nios system-board switches not responding to eclipse program.

Hi,

I have developed a niosII system. tried to implement count_binary.c file from eclipse library.Now the problem is its not responding to switches. always edge capture detects 0 only .....that is switches of board not responding.

how to check whether it is the problem due to error in switches or not??????

I am using stratixII ep2s60f672c3n board.

    Signal tap is a good place to start from the internals of the FPGA.

    But if you want to see if the switch is doing anything, break out a logic analyzer, or o-scope, and probe the output of the switch. If the board is missing a pull-up or pull-down, that may be your problem.

    Hi,,

    I tried signal tap analizer for switch signals.

    first I did it by independently taking all the switch signals. then I got logic 1 waveform.

    after I did signal tap by combining all the switch signals.then got combilation error as... "can't fit design in device .... is this creating problem my design????

    I have attached screenshot documents .

    please check it.

    Thank you
