Building Safety Critical Systems

This lecture discusses the importance of integrating efficiency considerations into the design process of safety critical systems, focusing on correctness and efficiency. It explores the challenges faced in achieving both correctness and efficiency, the role of certification authorities, the development of new design techniques, and the move towards integrated computing environments. The lecture delves into topics such as real-time computing, model-based design techniques, synchronous reactive programming, worst case execution time analysis, mixed criticality scheduling, and cyclic executives. It also addresses the social aspect of achieving certification, the need for graceful degradation in systems, and the complexities of certification processes. The instructor emphasizes the need to balance correctness, efficiency, and development costs in building safety critical systems.
