7.1 System Generator for DSP -- Why can I not use Fixed Point outputs with MATLAB R14.2, or why do I receive a "Fixed Point blockset not installed" error when setting my output Gateway to use the Simulink Fixed Point data type?

Description

Why can I not use Fixed Point outputs with MATLAB R14.2, or why do I receive a "Fixed Point blockset not installed" error when setting my output Gateway to use the Simulink Fixed Point data type?

Solution

This is a result of a bug in System Generator that causes it to fail to detect the Fixed Point blockset in MATLAB R14.2.

To work around this problem, you must do the following:

1. Set the Gateway Out data type to double.

2. Connect the output of the Gateway Out to a data type conversion block from MATLAB.

3. Set the output type to the format that your need for your application.
