DDR Controller Designs in AFI Mode with Memory Burst Length of 2 Fail in Simulation

Description

Designs that use the full-rate DDR SDRAM high-performance controller in AFI mode with a memory burst length of 2 fail to simulate.

This issue affects all designs that use DDR SDRAM high-performance controller in full-rate mode with a memory burst length of 2.

As the generated memory model does not support memory burst length of 2, your design fails to simulate.

Workaround/Fix

Use a vendor memory model instead.

This issue will not be fixed in a future version of the DDR SDRAM Controller with ALTMEMPHY IP.
