Monolithic fault detection methods have low accuracy for comprehensive faults detection, because they can only detect specific type of faults. Therefore, it is necessary to study the combination of fault detection methods to improve the detection accuracy. In this paper, based on the fault propagation on component-based aerospace embedded software architecture, we analyze occur reasons, manifestations and effects of instruction-, component- and system-level faults whose root cause is single event upset (SEU) which is the main reason of aerospace embedded software, and propose a hierarchical fault model to specify characteristics of the three levels faults. And based on the hierarchical fault model, a hierarchical detection method is proposed to combine the three levels monolithic fault detection methods. The experimental results show that the hierarchical fault detection method has higher fault detection accuracy than the monolithic fault detection methods for comprehensive faults detection.
