„SmartData: A Data-centric Approach to the Design of Safety-Critical Systems“ Data is at the core of the design of modern Safety-Critical Systems. Data is no longer only sensed and processed in the context of the control loops of such systems. It is also secured, stored, and transmitted for the sake of the decision-making processes required for higher levels of autonomy. The task-centered strategies traditionally used to design critical systems consistently support scheduling analysis and verification of tasks execution times, as long as periods, deadlines and execution time estimates are known, but mostly ignore the flow of data across the various components in the system and often assume that data generation time is constant and can be fully encapsulate in the execution time of tasks. A Data-driven approach to the design of such systems can more promptly accommodate requirements such as data freshness, redundant data sources, operational safety, and AI-readiness. It also facilitates the design of mechanisms to monitor, and eventually override, non-deterministic components such as the neural networks commonly used in autonomous systems. In this talk, we present the SmartData concept, which was conceived at LISHA/UFSC to handle these design issues. The talk addresses aspects of domain decomposition, scheduling, communication, formal property specification and verification, and component overriding. The Autonomous Vehicle being built at UFSC lays a case background for the talk.
