Overview of the Fixed-Point Tool

Introduction to the Fixed-Point Tool

The Fixed-Point Tool is a graphical user interface that automates the task of specifying scaling for fixed-point data types in a model. The tool collects range data for model objects, either from design minimum and maximum values that objects specify explicitly, or from logged minimum and maximum values that occur during simulation. Based on these values, the tool proposes fixed-point scaling that maximizes precision and covers the range. The tool allows you to review the scaling proposals and then apply them selectively to objects in your model.

Opening the Fixed-Point Tool

Use any of the following methods to open the Fixed-Point Tool:

Alternatively, you can use the fxptdlg function to open the tool programmatically.

Understanding the Interface

When you first open the Fixed-Point Tool, it appears as shown here.

The Fixed-Point Tool contains the following components:
