A Summary of Safety Features and Diagnostics

Table A-1 Summary Table Legend
Unique Identifier Identifier used to reference the contents.
Safety Feature or Diagnostic Safety feature
Usage Each test listed in this chart can be one of three types: a "diagnostic" test, a "test for diagnostic", or a "fault avoidance" measure.
Diagnostic: Provides coverage for faults on a primary function of the device. It may, in addition, provide fault coverage on other diagnostics, and can therefore be also used as a test-for-diagnostic in certain cases
Test-for-Diagnostic Only: Does not provide coverage for faults on a primary function of the device. It's only purpose is to provide fault coverage on other diagnostics
Fault Avoidance: This is typically a feature used to improve the effectiveness of a related diagnostic.
Diagnostic Type Hardware - A diagnostic which is implemented by TI in silicon and can communicate error status upon the detection of failures. It may require software to enable the diagnostic and/or to take action upon the detection of a failure.
Software - A test recommended by TI which must be created by the software implementer. This test may use additional hardware implemented on the device by TI.
Hardware / Software - A test recommended by TI which requires both, diagnostic hardware which has been implemented in silicon by TI, and which requires software that must be created by the software implementer.
System - A diagnostic implemented externally of the microcontroller
Diagnostic Operation This can be one among the following:
(i) Bootup (enabled by default)
(ii) Continuous - Enabled at reset: Hardware safety mechanism that is enabled by default at reset.
(iii) Continuous - Enabled by software: Hardware safety mechanism that needs to be enabled by software.
(iv) On demand (Software defined): Software or Hardware-software safety mechanism that gets activated in the diagnostic test interval by the software
(v) System defined: Implemented by the system.
Test Execution Time This column lists the time required for this diagnostic to complete.
Action on Detected Fault The response this diagnostic takes when an error is detected.
For software-driven tests, this action is often software implementation-dependent.
Error Reporting Time Typical time required for diagnostic to indicate a detected fault to the system. For safety mechanisms where fault detection time is known, this value is indicated. For software-driven tests, this time is often software implementation-dependent.
