IP Product: DDR3 SDRAM Controller MegaCore supporting UniPHY

Warning: Ignored Global Signal option assignment from source signal "PLL output clock name" to destination signal "name"|dll_wys_m -- destination cannot use global signals

Description

You may see this warning when you compile a design using DDR3 SDRAM Controller with UniPHY in Quartus® II software version 11.1SP1 or earlier. This warning can safely be ignored since a global signal assignment is not applied to this dedicated routing from PLL to DLL.

The warning is scheduled to be fixed in a future version of the Quartus II software.
