This release introduces the following enhancements to the Fixed-Point Tool:
In previous releases, you access the Fixed-Point Tool by selecting Fixed-Point Settings from the Simulink Tools menu. To display the Fixed-Point Tool in this release, from a model's Tools menu, select Fixed-Point > Fixed-Point Tool. See Opening the Fixed-Point Tool for more information.
In this release, the Fixed-Point Tool incorporates design minimum and maximum values in its automatic scaling procedure. Typically, you use a model object's Output minimum and Output maximum parameters to specify this design range. The tool's Contents pane displays these values in new columns titled DesignMin and DesignMax. See Proposing Scaling for more information.
The Fixed-Point Tool provides a new Autoscale Information dialog box. For each model object, this dialog summarizes data type details and explains the tool's scaling proposal. See Reviewing Scaling Proposals for more information.
See Fixed-Point Tool in the Simulink Fixed Point User's Guide for more information about working with the tool.
The Fixed-Point Advisor is a new interactive tool you can use to facilitate converting a floating-point model or subsystem to an equivalent fixed-point representation. You can use the Fixed-Point Advisor to prepare a model for conversion and obtain an initial scaling to use as the starting point for refinement and exploration inside the Fixed-Point Tool. For more information, see Fixed-Point Advisor in the Simulink Fixed Point documentation.
This section describes enhancements to fixed-point data type support in Simulink blocks.
The Lookup Table (n-D) block now supports fixed-point data types.
The Sum block provides a new parameter for specifying the data type of its accumulator. You can now specify its accumulator data type as any data type that Simulink supports, including fixed-point data types.
