Fixed-Point Tool
Convert floating-point model to fixed-point
Description
In conjunction with Fixed-Point Designer™ software, the Fixed-Point Tool provides convenient access to:
An interactive automatic data typing feature that proposes fixed-point data types for appropriately configured objects in your model, and then allows you to selectively accept and apply the data type proposals
Model and subsystem parameters that control the signal logging, fixed-point instrumentation mode, and data type override
Plotting capabilities that enable you to plot data that resides in the MATLAB®workspace
Most of the functionality in the Fixed-Point Tool is for use with the Fixed-Point Designer software. However, even if you do not have Fixed-Point Designer software, you can configure data type override settings to simulate a model that specifies fixed-point data types. In this mode, the Simulink®software temporarily overrides fixed-point data types with floating-point data types when simulating the model.
Open the Fixed-Point Tool
From the SimulinkAnalysismenu, selectData Type Design>Fixed-Point Tool.
From a subsystem context (right-click) menu, selectFixed-Point Tool.
From the MATLAB command prompt, enter
fxptdlg(system_name)
wheresystem_name
is the name of the model or system you want to convert, specified as a string.
