Abstract:
This paper presents a technique to embed diagnosis functions in model-based design of embedded systems, allowing designers to do this at early design stages, before separation of hardware and software (HW/SW) implementations and derivation of several variations. First, we develop some simple monitoring functions suitable for both HW/SW based on JTAG (Joint Test Action Group). Then, in order to identify faulty components in a complex embedded systems where a fault in a component can affect others, we employ a method proposed by Kutsuna et al., which is based on ``model-based diagnosis'' studied in the field of Artificial Intelligence. This paper uses MATLAB/Simulink as a modeling framework, and employs aspect-oriented approach for diagnosis description to promote reuse of diagnosis function models. This method enables to locate a fault source even if the fault propagates multiple modules.
