when i run the chipscope analyzer, I'm able to capture the datas. But i cant capture the clk signal. is there anyway to capture the clock signal as well?
When you are using the CLK signal for trigger/clock you can't see it!
You must have an additional signal with higher frequency (for example x2 or more) and this signal is use for the chipscope trigger/clock, now u can see your CLK signal.
For this you can instantiate a DCM (Data Clock Manager).

hi,
In fact the Chipscope only makes state analysis!
