Abstract:Abstract. To support model-based development and analysis of embedded systems, the specification language VDM++ has been extended with asynchronous communication and improved timing primitives. In addition, we have defined an interface for the co-simulation of a VDM++ model with a continuous-time model of its environment. This enables multi-disciplinary design space exploration and continuous validation of design decisions throughout the development process. We present an operational semantics which formalizes… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
