Software support

TI's software support includes:

  • A safety compliance support package according to IEC 61508, including software documentation and testing to assist in compliance with functional safety standards. The package includes safety requirements documents, code review and coverage reports, unit test results and software safety manuals. It ideally includes unit test capability using tools such as a Liverpool Data Research Associates (LDRA) unit.
  • Safety tool documentation and qualification according to IEC 61508 that assists in the qualification to functional safety standards, including a tool classification report, tool qualification plan and report, tool safety manual, and test automation unit.
  • A safety diagnostic library that provides interfaces and a framework for initializing and enabling safety diagnostics/features, fault injection to allow the testing of application fault handling, a handler callback routine, and profiling for measuring time spent in diagnostic test/fault handling.
  • Development tools assessed and/or certified as suitable for use with IEC 61508, including integrated development environments and compilers and Joint Test Action Group emulators/traces.
