How to get clock signal in the chipscope pro analyzer?
I can add clock in ILA but it is missing in the waveform.

The analyzer is completely synchronous to its own clock. So if you wanted to look at its clock by
also adding it as a data input, then it will be always sampled at the same level because the
sampling is synchronous to its rising edge. You could look at any slower clock, but again
if the clock is not much slower you will see effects of "aliasing" due to the sampling rate.
In the wave viewer of ChipScope, there are tick marks showing the clock periods when
you zoom in far enough. Also the clock periods are counted and a sequence number is
displayed above the tick marks.

I could not find it in the WAVEFORM window of Chipscope. Could you please spot it in the screenshot attached?

Just above the waves themselves is a bar that looks like a ruler labeled 0 80 160 . . .
The tick marks between the 0 and 80 for example will show you individual clock
cycles when you zoom in more. Eventually you get to maximum zoom and each
tick corresponds to 1 clock and the labels instead of 0 80 160 ... will look
like 0 5 10 15 ...

If we can't able to see the input clock signal in chipscope-pro ,then how to conform the input clock signal for the chipscope pro is same as our design clock signal means both signals are having same frequency....help me
