ddr3_addr[12] is not driven by the user but by MIG and is used for burst chop mode, which is enabled through a mode register during initialization.
A[12] determines (on the fly) whether or not burst chop is used during a READ and WRITE.
If A[12] is not being driven, make sure the following parameter is set properly in the test bench:
constant C0_BURST_MODE : string := "8";
When C0_BURST_MODE is not set correctly in the user test bench, 'X' will be seen for ddr3_addr[12] in simulation.
