How to log waveform of AIE configuration port #88

Hi all,
I'm running the aie_adder demo in hw_emu flow, and I want to log all signals' waveform when running hw_emu
the way I log all waveform is that add below info in xrt.ini

[Emulation] 
user_pre_sim_script=<use pre sim script absolute path>

and my pre-sim.tcl is just log_wave -r *

After running the launch_hw_emu.sh and exit the QEMU, I could find dr_behav.wcfg in my behavior sim folder, and when open it in vivado, I could find the hls and aie interface wave, below is the hls kernel mm2s interface waveform

Based on above result, I think my workflow is correct

When I open the block design of this project, I find that the S00_AXI is connected to the cips_noc IP, and other *_AXIS is connected to hls kernel, two slave and one master

Based on AM009 documentation, AIE array has a configuration port, AXI master could write instruction into AIE Tile program memory using this AXI bus, I guess this AXI bus in block design is S00_AXI, so that the PS could config the AIE using this axi bus

However when I check the waveform of this axi bus, there is no data transfer on this bus, and the waveform shows below

Is this bus port used as aie configuration? how could I know the aie boot mechanism, especially how to config the AIE array, and how to start AIE? is there any doc to describe this?

Another thing is that can I just run PL+AIE without PS code? is it possible to start AIE through PL rather than PS?

Thanks!
