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.

Explore Additional Data Types

Reconvert your design using a new default data type.

View Simulation Results

Use the Simulation Data Inspector to view simulation results and compare runs to verify your fixed-point design.

Restore Model to Original State

Remove changes made during conversion and restore model to state at the start of the conversion process.

Explore Multiple Floating-Point to Fixed-Point Conversions

Iteratively explore different proposal settings to find the best floating point to fixed-point conversion.

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.

Troubleshooting

Data Type Propagation Errors After Applying Proposed Data Types

Troubleshoot when the Fixed-Point Tool proposes data types that are not compatible with the model.
