ID:130010 Found single T7 DELAY_CHAIN primitive "<name>" on DQS postamble/sampling path. The Compiler expects two T7 delay chains on the DQS postamble/sampling path, which are connected in series.

CAUSE: The specified DELAY_CHAIN primitive appears on the DQS postamble/sampling path, and will be mapped to a physical T7 delay chain location. The Compiler expects to either find two T7 delay chains in the DQS postamble/sampling path connected in series, or no T7 delay chains in the path at all.

ACTION: Either instantiate an additional T7 delay chain, connected in series with the specified delay chain in the DQS postamble/sampling path, or remove the specified delay chain from your design.
