Choosing the scaling for the fixed-point variables in your algorithms can be difficult. In the Fixed-Point Designer™ software, you can use a combination of data type override and min/max logging with automatic model-wide instrumentation to help you discover the numerical ranges that your fixed-point data types need to cover. These ranges dictate the appropriate scalings for your fixed-point data types.
