Claim:
A method for performance of a maintenance function of a system under diagnosis, the system under diagnosis comprising a plurality of processing units using a description of the system under diagnosis, the description of the system under diagnosis comprising a description of processing and memory resources of the plurality of processing units, said method comprising: determining sub-systems of processing units based on the description of the system under diagnosis by carrying out a hierarchical decomposition, the system under diagnosis being decomposed into various hierarchical levels into which the plurality of processing units are grouped, a first hierarchical level being lower than a second hierarchical level when the first hierarchical level comprises processing units of the second hierarchical level, and for each sub-system of processing units: determining a behavioral model of the sub-system with a model editor enabling the behavioral model of the sub-system to be generated starting from the description of the system under diagnosis; and allocating a diagnostic method based on processing and memory resources of said sub-system; and transferring a diagnostic function to the sub-system based on the allocated diagnostic method.
