ID:130003 <name> primitive "<name>" is configured to drive both DQS and nDQS buses simultaneously. All <name> destinations with parameter <name>="TRUE" must be driven by this <name> on the same CLK or CLKN port.
CAUSE: The specified DQS_DELAY_CHAIN
is configured to drive more than one physical DQS bus (for example, DQSBUS
and nDQSBUS
). The DQS_DELAY_CHAIN
drives the clk
and clk_n
ports of several DDIO_IN
primitives. These DDIO_IN
primitives have the use_clkn
WYSIWYG parameter set to true
, indicating that they are operating in QDR mode. While in QDR mode, DDIO_IN
clk
ports are driven by a DQSBUS
, while DDIO_IN
clkn
ports are driven by a nDQSBUS
.
ACTION: Ensure that the DQS_DELAY_CHAIN
drives DDIO_IN
primitives through exactly one port type clk
or clk_n
when use_clkn
is set to true
. If you want the DQS_DELAY_CHAIN
to drive both clk
and clk_n
ports of the same DDIO_IN
, set the use_clkn
parameter of all DDIO_IN
primitives to false
in the DDR mode.
