DDR4/DDR3 SDRAM IP - No DIMM support for XCZU2EG and XCZU3EG devices with the SBVA484 package

Description

Version Found: DDR4/DDR3 SDRAM v1.0

Version Resolved: See (Xilinx Answer 58435)

The XCZU2EG and XCZU3EG devices with the SBVA484 package only have 2 HP banks available.

As a result, there are not enough available I/O to support DDR4 and DDR3 DIMMs.

However, the DDR4/DDR3 IP GUI still shows DIMMs available but with a limited data width up to 32-bits.

Solution

Do not select a DIMM with a reduced data width for the XCZU2EG and XCZU3EG devices with the SBVA484 package as DIMMs are not supported for the device/package combinations.

The DIMMs will be removed from the IP GUI in a future release to prevent confusion.
