This section provides the high-level details related to what a system integrator must consider during the process of defining and building their F280013x-based safety architecture.
The software support for the various safety mechanisms in the F280013x is provided by the Software Diagnostic Library (SDL), which provides a series of examples of safety mechanisms that are designed to detect permanent faults inside several key elements within the F280013x device.
To determine which versions of the SDL software library have been evaluated for UL 60730-1 Class-B compliance, refer to the UL product iQ database file number E352502 or to your TI sales representative.
The SDL supports safety mechanisms, such as: CLK10 - Software Test of Watchdog (WD) Operation, CLK12 - Software Test of Missing Clock Detect Functionality, SRAM14 - Software Test of Parity Logic, SRAM13 - Software Test of ECC Logic, SRAM3 - Software Test of SRAM, and several other key processing elements. The system integrator must study all the safety mechanisms and determine their applicability into the safety system being designed. The safety system must be evaluated with respect to the startup and runtime constraints and whether the software diagnostic tests can be run during POST, PEST, or a combination of both.
