Faults and failures may be life threatening so automotive systems are demanding higher levels of functional safety. Enabling functional safety from classic automotive applications such as anti-lock braking systems to sophisticated Advanced Driver-Assistance Systems (ADAS) and autonomous driving is a priority. Software Test Libraries allow checks to be performed for some functions without the need for high levels of redundant hardware.

Software Test Libraries enable both boot-time and runtime diagnostic checking. Boot-time diagnostics (which can be destructive) execute rapidly as the system is coming online and help check system function before the main application starts. Run time diagnostics execute during normal system operation and therefore must not destroy any data and must complete their specific function in a clearly defined time, called the worst case execution time.

Integrate Software Test Libraries into your application. Make use of standard API and scheduler with your bare metal implementation or with your Operating System and allow to take appropriate action whenever the STLs detect a designated fault. Build together with your hypervisor to assure software separation for simplified integration.
