You can log simulation minimum and maximum values for MATLAB
Function blocks using the
Mininums, maximumx and
overflows logging control in the Fixed-Point Tool. The logged
minimum and maximum values are displayed in the MATLAB Function Report.
For fixed-point data types, the report also displays the percent of
current range. You can use the simulation minimum/maximum data to
help you determine the optimal word length and fraction length of
fixed-point data types for signals in your model. After modifying
your model to use fixed-point data types, simulate again to verify
that the data types cover the full intended operating range.
Note: The software does not log simulation minimum and maximum values for MATLAB Function blocks used as a reference (library) block or in a referenced model.
