This paper details the way a realistic complex avionics system can be designed in an efficient way using a Model Based System Engineering tool, involving several hundreds of data and ARINC 429 and ARINC 664-P7 messages. The SCADE System Avionics Package comes with the following answers: - User friendly and fully customizable interface thanks to the support of Domain Specific Languages - Clean separation of the Functional, Software and Hardware layers, all relations maintained in a consistent way - Templates for immediate use of standard avionics protocols (ARINC 429, ARINC 664-P7, CAN provided) - Automated generation of all ICDs through powerful “hierarchical tables” that gather information from the model These means are built on top original features that are detailed in this paper; the design of an aircraft Braking System with a COM-MON architecture, 9 sub-systems, 12 partitions, 4 CPU, 2 Switch Cabinet, Dual A/B ARINC 664-P7 network, 14 Virtual Links (VL) that is first presented has demonstrated the efficiency of the tool support.
