Please refer to this answer record if you are not able to simulate all data_modes with a small Spartan-6 device.

The testbench provides a parameter, C_SMALL_DEVICE, which limits the tests you can run in simulation. Xilinx provides this parameter because some of the data patterns require too much logic to fit into a smaller Spartan-6 device. This essentially prevents an error during MAP.
