摘要
IEEE1149.4标准(DOT4)为解决数模混合电路的边界扫描测试提供了有效的方法,对于数模混合差分电路的互联测试,一直是数模混合电路中互联测试的重点之一,介绍了一种基于此标准的差分互联电路的测试方法以及差分模拟边界扫描单元的应用,对混合差分电路实现了简单互联和扩展互联的边界扫描测试,从而提高了差分电路互联测试的能力。
IEEE1149. 4 infrastructure has been aimed primarily for the boundary scan test of the mixed - signal circuits. For the differential testing, it is very important in the mixed - signal test. There is a method for testing differential eonneetion circuit and the application of ABM （analog boundary module）, which conform this standard completely. It realizes the boundary scan differential testing for the mixed - signal circuits, so as to enhance the test capability for the differential circuit.
