Integrated modular avionics architectures combined with the emerging SAE TTEthernet standard provides a strong infrastructure for the deployment of mixed-critical avionic applications having stringent safety, reliability and performance requirements. The integration of such systems is a very complex and challenging engineering task. Therefore, a model-based approach, which endows system engineers with a methodology and the supporting tools to cope with this complexity, is of a paramount importance. In this paper, the authors present an extension for the standard architecture and analysis modeling language AADL to enable modeling integrated multi-critical avionic applications deployed on TTEthernet-based IMA architectures.
