Safety Mechanism Empty Area in FMEDA

[HeebeomPark]

The following is a part of Flash Safety Mechanism.

Why the safety mechanism is empty?  The following can cover for latent?

• SM1.EDC_after_ECC

• SM2.FLASH.SCHECK

• SM1.FLASH.AI_SELFCHECK

i think the following SM for FCCU that is latent. Why the safety mechanism is empty?

The following can be covered by "SM2.STCU.SWCHECK"? 

what about the following? Can you give us any recommendation? Even safety manual does not mention it.

Hi Heebeom,

Failure of the FOSU, MBIST, STCU are consider safe fault as there are features to test the safety mechanisms. Therefore there would be consider "triple point fault that are safe for the application".
