Benefits of Model Based System Engineering for Avionics Systems
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.
