Bring Support for Zephyr Analysis to ARA

ARA is a program to statically analyze a real-time system to extract all operating system instances (like threads) together with their interactions (what thread interact with this queue?). Currently, it is able to analyze applications written for FreeRTOS (providing dynamic instances only) and the OSEK API (providing static instances only).

Zephyr is a full-featured RTOS guided by the Linux Foundation. It support static and dynamic instances and provides a high amount of configuration options. The goal of this thesis is to bring support for Zephyr analysis to ARA.

The tasks that should be done in the thesis are:

• Extend the existing RTOS model to support Zephyr.
• Implement the necessary analysis steps.
• Evaluate the implementation with appropriate Zephyr based real-time systems.

Topics covered by this thesis:
real-time systems, static analysis, LLVM, C++, C, Python
