The ILA cores that you add to your design appear in the Hardware window under the target device. If you do not see the ILA cores appear, right-click the device and select Refresh Device. This re-scans the FPGA or adaptive SoC and refreshes the Hardware window.
Click the ILA core (called hw_ila_1 in the following figure) to see its properties in the ILA Core Properties window. You can see all the probes corresponding to the ILA core by using themenu option, which displays the Debug Probes window as shown in the following figure.
