When using a MPMC SDRAM PHY, I receive the following error during MAP:
"ERROR:LIT:297 - BUFG or BUFGCTRL are the only valid components that can drive
REFCLK pin of IDELAYCTRL symbol
The MPMC_Clk_200MHz is not connected. How do I resolve this issue?
Set the MPMC C_NUM_IDELAYCTRL parameter to '0'. The SDRAM (not DDR or DDR2) PHY does not use IDELAYCTRLs.
A DRC check will be added starting with MPMC v4.00.a in EDK 10.1.
