I'm trying to use ILA to debug my design on Arty a7 board. However, I am not being able to get any waveform dump.
1) The ILA clock seems to be running. I routed this clock to one of the LEDs, and I see the LED is lit. Furthermore, when I turn off that clock via a switch (forcing the generating PLL to reset), and attempt an immediate trigger, I get "no clock is connected to this ILA" message which I don't get when the switch is flipped back on.
2) Design meets timings
3) Vivado's interaction with the FPGA via USB seems to be fine at least for loading the design, and USB-UART. I have a UART transceiver in the design which I have tested already and it seems to be working as expected.
4) I am using Vivado 2018.3 on an Ubuntu 16.04 machine.
When I click the immediate trigger, the ILA stays in the "Idle" state.
Can someone please tell me what I am missing, or guide me on how to continue my debug? Could it be that the ILA is actually getting a capture in the FPGA, but the capture somehow never makes it to Vivado through JTAG-USB?
