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.
