Méthodologie de test pour cartes mixtes analogiques-numériques

Abstract : This thesis addresses the issue of mixed-signal board test in maintenance stage. Numerous test methods and test tools have been developed mainly for the test of circuits at design and production stages in hardware test. Surprisingly, one may notice that little interest has been placed into testing during the maintenance stage. However, some systems, like military systems for example, need to be maintained in operational conditions for decades. It is therefore important to ensure that the boards' functionalities of such systems do not deteriorate over time. Should a board become faulty, diagnosis help is then useful to fix it. We propose a functional test methodology which suits the maintenance context. This methodology allows functional modelling for analogue, digital and mixed-signal components in a uniform way and is flexible with regard to the amount of information available on the board. The test data generation process is driven by global test strategies (suitable to preventive maintenance) or local test strategies (more suitable to corrective maintenance). Test engineers' expertise and industrial practices are essential and are taken into account by the methodology in the form of test models and test tactics which specify the test data generation process. The proposed methodology is implemented into a prototype tool by using constraint logic programming and its application to several examples of mixed-signal boards is discussed.
