JTAG连接器标准、JTAG引脚连接器

Joint Test Action Group(也称为JTAG)是IEEE标准1149.1的常用名。此标准为测试板级互连器定义了一种特殊方法,这种方法也称为边界扫描。简言之,JTAG的建立初衷是测试常见问题,但后来已经成为一种配置设备的方式。JTAG硬件可以解读五个不同信号的信息:TDI(测试数据输入)、TDO(测试数据输出)、TMS(测试模式选择)、TCK(测试时钟)和TRST(测试报告 - 可选)。

边界扫描技术的主要优势是,能够独立于应用逻辑观察设备输入中的数据和控制输出中的数据。简单的测试即可找到各种制造缺陷,例如端子未连接、设备缺失、电路板上的设备不正确或旋转,甚至是设备出现故障或损坏。
