MIG UltraScale DDR4/3 - Designs targeting dual rank DIMMs with address mirroring fail in hardware

Description

Version Found: MIG UltraScale v6.1
Version Resolved: See (Xilinx Answer 58435)

Dual Rank DIMMs that use address mirroring require specific rtl within the MIG IP to support the address mirror between ranks.  

While MIG generates designs for dual rank DIMMs that use address mirroring, the rtl is not modified to support the mirroring and as a result the addressing is incorrect.  

This will cause hardware failures.

Solution

Until this is resolved, If you are targeting dual rank DIMMs using address mirroring in hardware, please open a webcase for assistance.
