set_instance_assignment -name DQ_GROUP 9 -from ddr3_rdimm_a_dqs[8] -to ddr3_rdimm_a_dq[65]

set_instance_assignment -name DQ_GROUP 9 -from ddr3_rdimm_a_dqs[8] -to ddr3_rdimm_a_dq[66]

set_instance_assignment -name DQ_GROUP 9 -from ddr3_rdimm_a_dqs[8] -to ddr3_rdimm_a_dq[67]

set_instance_assignment -name DQ_GROUP 9 -from ddr3_rdimm_a_dqs[8] -to ddr3_rdimm_a_dq[68]

set_instance_assignment -name DQSB_DQS_PAIR ON -from ddr3_rdimm_a_dqsn[8] -to ddr3_rdimm_a_dqs[8]

that I am going to go look for more info on.
