摘　　要：研究了SCI(可扩展一致性接口 )环型互连的可靠性建模问题 .结合SCI协议及航电系统ICD(接口控制文件 )设计文件 ,提出了基于消息流的源 目的可靠度概念 ,建立SCI环型互连系统的可靠性模型 ,并针对 3种环型拓扑进行了可靠性的建模分析 。The problem of reliability modeling of the SCI (scalable coherent interface) is studied. According to the specification of SCI protocol and the ICD (interface control document) file as well as the reference in the design of avionics system, a message-based source-destination reliability criteria is proposed and the reliability models of the three SCI rings are developed. Conclusions show that the proposed reliability criteria is appropriate to the design of the avionics system where degraded running is a must.
