4. Choose the location from which to import the data. Select

<core_variation_name>_<ddr|qdr|rldramii>_settings.txt from the

project directory. The example in Figure 2–6 uses a the DDR2

SDRAM controller named legacy_core, so the DTW must import

data from the legacy_core_ddr_settings.txt file generated by the

legacy controller MegaWizard.

Figure 2–6. Choose the <core_variation_name>_<ddr|qdr|rldramii>_settings.txt File to be Imported

5. The DTW then imports data from the

<core_variation_name>_<ddr|qdr|rldramii>_settings.txt file.

This process may take some time if your design is large.
