Model Checking of CHAM Descriptions of Software Architectures

In this paper we show how to de ne and prove di erent properties of a software architecture description based on the CHAM. We consider both structural properties, that is properties of the system which are connected with its structure either static and dynamic, and functional properties, that is properties on how the system manipulates its data. We will use a logic approach to describe the properties and a model checking approach to verify them. As case study we take the software architecture of a sender-receiver system.
