Entering and
Editing Inputs to
the DTW If you use the Altera legacy controller MegaWizard as a starting point for
your memory interfaces, follow the import flow described below to enter
and edit inputs to the DTW. The legacy controller MegaWizard is the
recommended tool, and simplifies entry of the essential design
requirements. If you have an interface that is not supported by the legacy
controller MegaWizard , refer to
“Manual Flow for Other External
Memory Interfaces or Source Synchronous Systems” on page 2–14 .
