It was proposed to apply the methods of testing and diagnosis of the nonuniform digital systems to the components of digital systems structured as symmetrical bipartite graphs. To use these methods, the connected heterogeneous devices of the analyzed system were united into identically composed subsystems. A multiagent approach to system diagnosis of the digital systems under study was developed. The interrelations between the agents exercising different functions were established. An example of the multiagent organization of diagnosis of the components of a digital system consisting of seven processors and seven memory units was presented.
