Beginner FPGA and Stepper motor

I have a question about FPGA and stepper motor I want to make use of the output voltage of FPGA to provide the voltage for stepper motor. However, i have no idea how to connect them tgt. ...

you wont be able to use the GIPO pins to directly power a stepper motor, but that GIPO pin can be used to send pulses which will be the step and dir signal to a driver circuit. Look up easydriver, this chip will take step and direction signal generated from the FPGA and convert it to motor movement.

your top entity is where you'd declare your pins and then use pin planner to assign that pin to your pin location. You can then use whatever pin name you called it and map it to your verilog module.
