PMC&CMU Error Injection

Pusoy — Fri, 22 Dec 2023 09:52:15 GMT

Hi,

Recently, I have been using the PMC and CMU modules, but I haven't found a way to inject related exceptions to validate my program logic.

1. For the PMC module, is there a way to inject voltage exceptions? (such as injecting high or low voltage exceptions for VDD_HV_A)
2. For the CMU module, is there a way to inject frequency exceptions? (such as injecting high or low frequency exceptions for CMU_FC0)

Thank you very much!

Hello,

I have a development board based on the S32K344 chip, with the model S32K3x4_HDQFP172, as shown in the picture below.

Additionally, I also have a chip S32K312.

1. Can these two devices inject PMC&CMU errors? If so, please provide the methods.

Thank you very much, I am looking for your replay!

Hello,

No PMC nor CMU injection is possible here. Nor required.

This is all covered by SAF:

refer to safety manual for more details.

Best regards,

Peter
