Developing Dependable Software-Intensive Systems: AADL vs. EAST-ADL


Publication Type:

Conference/Workshop Paper


International Conference on Reliable Software Technologies




Dependable software-intensive systems, such as embedded systems for avionics and vehicles are often developed under severe quality, schedule and budget constraints. As the size and complexity of these systems dramatically increases, the architecture design phase becomes more and more significant in order to meet these constraints. The use of Architecture Description Languages (ADLs) provides an important basis for mutual communication, analysis and evaluation activities. Hence, selecting an ADL suitable for such activities is of great importance. In this paper we compare and investigate the two ADLs – AADL and EASTADL. The level of support provided to developers of dependable software intensive systems is compared, and several critical areas of the ADLs are highlighted. Results of using an extended comparison framework showed many similarities, but also one clear distinction between the languages regarding the perspectives and the levels of abstraction in which systems are modeled.
