The waveform debugging process can be enabled through the v++ command using the following steps:
  1. Enable debug features in the kernel code during compilation and linking, as described in Building the Device Binary.
    v++ -g ...
  2. Create an xrt.ini file in the same directory as the host executable, as described in xrt.ini File, with the following contents:
    [Emulation]
    debug_mode=batch
  3. Run the application, host and kernel, in hardware emulation mode. The waveform database, reflecting the hardware transaction data, is collected in a file named <hardware_platform>-<device_id>-<xclbin_name>.wdb. This file can directly be opened in the Vitis analyzer as described in Using the Vitis Analyzer.
    Tip: If debug_mode=gui in the xrt.ini, a live waveform viewer is launched when the application is run, as described in Waveform View and Live Waveform Viewer. This is especially useful when debugging a hw_emu hang issue, because you can interrupt the simulation process in the simulator and observe the waveform up to that time.
