You can implement OCT sharing between QDRII and QDRII+ SRAM Controller with UniPHY and DDR3 SDRAM Controller with ALTMEMPHY by the following steps:
1. Create your project including a DDR3 SDRAM Controller with ALTMEMPHY and QDRII and QDRII+ SRAM Controller with UniPHY. Set OCT sharing mode as Slave in QDRII and QDRII+ SRAM Controller with UniPHY.
2. After analysis and synthesis, run <IP name>_pin_assignments.tcl
3. Add following assignment to Q, CQ and CQN for QDRII SARM interface.
set_instance_assignment -name TERMINATION_CONTROL_BLOCK " termination_blk0" -to mem_q
4. Add pin location assignment to termination_blk0~_rdn_pad and termination_blk0~_rup_pad
