Target Function Library Limitations :: Replacing Math Functions and Operators Using Target Function Libraries (Real-Time Workshop® Embedded Coder™)

Target Function Library Limitations

Target function library (TFL) replacement may behave differently than you expect in some cases. For example, data types that you observe in a model do not necessarily match what the code generator determines to use as intermediate data types in an operation. To verify whether you are obtaining the function or operator replacement that you expect, inspect the generated code.
To analyze replacement behavior, in addition to referencing the generated code and examining your TFL tables in the TFL Viewer, view the TFL cache hits and misses logged during the most recent code generation session. This approach provides information on what data types should be registered in order to achieve the desired replacement. For more information on analyzing TFL table entries, see Examining and Validating Function Replacement Tables.
You must register TFL in the sl_customization.m or rtwTargetInfo file, but not in both files.
