Step 5 of 5 in Iterative Fixed-Point Conversion Using the Fixed-Point Tool

After you simulate your model using embedded types and compare the floating-point and fixed-point behavior of your system, determine if the new fixed-point behavior is satisfactory. If the behavior of the system using the newly applied fixed-point data types is not acceptable, you can iterate through the process until you find settings that work for your system.

Edit Proposal Settings

In theConvertsection of the toolstrip, under theSettings菜单,改变Fixed-P建议设置oint Tool uses to generate data type proposals for objects in your system under design.

Propose, Apply, Simulate, Compare

Click thePropose Data Typesbutton to generate data type proposals using the new settings. After examining the new proposals in the spreadsheet, click theApply Data Typesbutton.

View of the Fixed-Point Tool illustrating the iterative workflow: edit proposal settings, propose data types, apply data types, verify system behavior, and repeat as needed.

Iterate

Simulate the model using the newly applied data types and compare the behavior as described inVerify New Settings. Continue to iterate through this process (edit proposal settings, propose data types, apply data types, verify system behavior) until you find settings for which your system's fixed-point behavior is acceptable.

Restore Model to Original State

During thePrepare System for Conversionstep, the Fixed-Point Tool creates a restore point for your model. After the conversion process, if you want to restore your model to its state at the start of the conversion process, in the Fixed-Point Tool, clickRestore Original Model. The Fixed-Point Tool closes your model and reopens the model in its original state. Any changes made to your model after the preparation stage of the conversion are removed.
