11.4 EDK, MPMC v5.04.a - ERROR:HDLCompiler:559 - "v6_ddrx_control_io.v" Line 3517: Could not find module/primitive


When using MPMC v5.04.a and earlier in Virtex-6 FPGA withthe registered memory setting of PARAMETER C_MEM_REG_DIMM = 1, the following error occurs:
ERROR:HDLCompiler:559 - "/build/xfndry/EDK_LS5.70/rtf/hw/XilinxProcessorIPLib/pcores/mpmc_v5_04_a/hdl/verilog/v6_ddrx_control_io.v" Line 3517: Could not find module/primitive <u_obuf_parity>.
ERROR:EDK:546 - Aborting XST flow execution!

How do I resolve this error?


This issue is fixed in MPMC v6.00.a, to be released in EDK 12.1.

Note that MPMC v6 for Virtex-6 FPGA requires some manual updating to the MHS and UCF files.See the MPMC v6 data sheet for detailed directions to upgrade.
