Worst case Performance analysis of Embedded Networks – WoPENets

Submission summary

For critical embedded networks like in avionics, automotive and satellites with hard certification requirements to respect and where a failure might have a disastrous consequence on the system, deterministic guarantees on temporal and functional constraints are of the utmost importance. Having the opportunity to conduct worst-case performance analysis till the first steps of the design process will be great for the designer to choose the right system’s parameters which respect the required constraints before investing too much time in detailed implementations. In order to enhance the design process time and costs of embedded networks, our proposal consists in integrating a new aided-decision tool named WoPENets (Worst case Performance evaluation of Embedded Networks).

This tool embodies an analytical approach to perform a system level worst-case performance evaluation and includes optimization analysis to find the optimal design solution that guarantees the system’s requirements till the first steps of the design process. This tool will integrate high level models of the most common critical embedded networks like Real Time Ethernet for automotive and train, the AFDX for avionics, Spacewire for satellites and Network on Chips. WoPENets will be easy to use by any designer without any specific knowledge of the used analytical formalism thanks to a simple and ergonomic interface. There is already a prototype of WoPENets and our objective in this project is to achieve a high maturity level to propose this tool to industrial designers.
