Note: If you choose to import register values rather than entering them using the GUI, you must specify all
necessary register values. Refer to the
SmartFusion2 User Guide for details.
Exporting DDR Configuration Files
You can also export the current register configuration data into a text file. This file will contain register
values that you imported (if any) as well as those that were computed from GUI parameters you entered
in this dialog box.
If you want to undo changes you have made to the DDR register configuration, you can do so with
Restore Default. This deletes all register configuration data and you must either re-import or reenter this
data. The data is reset to the hardware reset values.
Generated Data
Click OK to generate the configuration. Based on your input in the General, Memory Timing and Memory
Initialization tabs, the FDDR Configurator computes values for all DDR configuration registers and
exports these values into your firmware project and simulation files. The exported file syntax is shown in
Figure 2-4.
