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

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.
