please help

Check also that your code meets RTL rules. Not any code that runs on a simulator will run on the FPGA. So please if you can send your code such that anybody here can guide you especially if you are beginner in this field.

Good Luck

check the power and make sure that the jtag is plugged in the correct way...
there is usually a program that is already on the chip, which makes sure it's functioning well, a counter that displays on the seven segment display or something that lights leds or so
