Validation of Embedded Systems Behavioral Models on a Component-Based Ericsson Nikola Tesla Demonstrator

Embedded systems are challenging to design, due to the implementation platform constraints that have to be considered, preferably from early stages of design, next-by system functionality. Hence, embedded system models need to be timing and resource-aware, to make formal verification of extra functional properties applicable at high levels of abstraction. In most cases, a frequent obstacle to the successful application of such rigorous techniques is the lack of the proposed models´validation against real-world application measurements. In this paper, we show how to model extra-functional behavior, and verify the resulted behavioral models of a component-based Ericsson Nikola Tesla prototype telecommunications system. The models are described in our recently introduced REMES language, with Priced Timed Automata semantics that allows us to apply UPPAAL -based tools for model-checking the system´sresponse time and compute optimal resource usage traces. The validation of our models is ensured by using actual values of timing, CPU, and memory usage in our models, measured by Ericsson researchers on the prototype´s source code.
