Towards a DOM-Based Requirements Models Analysis for Automotive Software

Modeling software requirements is one of the grand challenges of Electronic Control Unit (ECU) development for vehicular applications. One of the main problems in this domain is: How to organize the large amount of complicated software requirements with a concise and manageable means. EAST-ADL2, as an architecture description language, dedicated to automotive electronic systems, is well-suitable for describing system structures. However, correctly modeling automotive software requirements using EAST-ADL2 is difficult. In this paper, we build a syntax analyzer for EAST-ADL2 domain models on top of an XML DOM tree. The tool takes the following advantages that: (1) it can effectively eliminate errors related with an EAST-ADL2 domain model; (2) it can be easily integrated in the EAST-ADL2 modeling environment; (3) it can interoperate with other tools developed using this approach.
