Accelerate Safety Compliance
Arm Software Test libraries (STL) complement Arm’s functional safety technology which supports systematic capability for ISO26262 ASIL D. STLs are efficient assembly language routines that test for the presence of faults when executing on Arm-based processors at startup and during run time. A single straightforward C language application programmer interface (API) lets developers quickly and easily scale test functions across multiple CPU systems.
Features and Benefits
Arm Software Test Libraries undergo an extensive functional safety assessment process, that helps developers shrink time to market and give them the confidence their system will meet industry safety standards.
Boot diagnostics (which can be destructive) only execute as the system is coming online when there is less of a real-time execution requirement, thus avoiding the chance of mishap in a running system.
Runtime diagnostics execute during normal system operation and therefore must not destroy any data and must complete their function in a defined time, called the worst-case execution time.
Industry standards require that diagnostics test for the widest possible number of faults. Arm’s in-depth knowledge of its processors means we offer top-class diagnostic coverage of potential faults.
Arm Software Test Libraries have size-optimized code and require fewer memory resources, leaving more available for the target application software and helping to reduce cost.
Arm Software Test Libraries take maximum advantage of built-in processor features that enable rapid test execution and short test granularity reducing impact on other system functions.
