Using const function pointers in Safety critical code

Hi Akshay,
We are not the certification body so we can not comment and give you consultation if your specific software implementation meet the SIL4 criteria. You seem to create a software jump table using array of function pointers. You might need to make sure the index you pass is within bound of the array.

Yes array bounds will be checked before each jump. But the argument given by many V&V team is not to use function pointers in safety coding. For example reference on this link : spinroot.com/.../P10.pdf (Rule 9). MISRA C has no violations in using const function pointers.

Is there any TI Forums where such questions can be discussed?

Hi Akshay,
Thanks for sharing the link. There is no TI forum that can support this discussion. Since your code is meant to be certified for SIL4 I will suggest you contact the proper authority in safety coding for advice. Note that certification will involve more than just coding but also testing, documentation and etc.

Thanks for the info :) It would be good if TI started such a forum where people can discuss problem and ideas(not just problems in TI products) :)

Hi Akshay,
Unfortunately, I think a forum group as such to recommend coding guideline for SIL4 certification is unlikely to be offered from TI.
