14. Upgrading to UniPHY-based Controllers from ALTMEMPHY-based Controllers

The following topics describe the process of upgrading to UniPHY from DDR2 or DDR3 SDRAM High-Performance Controller II with ALTMEMPHY Designs.

NOTE: Designs that do not use the AFI cannot be upgraded to UniPHY. If your design uses non-AFI IP cores, Intel recommends that you start a new design with the UniPHY IP core . In addition, Intel recommends that any new designs targeting Stratix III, Stratix IV, or Stratix V use the UniPHY datapath.

To upgrade your ALTMEMPHY-based DDR2 or DDR3 SDRAM High-Performance Controller II design to a DDR2 or DDR3 SDRAM controller with UniPHY IP core, you must complete the tasks listed below:

  1. Generating Equivalent Design
  2. Replacing the ALTMEMPHY Datapath with UniPHY Datapath
  3. Resolving Port Name Differences
  4. Creating OCT Signals
  5. Running Pin Assignments Script
  6. Removing Obsolete Files
  7. Simulating your Design

The following topics describe these tasks in detail.
