MIG Virtex-6 v3.5 DDR2/DDR3 - Synthesizing design using Synplify Pro D-2010.03 fails during BitGen


MIG Virtex-6 v3.5 available with ISE 12.2 supports Synplify D-2009.12 as noted in the MIG Virtex-6 Release Notes (Xilinx Answer 36211).

If the unsupported version of Synplify D-2010.03 is used with MIG Virtex-6 v3.5 BitGen errors will occur.


This is a result of a software bug with Synplify D-2010.03 where RAM is initialized incorrectly causing BitGen errors.

To prevent these errors please use the supported version D-2009.12 with MIG Virtex-6 v3.5.
