Explore Additional Data Types

After you simulate your model using embedded types, and compare the floating point and fixed-point behavior of your system, determine if the new 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.

Warning

Collecting ranges after you apply proposed data types will reset the workflow. You will no longer be able to easily propose and apply new default data types after collecting ranges.

Edit Proposal Settings

In the Convert Data Types section of the toolstrip, under the Settings menu, alter the proposal settings that the Fixed-Point Tool uses to generate data type proposals for objects in your system under design.

Propose and Apply

Click the Propose Data Types button to generate data type proposals using the new settings. After examining the new proposals in the spreadsheet, click the Apply Data Types button.

Iterate

Simulate the model using the newly applied data types and compare the behavior as described in Verify 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.
