摘要
研究未来航电系统关键协议———SCI(可扩展的一致性接口 )的可靠性建模问题 .从SCI互连的基本模型出发 ,提出了基于任务的系统可靠性分析方法 ,建立了系统的可靠性模型 ,并针对航电系统中SCI的蝶型互连进行了可靠性分析 。
The problem of reliability modeling of Scalable Coherent Interface (SCI) protocol, the candidate standard for the future avionics system, is studied. Based on basic SCI interconnection model, a task-based analysis method of system reliability is proposed. A reliability model of SCI interconnection system is developed. The reliability of butterfly interconnection in SCI avionics system is analyzed. Conclusions show that the method has a directive influence on both task division and topology selection in the phase of avionics system design.
