Critical Issue
Description
This problem affects DDR2, DDR3, LPDDR2 and RLDRAM II products.
When generating an external memory interface for an Arria V or Cyclone V device, the generation process may fail to complete if you do not have the Stratix V device database installed.
Resolution
The workaround for this issue is to ensure that the Stratix V device database is installed before attempting to generate the external memory interface.
This issue will be fixed in a future version.
