Resolve Range Analysis Issues
Different types of range analysis issues can occur in the Fixed-Point Tool depending on the specifics of your model.
Replace Unsupported Blocks
If the model contains blocks that are not supported for fixed-point conversion, range analysis will fail and the Fixed-Point Tool generates an error. Review the error message information and replace the unsupported blocks. For more information, see Model Compatibility with Range Analysis.
Fix Design Range Conflicts
If the model contains conflicting design range information, the analysis cannot derive range data and the Fixed-Point Tool generates an error. Examine the design ranges specified in the model to identify inconsistent design specifications and modify them to be consistent. For more information, see Fixing Design Range Conflicts.
Specify Additional Design Range Information
If there is insufficient design range information specified, the analysis cannot derive range data and the Fixed-Point Tool highlights the results. Examine the model to determine which design range information is missing. Specify additional range information or reconfigure the code so that the Fixed-Point Tool can derive ranges for the model. For more information, see Insufficient Design Range Information and Troubleshoot Range Analysis of System Objects.
