i have a program have 5 i/p (clk, reset, sw1, sw2, sw3) and 8 o/p (LED1, LED2, LED3, LED4, LED5, LED6, LED7, LED8), after i successfully downloaded to the cyclone V GX FPGA board starter kit. the results on the output LEDs is not correct, while when i implement the same program on another type of altera FPGA board the correct results is produced. why?? what about this problem in cyclone V GX FPGA board starter kit?

Thousands of reasons... 

Debug your design using SignalTap.

I put some files on the altera wiki a few weeks ago that may help you to understand the Cyclone 5 starter kit, its' HDMI Output & an mSGDMA controller, not the old SGDMA controller.
