FMEDA for S32

[johan_samuelsso]

Hi

I have started looking into the FMEDA analysis that we have received from our NXP support representative. My understanding is that we should update the Peripheral sheet depending on how we use the MCU. Are there any guidance available how this shall be done? For example, should I add all pins used as GPIOs as seen in row 64 (Pin example)? Also, how shall the document be adapted if not using e.g. the LPUARTs?

BR,

Hi

We provide failure rates for application dependent peripherals and IOs. You need to take these failure rates and analyze them in your FMEDA. For example, of all the pins you may have only few pins that are safety related depending upon your application. And so failure rate of other pins may not be considered in the analysis.

Hi Aarul

So where do I find the failure rates for application dependent peripherals and IOs? What I found is the number in the FMEDA Summary sheet: Peripheral Failure Rates (ISO 26262-5 D.1: Digital I/O, Analog I/O, Communication).

Is it this number that shall be distributed?

BR,

You should look at the Peripheral FMEDA.

We have received the FMEDA configured for our application. I have checked the files but what I'm missing is how to adapt the Peripheral FMEDA.

Hi Johan

The peripheral FMEDA only contains failure rates. Our recommendation is that based on your application and safety relevance of the peripherals, you can perform the FMEDA in the ECU level FMEDA.
