Abstract:
1. A method for diagnosing functional faults of an assembly of electronic systems, the systems being composed of components that produce and consume data, at least one of the data configured to assume a predetermined particular value following development of a functional fault of at least one of the components of the assembly, the method comprising: i) classifying, during a phase of design of architecture of the assembly of systems, the particular values according to associated types of faults, and the classification being recorded in a computer memory; ii) connecting, during a diagnostic phase, a diagnostic tool to the assembly of electronic systems, the tool having access to the classification; iii) suppressing the particular values corresponding to types of faults of components predefined in the classification as particularly reliable; iv) selecting data that have assumed a particular value; v) automatically calculating, for each datum selected in the selecting, a group of data configured to be responsible for the particular values assumed by the datum; vi) automatically establishing a list of the data contained in an intersection of the groups of data; and vii) recording the particular values and their propagation on a memory for a tool provided for diagnosis of the assembly of electronic systems.
