Exida, the independent and internationally recognised specialist for functional safety, has again certified Vector’s MICROSAR Classic Safe basic software up to the highest level – ASIL D. In addition to the regular recertification, the focus of the evaluation was also on proving that the software meets the safety requirements for availability in redundant systems. This means that ECU developers at automotive manufacturers and their suppliers can now use the basic software for autonomous driving functions.
The assessors from Exida evaluated modules from various domains of the basic software. They determined their freedom from interference regarding memory and the correct implementation of the dedicated safety requirements that ensure the availability of redundant systems.
Also, and for the first time, the assessors evaluated the new analysis method introduced in the development of MICROSAR, which ensures upper limits for the execution time of the modules. The limitation of the execution time (WCET, worst-case execution time) ensures the permanent availability of, for example, control commands for steering and braking in autonomous vehicles.
In addition to the scope of the previous assessment, Exida evaluated Vector’s modules for communication via Ethernet and J1939, as well as modules for the safe separation of software on different microprocessor cores.
Vector also offers a safety-relevant solution for high-performance ECUs based on AUTOSAR Adaptive up to ASIL D. An independent certificate is planned for the end of the year.
