Installation

To determine if the Simulink Fixed Point software is installed on your system, type

ver

at the MATLAB^® command line. When you enter this command, the MATLAB Command Window displays information about the version of MATLAB software you are running, including a list of installed add-on products and their version numbers. Check the list to see if the Simulink Fixed Point software appears.

For information about installing this product, see your platform-specific MATLAB Installation Guide.

If you experience installation difficulties and have Web access, look for the installation and license information at the MathWorks™ Web site (http://www.mathworks.com/support).

Sharing Fixed-Point Models

You can edit a model containing fixed-point blocks without the Simulink Fixed Point software. However, you must have a Simulink Fixed Point software license to

• Update a Simulink diagram (Ctrl+D) containing fixed-point data types

• Run a model containing fixed-point data types

• Generate code from a model containing fixed-point data types

• Log the minimum and maximum values produced by a simulation

• Automatically scale the output of a model using the autoscaling tool

If you do not have the Simulink Fixed Point software, you can work with a model containing Simulink blocks with fixed-point settings by doing the following:

1. Access the Fixed-Point Tool from the model by selecting Tools > Fixed-Point > Fixed-Point Tool.

2. Set the Fixed-point instrumentation mode parameter to Force off model wide.

3. Set the Data type override parameter to True doubles or True singles model wide.

Note   If a parameter in your model specifies a fi object, you can prevent the checkout of a Fixed-Point Toolbox™ license by setting the fipref DataTypeOverride property to TrueDoubles. See Licensing for more information.

This procedure allows you to share fixed-point Simulink models among people in your company who may or may not have the Simulink Fixed Point software.

Demos

To help you learn how to use the Simulink Fixed Point software, a collection of demos is provided. You can explore specific features of the product by changing the parameters of Simulink blocks with fixed-point support and observing the effects of those changes.

The demos are divided into the following groups:

• Application Examples

• Feature Demonstrations

• Filters

• Tools and Utilities

• Custom S-Function Examples

All demos are located in the fxpdemos directory.

To view the complete list of demos, see Simulink Fixed Point Demos.
