AutoSAR software is certified to ASIL D

Certification has been issued for the AutoSAR 4 basic software from Vector, confirming that it fulfills the requirements of ISO 26262 up to the ASIL D level. According to the company, it is the first to offer software that has been certified by an independent assessment. This lets developers implement significantly higher performance ECUs (engine control units) for safety-related applications.

To ensure that safety-related and non-safety-related software components do not interfere with one another, their data is usually stored in separate memory areas. This software allows them to be executed in the same partition as the safety-related application software. This approach significantly increases performance, because task switching, reprogramming of the memory protection unit (MPU) and additional copying can be eliminated, explains the company. Safety requirements that were previously implemented on the application level can now be allocated to the basic software.

In the assessment, the OS and the software components for CAN, LIN and FlexRay communication were evaluated as were the components for system control and memory management.

Particular focus was the use of special verification methods to achieve full coverage for the specific user configuration despite the high configurability of the modules. In the assessment, it was verified that all software modules were sufficiently free from interference. Extensive semi-formal design and traceability records were also created for the assessed components.

The software is distributed under the name MicroSAR Safe. It is available for all of the microcontrollers typically used in the automotive industry.
