Vivado Hardware ILA-no waveform

board: zcu102
tools: Vivado2018.2
problems:
            My design works under 16MHz clock, at this time, I can get the expected data from the serial port, but I can't see any waveform on Hardware ILA.
If I set the clock to 100MHz, then i can see the waveform.  Whether the clock is directly from PS or through the clock wizard,get the same phenomenon.design_1.pngila-wave.png

Hi liu2015@ 

This is probably because yoy forgot to set a trigger + run the ILA. This is something I discuss in my Video Series 31 – Debugging a Video System using an ILA . Refer to the lab3 part.

Hi, Florent
Thanks for reply.
I set a trigger and run the ILA, it doesn't work. I guess it's something about free of clock.

Hi liu2015@ 

What trigger did you set? Are you sure you armed the ILA (to start triggering)?

On your screeshot the ILA is IDLE which means that the ILA was not armed.

You need to click on run to arm the ILA:

What do you get if you click on run immediate trigger button14.jpg?

This is all explained in my video series, I hope you read it
