i have problem regarding adc of spartan 3e. simulation works well but when i load it into the board. it didnt work. i have used switch 0 to start the conversion. after switch 0 is turned on different values of adc bits appear on leds but after some time they all became high. this process is same regardless of the adc input, even when their is no input same process repeats on leds. i am dubugging it for 3 days but i am unable to find out the problem. please have a look on it.

One post is sufficient. Have you de-bounced the push-button? If not, the pushbutton action will 'bounce' many times, on and off, so your start signal is probably violating all kinds of timing and operation constraints.
