Why does Timequest Report DDR not display the timing margin results of slave interfaces for UniPHY memory interface IP?

You may also see these type of warning messages :

Warning (332087): The master clock for this clock assignment could not be derived.  Clock: <mem_ck_name> was not created.

Warning (332049): Ignored set_output_delay at <IP_name>_p0.sdc(407): Argument -clock with value [get_clocks {mem_dqs[1}] contains zero elements.

For details of the flow, see the DLL and PLL Sharing Interface section in the Functional Description - UniPHY chapter in volume 3 of the External Memory Interface Handbook.

In addition to the flow steps, if the master inst name contains a "\" in the hierarchy path name, it must be converted to "\\" to be recognized correctly in the <IP_name>_p0_timing.tcl script.

This issue is planned to be fixed in a future version of Quartus® II software.
