Project implementation process data includes classification methods for soft error characteristics and composite fault-tolerant frameworks. Project implementation result data mainly covers models such as soft error classification models, metric models, impact assessment models, fault-tolerant models and feedback test models, which are stored in file format.

Specifically, Dataset 1 mainly introduces the classification model, metric model, impact assessment model, fault-tolerant model and feedback-based reliability test model for soft errors in avionics systems, covering various types of soft errors, measurement methods, impact assessment approaches, fault-tolerant design technologies and reliability test strategies, providing a comprehensive theoretical foundation and technical support for soft error research and protection of avionics systems.

Dataset 2 mainly introduces hardening schemes, including physical hardening schemes and software hardening schemes. The physical hardening schemes involve PCB board-level hardening and reinforcement using various protective materials, such as multi-layer board design, large-area copper pouring, compliance with wiring principles, component layout, and application of protective materials against X-rays, γ-rays and neutron irradiation. The software hardening schemes include triple modular redundancy (TMR), configuration refresh methods (readback refresh and timed refresh) and error detection and correction (EDAC, specifically Hamming code) and other methods, aiming to improve the system's reliability and anti-interference capability through different hardening measures.
