3.2 Software Support

To enable customers on their safety journey, TI provides a ASIL-D/SIL-3 safety assessed Software Diagnostic Library (SDL) that covers system level diagnostics and safety features. The SDL is a collection of initialization/configuration, self-test, runtime, and response handler APIs that support various safety mechanisms. It is a fully self-contained library with no dependency on external software and provides an OS Abstraction Layer (OSAL) supporting implementation in both OS and non-OS (baremetal) environments. A compliance support package (CSP) is also provided alongside the SDL to support customers in re-qualification efforts on their system.

Both the SDL and CSP can be accessed via mysecuresw and access can be requested here.
