MIG v3.1, Virtex-6 DDR2/DDR3 - Non-zero values for Additive Latency are not supported

Description

The MIG v3.1 tool allows selection of different Additive Latency values on the Memory Options screen.

However, the DDR2 and DDR3 Virtex-6 MIG designs only support an Additive Latency value of 0.

Solution

Please ensure that the Additive Latency selection in the MIG tool is set to 0. 

Non-zero values are not supported.  

This option is removed from the MIG tool in MIG 3.2.
