External Memory Interfaces Targeting Some Stratix V Devices Do Not Function Correctly in Hardware

Environment

  • Quartus® II Subscription Edition
    • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    This problem affects DDR2, DDR3, QDR II, RLDRAM II and RLDRAM 3 products.

    External memory interfaces using pins in banks 7E or 8E of the following Stratix V devices will not function correctly in hardware:

    5SGXBB

    5SGXB9

    5SGXAB

    5SGXA9

    5SEEB

    5SEE9

    The cause of this problem is that connections from levelling delay chains to I/O banks are swapped for banks 7E and 8E in the software model for the affected devices.
