverage. In this paper, we propose a novel TPI approach based on deep reinforcement learning (DRL), named DeepTPI. Unlike ...

SLSC plug-in modules can operate in the chassis in three different modes: stand alone, pass through, or cascaded. Cascaded mode can be used to cascade the signal path through multiple SLSC modules and implement functionality like signal fault insertion. You can choose from a variety of third...
