During the development of software intensive systems, typically several models of this system are designed. These various models represent the system structured by different concerns, e. g. abstraction. While these approaches help to cope with complexity, the need of relating the models to one another arises. A major task is to keep model specifications consistent and traceable through special relations. The relation of interest for this work is the refinement relation between abstraction levels. In this work we describe a technique to check the validity of these refinement relations with respect to formal behavior/interface specifications of design items. For evaluation, we apply our refinement technique to an industrial example modeled with the contract-based methodology from our previous work.
