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.
