Multi-core and Multi-systems

The complexity of multi-core and multi-system architectures, often built using heterogeneous components like Systems on Chip (SoC), and the mixing of multi-core processors with Open Systems Architecture, provide challenges to test avionics systems, and make it difficult to understand their behavior and define comprehensive testing requirements. Traditional testing methods, designed for single-core systems, are not adequate for verifying the correctness and behavior of multicore systems. Issues like data control coupling, safety critical multicore timing analysis, determinism and the need for extensive coverage testing further complicate the process. What are the latest AMC20-193 guidelines, having replaced CAST-32A? It is important to understand the underlying hardware and software components to effectively test and verify multicore and multisystem avionics systems.
