Automated generation of certification relevant documentation for a distributed avionics platform approach

The development of distributed and fault tolerant avionics systems from the first drafts to the finalization of the certification process is complex, resource intensive (financial and man power) and involves high risks. Therefore, implementations like fly-by-wire systems are usually limited to the FAR25 (CS25) domain. Previous research at the Institute of Aircraft Systems at University of Stuttgart was focused on the development of an avionics platform and a tool suite for a cost-efficient development process for class 23 and class 25 aircraft. Now, the aim is to extend the platform idea towards certification. In doing so, the generation of the specification documentation and testing activities shall be automated while avoiding tool qualification where feasible. This paper presents an approach for the documentation generation and provides an outline to interface with the testing activities.
