Abstract: The temporal correctness has always been a hotspot and difficult problem in the field of space embedded software. With the theory of timed automata, the interrupt management of a certain onboard operating system and the environment interacting with it are modeled respectively to describe the whole interrupt management process. By using the modelchecking tool Uppaal, the performances of interrupt management are verified, including the reachability, the safety, the liveness and the correctness of service behavior.

Key words: interrupt management, timed automata, formal verification, modeling
