I'm not sure I understand your question, but if it is a value that you want to be fixed by external means (by the PCB itself, or using configuration straps / dip switches / connectors) then you need to assign the input pins in your project to the relevant FPGA pins.

If it is a value that you fix in your Quartus project then you don't need to use FPGA pins at all.

I don't really get how this is related to DDR memory.
