Hi,

Just add reset signal, and give trigger on that, then press reset button, if in this case also same problem comes then your clock is not running. Make some counter which runs on clock (used by chipscopro) and assign 27th bit to led available on your board and varify.

Hello arun,

I faced the same pronblem as you. TYhe solution is simple, you must read the input system clock , probably a Xtal Oscillator, then invert it at any output port
i.e.

sys_clk_in <= sys_clk_out

Then while connecting the ILA core use system_clk_in as the clock for ythe core.Everything should be okay now.

Best wishes,

hi,
thanks for the replies........
i have one more doubt. i have many components in my code. i am not able to understand what all nets to be connected to the trigger and data signals. i thought of connecting the top module nets but all the inputs and outputs are not available and many intermediate nets are present of different components. i think my problem would be solved if i can know what all signals to be triggered.

but iam not able to understand it. please help.

do i need to trigger all the nets available.

No, you do not need to trigger on all nets in the system. Just set chipscope to start capturing data on the reset signal as was mentioned above. Or if you know that your system starts with some specific values without having go use reset, then choose those values.

Also its a good idea to maintain hierarchy when using chipscope. XST flattens your design by default.
