Verify Fixed-Point Conversion

Compare fixed-point and floating-point model behavior

After you have completed the steps described in Convert to Fixed Point, compare the simulation behavior of the fixed-point version of your model with the floating-point baseline you collected at the start of the workflow to determine if the conversion was successful.

Model Multiple Data Type Behaviors Using a Data Dictionary

Learn how to use referenced data dictionaries to store multiple sets of data types for a model. This example also shows how to change the data types by switching the referenced data dictionary.


Data Type Propagation Errors After Applying Proposed Data Types

Under certain conditions, the Fixed-Point Tool may propose a data type that is not compatible with the model.
