Now that the system is built, we can test it in HW emulation.
Right-click on the simple_application_system and click Run As → Launch HW emulator.
On the Launch On Emulator pop-up window click Start Emulator and Run
Note You can use the option Launch Emulator in GUI mode to display waveforms to open Vivado Simulator and observe the waveform from the PL signals. If you select this option make sure you run the simulation in Vivado simulator as QEMU will wait for it.
You should see the application running successfully with no error in the Vitis Emulation console.
To stop the emulator click Xilinx > Start/Stop Emulator and click Stop
