more questions about signal tap

Whoa, thanks!! I think I see what you're saying. SignalTap samples the signals at the acquisition clock frequency and stores it in the device buffers. I can specify how many such samples [sample depth] I want to see after the trigger happens.

To get an accurate representation of the signal, my acq clock should be atleast 2x the frequency of the signal [Nyquist frequency]. To be safe, maybe 10x, if Signal Tap can take it. I read the maximum clock freq is 200MHz.

If my acquisition clock does not go high at all, Signal Tap samples nothing, so 128k samples [sample depth] of nothing get stored in the SRAM when trigger [power up trigger] happens. so my output is garbage -- just SRAM init states [ah, I ran the analysis on that!].

The time for which the analysis runs, is the time taken for the buffers to get full after the trigger happens.

I'm just re-iterating my understanding. Correct me, please, if I am wrong.

Thanks a million :) :)
