Abstract

Due to the increasing complexity of embedded systems, early detection of soft- ware/hardware errors has become desirable. In this context, e ective yet exible speci cation methods that support rigorous analysis of embedded system requirements are needed. Current speci cation methods such as pattern-based, boilerplates normally lack meta-models for exten- sibility and exibility. In contrast, formal speci cation languages, e.g., temporal logic, Z, etc. are too mathematical to be used by the average software engineer in industry. In this paper, we propose a speci cation representation that considers thematic roles and domain knowledge that enable a deep semantic analysis of requirements. The speci cation is complemented by our constrained natural language speci cation framework, ReSA, which acts as interface to the representation. The representation that we propose is encoded in the logic-based, usually de- cidable ontology language called Description Logic. With support from the ontology reasoner, Hermit, we check for consistency and completeness of requirements. Moreover, we transform the ontology-based speci cation into Timed Computation Tree Logic formulas, to be used further in model checking system behavioral models.
