System ILA not working

Jump to solution

I have a system ILA in my design. When pressing the 'Run trigger' button, I receive the error message:

[Labtools 27-3428] Ila core [hw_ila_1] clock has stopped. Unable to arm ILA core.

The ILA clock input is connected to the output clock of a GTP receiver (see images). I'm sure that the clock is active because the design is actually working in H/W. What am I missing when using the system ILA?

(Vivado HL Design Edition 2018.2.2, Artix-7).

Hi Andre

I have re-built the H/W, and now the System ILA works with the GT0_RXUSRCLK2.

I don't understand what happened, but it seems that my initial problem (not working System ILA) was caused by something else.

Hi @luminal101,

 

The GTP transceiver is not considered a free-running clock, so that's not allowed to clock the ILA.

You'll need to find a different clock for it.

Thanks,

Re: System ILA not working

Ok, I understand. But then what is the correct way to monitor the GTP output data stream? I could imagine something like this:

  • Generate a free-running clock at the same frequency as the GTP RX clock
  • Route the GTP AXI Stream through a clock domain crossing and into the ILA

Or is there a better way to do it?

Thank you for your help!
