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


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.


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.
