In current model-based development practice, validation that we are building a correct model is achieved by manually deriving requirements-based test cases for model testing. Model validation performed this way is time consuming and expensive, particularly in the safety critical systems domain where high confidence in the model correctness is required. In an effort to reduce the validation effort, we propose an approach that automates the generation of requirementsbased tests for model validation purposes. Our approach uses requirements formalized as LTL properties as a basis for test generation. Test cases are generated to provide rigorous coverage over these formal properties. We use an abstract model in this paper
