| Abstract: | With the increase of number of components and system complexity,great challenges for test and diagnosis were brought out.Basichardware and softwaremeasures for easiertest and diagnosis in the development of multiprocessor systems were discussed.A multi-level debugnetworkbased-on boundary scan was presented.A method for constructing,-diagnosable system by the Cartesian product and an idea of optimizing diagnosis algorithm by preprocessing were given. |
