One of the challenges of design automation in CPS is the deep integration of models, tools and design flows such that design trade-offs across traditionally isolated design disciplines is facilitated. In this paper we overview experience and results gained along the implementation of an experimental design automation tool suite, OpenMETA, created for a complex CPS design challenge in the ground vehicle domain. The focus of the paper is domain agnostic methods and tools providing infrastructure for the model- and tool- integration platforms in OpenMETA. We present the arguments leading to the creation of the integration platforms instead of pursuing ad-hoc integration of heterogeneous tools and provide details on facilitating semantic integration.

A critical non-functional requirement in such systems is to restrict the amount of time, i.e. cause- effect latency, for an input to impact its corresponding output. The problem of estimating the worst-case cause-effect latency is well-studied in the context of blocking inter-task communication. Recent research results show that non-blocking communication preserving functional semantics is critical for the model-based design of dynamically updatable systems. In this paper, we study the worst-case cause-effect reaction latency estimation problem in the context of non-blocking inter-task communication. We present a computationally efficient algorithm that tightly over- approximates the exact worst-case reaction latency in cause-effect data-flow chains.

Designing these systems with a comprehensive model-driven design process, from requirement elicitation to iterative design, can help detect issues, or incongruities within the requirements themselves earlier. This paper discusses how safety, security, and performance require- ments should be assured with a systematic design process, and how these properties can support or conflict with each other as detected during the verification process.
