The Command-Line Interface for the Fixed-Point Tool

The methods of the DataTypeWorkflow.Converter class allow you to collect simulation and derived range data, propose and apply data types to the model, and analyze results. The class performs the same fixed-point conversion tasks as the Fixed-Point Tool. The following table summarizes the steps in the workflow and lists the appropriate classes and methods to use at each step.

Step in Workflow	Primary Objects and Object Functions for Step in Workflow
Set up model	DataTypeWorkflow.Converter

Note

You should not use the Fixed-Point Tool and the command-line interface in the same conversion session.
