Note:

It is important to strictly follow the pin placement for a given memory topology when assigning pin locations for your EMIF IP.

Do not change the location for the EMIF pin using a .qsf assignment or the Pin Planner if you need to swap the DQ pins within a DQS group or the DQS group to simplify board design.

Refer to the Configuring DQ Pin Swizzling topic in the External Memory Interfaces Intel Agilex® 7 M-Series FPGA IP Design Example User Guide for more information on how to swap the DQ pin and DQS group.

For dual-rank component interfaces, you cannot have different swizzling specifications for rank 0 and rank 1.
