AR# 41965 MIG v3.7 Virtex-6 DDR2/DDR3 - HAMMER data pattern does not work in simulation

The MIG Traffic Generator does not simulate the HAMMER data pattern correctly. Why is app_wdf_data always undriven by the traffic generator even when I set DATA_PATTERN=DGEN_HAMMER in sim_tb_top.v?
This is a problem with the HAMMER pattern process inside v6_data_gen.v and only affects the Verilog design. Please replace v6_data_gen.v with the modified version provided below to resolve the problem.

v6_data_gen.v

This will be fixed with the release of ISE 13.2 software and MIG v3.8.
