Study on Novel Self-diagnosis at System Level | Chapter 8 | New Visions in Science and Technology Vol. 3

This study proposes a novel technique to self-diagnosis at the system level. The state of the units that are examined by other system units has traditionally been the focus of system self-diagnosis. The proposed method, on the other hand, uses the results of tests performed by a system unit to determine its own state. In many ways, such diagnosis is akin to self-testing because a unit checks its own status, which is a key component of self-testing. Unlike self-testing, the suggested method requires a unit to evaluate itself based on tests done on other system units rather than on itself. Different diagnosis models are studied, each with its own set of testing assignments and faulty assumptions, such as permanent and intermittent faults, as well as hybrid-fault situations. Computer simulation was used to verify the correctness of the diagnosis algorithm for determining the state of the unit. It is commonly assumed that a unit comprises some fault-free subsystem capable of correctly running the diagnosis algorithms for self-testing and self-diagnosis.
