QDRII vs QDRII+ in Virtex-6

ISE11.4's MIG V3.3 support QDRII+ for Virtex-6, but the QDR memory we will use is QDRII.  I wonder if I go thru the GUI for MIG for QDRII+, and input the value for all the timing parameters in the GUI based on the QDRII device's datasheet, will the generated interface work for QDRII memory?

 

Thanks,

CZ

Re: QDRII vs QDRII+ in Virtex-6

QDR II is not supported in MIG for V6.  However, you will find a parameter (MEM_TYPE) in the generated QDR II+ design that can be used for QDR II.  You may need to update some other parameters as well.  You are on your own for this as it is unsupported.  You need to simulate and test this in your system.  Xilinx does not support it.
