Coupling of modelling and analysis tools requires that both ends strictly comply with the same semantic definition of the exchanged model. This is particularly important for real-time systems and software architectures. Such a guaranty can be brought by the common use of the Architecture Analysis and Design Language (AADL) all along the tool-chain. This paper discusses modelling and analysis options of various real-time architectural patterns expressed in AADL though an experiment with Stood and Cheddar tools.
