  • Support of system integration with application-dependent tests
  • Handling of internal and external watchdogs (SafeWDG)

AURIX™ TC3xx Safety Software SBST Deliverables

SBST for non LS CPU – supporting ASIL-B

  • The CPU Software Based Self Test (SBST) is a safety mechanism that supports the ISO26262 SPFM for ASIL B safety goals. The SBST detects Permanent Random Hardware Faults in the fetch unit and pipelines of non-lockstep CPU cores with a diagnostic coverage level of 90%.
  • Required for applicants with an ASIL B requirement on AURIX™ TC3xx non-lockstep CPUs.

SBST for SPU – supporting ADAS cluster ASIL-C applications

  • The SPU Software Based Self Test (SBST) is a safety mechanism that supports the ISO26262 SPFM and is similar in concept to the CPU SBST described above.
