Abstract :
SAFEbus is slated to become the first standard backplane bus for commercial avionics. It has been accepted as the draft for ARINC Project Paper 659. SAFEbus is designed to provide communications of all data among the line replaceable modules in the Boeing 777 Airplane Information Management System (AIMS) cabinets. The success of an integrated cabinet hinges on the backplane bus. It is the mechanism responsible for maintaining the space and time partitioning required to ensure that independent functions, which are sharing the cabinet resources, cannot adversely affect each other, even if the designs of one or more of the functions are faulty. A custom protocol is necessary since no existing standard bus was found to provide the fault tolerance or partitioning required for AIMS validation
