| Abstract: | IEEE1149. 4 standard and mixed-signal test bus were introduced firstly. Then according to the test structure defined in this standard, test methods on mixed-signal circuit were researched, and a boundary-scan controller and demo circuit PCB were designed. Finally, experimental results indicate that the boundary-scan controller is feasible to the test of mixed-signal circuits, and greatly improves observability and controllability of mixed-signal PCB. |
