Abstract
When the inspection unit corresponding to at least one disabled layer of a multilayer system is unavailable, a fault-eliminating device defines the at least one disabled layer and a target layer as a combined layer. The fault dependency of the target layer is the lowest among the fault dependency of the at least one available layer. The inspection unit of the at least one available layer is active and the fault dependency thereof is higher than the disabled layer. Then, the device makes the inspection unit and the fault symptom corresponding to the target layer correspond to the combined layer, so as to update a list of layers and a fault model. After that, the device determines a source of a fault from the layers according to the list of layers and the fault model, and performs a strategy of fault elimination corresponding to the source, to eliminate the fault.
