From section 5.1 of the AUTOSAR standard, the "header file Mfx.h provides all public function prototypes and types defined by the Mfx library specification."
The “limits.h” header file is unrelated to the CRL or AUTOSAR at all – it determines the limits (max and min values that can be represented) for variable types.
This header file is included when there are fixed point data types in the model and fixed-point word size checks are enabled. Please note that "limits.h" is not generated by MathWorks Coder products but rather is a C header file that determines the limits for different variable types. The limit for each type is the max and min values that can be represented by the type.
The reason why we include this header file is to perform some checks on the target (e.g., because fixpoint slope/bias can cause overflow). These checks can be disabled with the setting
.
