HybridSynchAADL: Modeling and Formal Analysis of Virtually Synchronous CPSs in AADL

We present the HybridSynchAADL modeling language and formal analysis tool for virtually synchronous cyber-physical systems with complex control programs, continuous behaviors, and bounded clock skews, network delays, and execution times. We leverage the Hybrid PALS equivalence, so that it is sufficient to model and verify the simpler underlying synchronous designs. We define the HybridSynchAADL language as a sublanguage of the avionics modeling standard AADL for modeling such designs in AADL, and demonstrate the effectiveness of HybridSynchAADL on a number of applications.
