Many cyber-physical systems are hierarchical distributed control systems whose components operate with different rates, and that should behave in a virtually synchronous way. Designing such systems is hard due to asynchrony, skews of the local clocks, and network delays; furthermore, their model checking is typically unfeasible due to state space explosion. Multirate PALS reduces the problem of designing and verifying virtually synchronous multirate systems to the much simpler tasks of specifying and verifying their underlying synchronous design. To make the Multirate PALS design and verification methodology available within an industrial modeling environment, we define in this paper the modeling language Multirate Synchronous AADL, which can be used to specify multirate synchronous designs using the AADL modeling standard. We then define the formal semantics of Multirate Synchronous AADL in Real-Time Maude, and integrate Real-Time Maude verification into the OSATE tool environment for AADL. Finally, we show how an algorithm for smoothly turning an airplane can be modeled and analyzed using Multirate Synchronous AADL.
