IP Product: DDR3 SDRAM Controller MegaCore supporting UniPHY

Why do I see a Qsys warning for the pll_sharing conduit even when the PLL sharing mode option is set to 'No Sharing' in the UniPHY Megacore settings?

Description

The pll_sharing conduit is exposed in Qsys even when the UniPHY Megacore's PLL sharing mode is set to 'No Sharing'.  This will cause Qsys to issue a warning "**_pll_sharing must be exported, or connected to a matching conduit."  The pll_sharing conduit is forced to be exposed because users need access to the pll_locked signal. 

Workaround/Fix

Users may ignore this warning as it will not affect Qsys generation.

This warning will be fixed in a future version of Quartus® II software.
