Step 13: Set the Logic to Processor Cross- Trigger - 2024.2 English

When the Vivado Hardware Session successfully connects to the SP701 board, you see the information shown in the following figure:

1. Select the Settings - hw_ila_1 tab and keep the Trigger Mode Settings with the default value:

   1. Set Trigger mode to BASIC_ONLY.

   1. Under Capture Mode Settings, ensure that Trigger position in window is set to 512.

1. Click on the (+) sign in the Trigger Setup window to add the slot_0 : microblaze_riscv_0_axi_periph_M00_AXI : AWVALID signal from the Add Probes window.

2. In the Trigger Setup window, for slot_0 : microblaze_riscv_0_axi_periph_M00_AXI : AWVALID signal, ensure that the Operator field is set to ==, the Radix field to [B] (Binary) and the Value field to 1 (logical one).

   This essentially sets up the ILA to trigger when the awvalid transitions to a value of 1.

   

3. Click the Run Trigger button to ‘arm’ the ILA in the Status - hw_ila_1 window.

   The ILA immediately triggers as the application software is continuously performing a write to the GPIO thereby toggling the net_slot_0\_axi_awvalid signal, which causes the ILA to trigger. The ILA in turn, toggles the TRIG_OUT signal, which signals the processor to stop code execution.
