2.1.1.2. Saving a Memory Device Presets File
After you have configured the parameters, you can save your configuration as a presets file.
To save your configuration, type the desired name for your presets file, with the extension .qprs, and click Save configuration.
Figure 7. Configuration Save/Load Dialog Box
Note: Ensure that you save the presets file with the extension .qprs. Ensure that the high-level parameters and timing parameters match the custom preset file (for example. Memory Format, Device DQ Width, Memory Clock Frequency, etcetera).
