An Integrated Approach to Model Based Engineering with SysML, AADL and FACE
Multiple model-based engineering (MBE) frameworks have emerged to cover the many requirements for the engineering of avionics systems: from early requirement capture to the final system and embedded software generation, through refinement and V&V activities. In this paper, we consider the SysML, AADL and FACE standards. They are promoted by different standardization bodies, with different objectives. We note they are often seen as competitive, while we argue it is the opposite: there is a potential for a synergistic coupling. To date, no complete open evaluation on the feasibility of such capability has been done. SysML covers early systems engineering activities: stakeholder needs elicitation, system requirements analysis, functional breakdown and architecture definition. AADL can then be leveraged to refine a more precise architecture of the embedded system under consideration, meeting specific architectural styles such as ARINC653 and perform detailed timing analysis.
