Embraer began development of an ARINC 661-compliant cockpit display system with Esterel Technologies SCADE Solutions for ARINC 661 Applications. Over the past two years, Embraer has been able to build a fully-functional ARINC 661 demonstrator that includes all components necessary for CDS deployment under the ARINC 661 standard. The ARINC 661 demonstrator includes a fully-compliant ARINC 661 server based originally on Esterel Technologies SCADE 661 Server Creator using an automatic server generator. Embraer had successfully integrated a custom ARINC 661-4, widgets library, with Esterel Technologies widget library, designed with SCADE as the base. Embraer has also developed and integrated User Applications running on a IMA hardware system and communicating with the server using UDP over AFDX within a flight simulator system. This paper discuss the process followed by Embraer for development of the ARINC 661 demonstrator.

The increasing complexity of distributed embedded systems, as found today in airplanes or cars, becomes more and more a critical cost-factor for their development. Model-based approaches have recently demonstrated their potential for both improving and accelerating (software) development processes. Therefore, in the project DECOS1, which aims at improving system architectures and development of distributed safety-critical embedded systems, an integrated, model-driven tool-chain is established, accompanying the system development process from design to deployment. This paper gives an overview of this tool-chain and outlines important design decisions and features.
