WebEach shift register is called a boundary scan cell. These boundary scan cells allow you to control and observe what happens at each input and output pin. When these cells are connected together, they form a data register chain, called the Boundary Register. Figure 1 A boundary scan device. There are other registers within a boundary-scan device. WebTesting. The boundary scan architecture provides a means to test interconnects (including clusters of logic, memories, etc.) without using physical test probes; this involves the addition of at least one test cell that is connected to each pin of the device and that can selectively override the functionality of that pin. Each test cell may be programmed via …
