High Performance DDR2 Controller

I'm developing a DDR2 High Performance Controller. When the megawizard was done, it said to make the <instance_name>_example_top_level.vhd as the top-level file. Do I only want to do that to test the DDR2 High perfromance controller? Is that test for simulation or for hardware tests?

When my design is complete and I've added the rest of my logic, I only want to instantiate the <instance_name>.vhd correct, not the <instance_name>_example_top_level.vhd?

Thanks!

    I use the ddr3 version and noticed the same thing. I just added the .QIP file to my project, and simply ignored the example_top stuff. I get a pile of warnings associated with not using it, but they seem harmless. I would be interested to hear any better ideas!

    The "_example_top_level.vhd" file is just a top level example file for testing.

    When I go instantiate my DDR2 controller component (as in add to the entire system), do I just instantiate my <instance_name>.vhdl or is there another file that I need to instantiate?

    Thanks
