* Safety function VIM2A / DMA5 A / HET7A / ADC5A / CAN4A / ETH4A

I using TMS570LS3137, and reading Safety Manual(SPNU511D).

Can all these be detected by PBIST?
Can I also individually detect individual safety functions?
If the above contents are correct, please tell me about each failure occurrence method and distinction method.

    Hello Falcon,

    Yes, this Diagnostic is covered by PBIST. HALCoGen generates 2 PBIST function: pbistSelfCheck() and pbistRun(). pbistCheck() is used to perform PBIST self test. The pbistRun() is used to perform Memory Built-in Self test using PBIST module.

    Not all algorithms are designed to run on all RAM groups. If an algorithm is selected to run on an incompatible memory, this will result in a failure. In pbistSelfCheck() generates error by using a wrong algorithm for a specified RAM GROUP.
