12.3 EDK, MPMC - ERROR:EDK:3900 - issued from TCL procedure

Description

When using the integrated MPMC MIG GUI Flow, I can select for a system clock "Differential" or "Single-Ended".

However, when I select "Single-Ended", PLATGEN generates the following error. How do I resolve it?

ERROR:EDK:3900 - issued from TCL procedure
"::hw_mpmc_v6_02_a::syslevel_drc_mig_flow" line 88
C_USE_MIG_FLOW (IPNAME:mpmc, INSTANCE:DDR2_SDRAM_W1D32M72R8A_5A) - There have
been changes to this design that have changed the number of external memory
pins for MPMC instance DDR2_SDRAM_W1D32M72R8A_5A. Please re-run the MIG gui
from the IP Configurator to generate the correct constraints.

Solution

The selection of Single Ended or Differential System Clock does not affect the MPMC.

Keep the system clock selection default as "Differential".
