BSCAN 是一种用于测试和验证集成电路的技术。在集成电路中，有许多引脚 （pins）用于与其他器件进行通信和连接。BSCAN 通过在芯片引脚之间添加可控的扫描链 （Scan Chain），使得我们能够在测试和调试时以串行方式访问每个芯片引脚。如下图 -> BSCAN诞生的契机是什么呢？电路板的日益复杂和 surface mount te

因此需要有一个针对更复杂电路(如多核和SOC)可测性设计的通用结构,其中,IEEE 1500[9]标准是这方面的有益尝试。 第二,可复用性:芯片设计中,除了需要考虑可测性设计DFT以外,还需考虑(硅后)可调试性设计(Design For Debug,简称DFD)[10],由于DFT和DFD有很多的共同点,因此,可以考虑将DFT和DFD部分单元进行复用。

甚至一颗小小的PM2.5就可能导致芯片报废,为了能有效的检测出生产中出现的废片,需要用到扫描链测试(scan chain),由此产生了可测性设计即 DFT flow. DFT 第一步是做 scan chain,首先将电路中的普通 DFF 换成 scan DFF: scan DFF 是在原DFF 的输入端增加了一个 MUX,于是多了几个 pin :scan_in,scan_enable...
