A Model-Based Approach for Early and Continuous Validation of Avionics Platforms up to Virtual Products and Hybrid Platforms

The trend of today’s aviation shows a steadily increasing complexity of avionics systems and related functions. Emerging technologies, such as multi-core avionics, mixed-criticality systems on shared resources, and the adoption of artificial intelligence (AI) in the field of avionics, will accelerate this growth by introducing additional synergies and new constraints. However, this trend makes the complex and non-automated development process of avionics platforms more time-consuming and error-prone. To keep the increasing complexity within reasonable limits and to avoid major design iterations, new methods are needed to continuously validate the design and implementation choices. In this paper, we present a model-based concept for early and continuous validation of avionics platforms under development through all their phases – design, implementation, testing and ultimately, integration.
