ChipScope & Vivado Logic Debug - How can I trigger two ILA cores at the same time?


I need to use two ILAs in my project to trigger with different clocks or instantiate in two modules.

How can I trigger two ILAs at the same time?


To do this you will need to have a controllable external trigger (for example hitting the reset pushbutton on the board first) or a predictable trigger.

Follow the steps below:

  1. Make sure the trigger condition does not occur first.
  2. Hit the "Run Trigger" button in ChipScope analyzer or the Vivado Hardware Manager for both ILA.
  3. Make the trigger condition happen.

When the capture buffers are full, the waveform for both ILAs will be uploaded and shown on the screen.
