I am using iterative fixed point conversion on a simulink state flow model. When executing the "Collect Ranges" using double precision, the following error is given:

Ranges could not be collected for the model.

Caused by:

Error due to multiple causes.
In cg_cast_or_assert: Cast failed

If I rung "Collect Ranges" with using current settings option then fixed point tool is unable to propose data types for some data. The following error is given for these:

"The data type of this result is inherited. The Fixed-Point Tool cannot remove data type inheritance from all results. "

Please suggest a way forward to successfully convert the model to fixed point.

Dear Andy,

Thank you very much for getting in touch. Please find attached the reduced model. I have also attached a snapshot of the screen showing my System-Under-Design setting. Let me know if you require more details.
