Use the Trigger position control in the Capture Mode Settings window (or the Trigger Position property in the ILA Core Properties window) to set the position of the trigger marker in the captured data window. You can set the trigger position to any sample number in the captured data window. For instance, in the case of a captured data window that is 1024 samples deep:
- Sample number 0 corresponds to the first (left-most) sample in the captured data window.
- Sample number 1023 corresponds to the last (right-most) sample in the captured data window.
- Samples numbers 511 and 512 correspond to the two "center" samples in the captured data window.
You can also use the set_property Tcl command to change the ILA core trigger position:
set_property CONTROL.TRIGGER_POSITION 512 [get_hw_ilas hw_ila_1]
