How to share OCT between QDRII and QDRII+ SRAM Controller with UniPHY and DDR3 SDRAM Controller with ALTMEMPHY?

Description

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[0]

 

4.    Add pin location assignment to termination_blk0~_rdn_pad and  termination_blk0~_rup_pad
