Why Does the Fixed-Point Converter App Not Propose Data Types for System Objects?
The Fixed-Point Converter app might not display simulation range data or data type proposals for a System object™ because:
The app displays range information for a subset of DSP System Toolbox™ System objects only. For a list of supported System objects, see Converting System Objects to Fixed-Point Using the Fixed-Point Converter App.
The System object is not configured to use custom fixed-point settings.
If the system object is not configured correctly, the proposed data type column appears dimmed and displays
Same as...to show the current property setting.
