I Knew MISRA-C Coding Rule is consist of about 140 Coding Rules.
I Wonder this!

What you are asking is not possible.

if you have to ask the question then the answer is :
ALL MISRA-C rules apply from SIL0 to SIL4

MISRA-C forms a language subset.

IEC61508 Part 7 Table C.1 line 10 states that \"C with subset and coding standard, and use of static analysis tools\" is highly recommended at SIL1 thru SIL4.

Our experience is that once people learn how to write MISRA-C conformant code, they just do not think in terms of not writing MISRA-C code.

Given this, I think that MISRA-C should be consistently applied across projects regardless of SIL.
