Profile a design to display fixed-point conversion metrics that you use to analyze and adjust data types when converting to fixed-point. When you profile code, the Convert to Fixed-Point tab displays a table of all convertible objects, the data types of those objects, and details to help you configure fixed-point data types that meet your design requirements.
Before you profile the code you plan to convert, make sure that you have already copied the hierarchy of code you want to convert and added it to the testbench. Refer to Adapting a Testbench for Fixed-Point Conversion for help creating a copy of the code you want to convert and setting up your testbench.
