Automated Static Analysis with best AUTOSAR C++14 Results

Their goal is nothing less than to revolutionize the software in the automotive industry: Apex.AI, a Palo Alto, Munich, and Berlin-based company, is developing breakthrough safe, certified, developer-friendly, and scalable software for mobility systems. For the development of Apex.OS, a safe, secure and reliable software communication layer for self-driving applications, and Apex.Middleware, a complete and integrated solution for both intra- and inter-ECU communication, Apex.AI was looking for a tool for automated static analysis which fulfills strict requirements customary in the automotive industry.

THE CHALLENGE ++

Apex.AI can count numerous big names among its supporters and customers: Strategic investors like Toyota Ventures, Volvo Group Venture Capital, Jaguar Land Rover’s InMotion Venture, Airbus Ventures, and Hella Ventures have put their money in the company. In early 2021, Toyota’s Woven Planet announced its cooperation with Apex.AI for developing and deploying a production-ready autonomy stack for Toyota’s vehicle development platform Arene. The expectations of investors and customers regarding the future viability of Apex.AI’s products are high – and the company is positioning itself toactively shape the future of mobility.

Apex.AI’s software products are based on proven open-source software: The award-winning Apex.OS has been forked from ROS 2 and has been developed into a real-time, reliable, and erministic safety framework and middleware for safety-critical applications for all mobility systems from autonomous vehicles to robo-taxis and automated trucking. Apex.Middleware is based on Eclipse iceoryx, another open-source solution resulting from a collaboration between Bosch and Apex.AI engineers in Germany and serves all applications from power train over ADAS to automated driving.

Apex.OS and Apex.Middleware are the backbone for many automotive software platforms which need to meet highest standards especially in software-defined and autonomous vehicles. Therefore, Apex.AI had been looking for a tool to support their product development and their efforts to build safe algorithms. Automated static analysis is the best way to safeguard the software’s quality on thelong run – but it must become a natural part of the developers’ daily work routine by fully integrating the tool into the established developer environment CLionand the continuous integration infrastructure at Apex.AI. Furthermore, a fully suitable tool must be on top of the industry standards in the automotive sector: Being compliant with the latest AUTOSAR C++14 style guides is decisive for success as well as the tool’s certification for the ISO 26262 standard up to ASIL D.

THE SOLUTION ++

Apex.AI thoroughly evaluated several static code analysis tools in a detailed proof of concept, and soon was convinced to have found the perfect match with the Axivion Suite. The proven tool suite helps to improve software quality and to maintain software systems implemented in C, C++ and C#. Axivion’s MISRA checker covers 100 percent of all automatically testable rules of MISRA C:2004, MISRA C:2012, and MISRA C++:2008. The tool also supports the CERT® programming rules for secure software development and rules for C Secure Coding (ISO/IEC TS 17961) and CWE.

Apex.AI especially valued Axivion Suite’s broad coverage of the AUTOSAR C++14 standard for the development of critical and safety-relevant automotive software, which is a continuation of the MISRA C++:2008 rule set. On top of that, the Static Code Analysis (SCA) package of Axivion Suite is certified for its suitability in safety-critical systems according to ISO 26262 up to ASIL D. This made the tool suite an important cornerstone in the Apex.AI’s own safety certification process for Apex.OS and Apex.Middleware.

Another important argument in favor of Axivion Suite was its ease of integration: The tool suite is designed to fit seamlessly into an existing IDE and customerspecific Continuous Integration processes and DevOps environments. The integration at Apex.AI was accompanied by Axivion’s experienced Professional Services Team, which helped to make the tool suite an immanent part of Apex.AI’s workflows and to teach the developers how to effectively use the tools.

In the end, Axivion Suite performed best in the trials in which it was rigorously compared to other static analysis tools: It was scoring highest for AUTOSAR C++14 coverage, ease of use, control flow and data flow analysis, and report generation.

THE SUCCESS ++

From day one after integration, Axivion Suite fulfilled its new role at Apex.AI: By monitoring the compliance of the code with the AUTOSAR C++14 rules, by providing the developers withanalyses on their control and data flow and by allowing them to easily add exceptions and suppressions to rule violations in C++.

The developers especially appreciate the tool’s ease of use and its seamless integration with the cross-platform IDE CLion, the company’s build system and the overall continuous integration workflows. Axivion Suite helps the Apex.AI engineers to continuously analyze their source code in the build process and ensure their code quality.

The biggest initial success of Axivion Suite at Apex.AI, however, was its role in the certification of Apex.OS and Apex.Middleware. Axivion was single handedly responsible for many of the artefacts submitted to TÜV Nord as part of the certification process. Furthermore, they helped to prove that Apex.AI developers were writing AUTOSAR C++14 compliant code, with no control or data flow issues. So thanks in part to Axivion, Apex.OS is the world’s first certified opensource operating system that has been certified to ISO 26262 ASIL D, the highest level of automotive risk management.
