| Abstract: | The introduction of module test and maintenance bus(MTM-Bus) has taken much convenience to the hierarchical boundary scan test technology. This paper introduces the theorem and application of MTM-Bus briefly, presents the architecture and designing of system level boundary scan test system. It also presents the method of designing the M-module controller and S-module controller of MTM-Bus by using FPGA, builds the test system, and gives the software of it. By testing and verification, it shows that the test system is stable, the key technology has general availability,and it can accomplish the fault diagnosis and location properly. |
