Domain specific languages allow users to directly express domain concepts in their programs and thereby eliminate the accidental complexity resulting from implementation details irrelevant to the domain. Cleaner programs, written in DSLs are much easier to analyze formally. However, domain specific analyses need to be implemented over and over again for each new domain specific language. In this paper we show that the use of language engineering techniques for modularizing languages can drastically improve on this situation. Language fragments (aka. language modules) together with a set of analyses defined for them can be reused between different DSLs, making the implementation of analyses significantly easier. This paper presents our approach for using the Meta-Programming System to implement domain specific languages and analyses both as extensions of C and in the domain of intelligent buildings. The main lesson learned is that modularization at language and analysis level allows rapid instantiation of advanced DSLs and their corresponding analyses.
When verifying C code, two major problems must be addressed. One is the specification of the verified systems properties, the other one is the construction of the verification environment. Neither C itself, nor existing C verification tools, offer the means to efficiently specify application domain-level properties and environments for verification. These two shortcomings hamper the usability of C verification, and limit its adoption in practice. In this paper we introduce an approach that addresses both problems and results in user-friendly and practically usable C verification. The novelty of the approach is the combination of domainspecific language engineering and C verification. We apply the approach in the domain of state-based software, using mbeddr and CBMC. We validate the implementation with an example from the Pacemaker Challenge, developing a functionally verified, lightweight, and deployable cardiac pulse generator. The approach itself is domain-independent.
The E/E (electric/electronic) architecture of a modern vehicle is a complex distributed system, where up to 80 electronic control units (ECUs), interconnected by several communication buses, need to collaborate with each other in order to implement the various comfort and safety features. The presented E/E design space exploration framework supports engineers during the development process of new E/E architectures by providing a graphical modeling and simulation environment with an interactive visualization of simulation-based results. Furthermore, it contains an advanced business logic which administrates the modeling, storing, retrieving and cloning of evaluation sessions consisting of complex experiments. Due to a high-level modeling approach, future architectures can be evaluated in respect to power consumption and performance values already in an early stage of the design process and design alternatives can be easily compared with each other.
