4. RESOLVED ISSUES

The following issues are resolved in Block Memory Generator v6.2: 
  
  1. Core errors in NGDBuild when the depth is too large (especially for Spartan-6 devices)
   Version Fixed: v6.2 
   - CR 587481
   - AR 39718

5. KNOWN ISSUES 

The following are known issues for v6.2 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
