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
