ID:186324 Fan-out node "<name>", from combout port of DQS I/O pin "<name>", must be DDIO bidirectional pin
CAUSE: You either used the altdqs megafunction or assigned the
DQS Phase Shift
and
DQS Frequency
logic options to the specified DQS I/O pin. However, the fan-out of the combout
port of the DQS I/O pin is not the input clock port of a DDIO bidirectional pin. All combout
port fan-outs must be to the inout
clock port of DDIO bidirectional pins.
ACTION: Modify the design so that all combout
ports fan-out to the input clock port of DDIO bidirectional pins that have their input registers implemented in the I/O (not LCells); or delete the DQS Phase Shiftand DQS Frequency logic option assignments on the DQS I/O pin.
