Modular development and verification of domain requirements via model checking

A holistic domain model of a software product line is costly to build and difficult to verify and evolve. We propose a framework to incrementally develop domain requirements and to iteratively verify behavioral properties through model checking. We leverage state vectors to derive both local and global properties, and co-develop statechart models with temporal specifications in a modular way. We illustrate our framework using a worked example. The study shows that our framework can effectively detect inconsistencies and tighten the development feedback loop by automatically verifying domain properties.
