Example Driver Limitation for DDR, DDR2, and DDR3 Controllers with ALTMEMPHY


This problem affects DDR, DDR2, and DDR3 products with ALTMEMPHY.

The driver for the example designs for the DDR, DDR2, and DDR3 controllers with ALTMEMPHY contains a design limitation.

If you change the LOCAL_BURST_LEN_s assignment to a value other than default value of 2, the example driver might not behave properly. The resulting improper behavior would affect the design in both simulation and hardware.


There is no workaround for this issue.

This issue will not be fixed.
