      4.2 Vivado

    ................................................................................
    5. KNOWN ISSUES

      5.1 ISE

        The following are known issues for v7.1 of this core at time of release:

        1. Virtex-6 and Spartan-6: BRAM Memory collision error, when the user selects TDP (write_mode= Read First)
          Work around: The user must review the possible scenarios that causes the collission and revise
           their design to avoid those situations.
          - CR588505

          Note: Refer to UG383, 'Conflict Avoidance' section when using TDP Memory - with
                Write Mode = Read First in conjunction with asynchronous clocking

        2. Power estimation figures in the datasheet are preliminary for Virtex-5 and Spartan-3.

        3. Core does not generate for large memories. Depending on the
           machine the ISE CORE Generator software runs on, the maximum size of the memory that
           can be generated will vary.  For example, a Dual Pentium-4 server
           with 2 GB RAM can generate a memory core of size 1.8 MBits or 230 KBytes
          - CR 415768
          - AR 24034
