The provided implementations of the generic functions implement a behavior that

is numerically correct and matches the SystemBuild Simulator's results. Any change to the
generic functions can severely affect the numeric results of a model. Do not attempt to
change the implementation unless you are fully aware of the intricacies of fixed-point
numerics.

frequently overflowing, a different data type should be selected. If you are
concerned about performance and the use of an exception handler for
detecting overflow, the generic functions can be changed. These changes do
not affect the generated code in any way. Thus, you can freely modify the
generic function implementations without having to regenerate the model.
Support for the AutoCode/Ada Fixed-Point architecture is found within
files in the System-Specific Files
the fixed-point specific files. Notice that the
Ada compiler you use.
