The Fixed-Point Tool uses ranges collected during this phase of the conversion process to propose data types for your model. Do this step after you have prepared your system for conversion Prepare System for Conversion. You can collect ranges through simulation with instrumentation, range analysis, or a combination of the two. To determine which approach you should use, see Choosing a Range Collection Method.

Convert data types in your model to fixed point in one of three ways.
Use the Fixed-Pint Tool to convert a system from floating point to fixed point.
This example shows how to use the Fixed-Point Tool to compare floating-point and fixed-point data types.
There are three methods for collecting ranges on which to base data type proposals.

Summary of range analysis support for Simulink® blocks.
Overview of software features that are not supported for range analysis.
Maintain integer data types in your model when using data type override.
Troubleshoot range analysis issues.
If you specify conflicting design minimum and maximum values in your model, the range analysis software reports an error.
If the analysis cannot derive range information because there is insufficient design range information, you can fix the issue by providing additional input design minimum and maximum values.
How to proceed if the analysis cannot derive range information because there is insufficient design range information.
