2.2.2. Using Custom Memory Device Presets from a File

If you want, you can use custom memory device presets that you have saved to a file previously.

To use memory device presets that you have saved previously, follow these steps:

  1. In the Memory Device Preset Selection group box of the External Memory Interfaces IP parameter editor, set Use Memory Device from File to True.
  2. In the Memory Preset Custom File Path field, select the required memory device presets file. (The presets file must have a .qprs file extension.)
  3. In the Memory Preset field, select Custom Preset.

Note: If you are unable to find or select a custom presets file, it might be because your presets file fails to meet the following requirements:
  • The device DQ width in the custom memory device presets file must match the selected device DQ width in the EMIF IP parameter editor.
  • The clock frequency in the custom memory device presets file must match the clock frequency selected in the EMIF IP parameter editor.
  • The custom memory presets file name must have a .qprs extension.
Note: For information on saving custom memory device presets to a file, refer to Generating a Custom Memory Presets file .
