In the former, the state or output of the plant is measured periodically or continuously and information is transmitted over the network only if a certain event condition is met, such as the output deviating from the previously transmitted value beyond a given threshold. Using events in systemverilog requires careful knowledge of simulation execution semantics. Event triggered and time triggered control paradigms. Eventtriggered and timetriggered control paradigms presents a valuable survey about existing architectures for safetycritical applications and discusses the issues that must be considered when moving from a federated to an integrated architecture.
