  2. Edit the xrt.ini file in SD_card with the following content, and reboot the board:

    aie_profile = true
    interval_us = 1000
    graph_based_aie_metrics = all:all:execution
    tile_based_aie_memory_metrics = all:dma_locks
    tile_based_interface_tile_metrics = all:output_throughputs:0
  3. Move the obtained profile data in the directory, profile_2, in a local workspace.

  4. Open the first profile run summary file in the Vitis Analyzer as explained in step 4.

  5. Add the second profile run summary file to the existing run_summary file using the + option as shown below. Observe the combined metrics of first run with the heat_map, conflicts, and input_throughputs metrics and the second run with execution, dma_locks, and output_bandwidth metrics in the Vitis Analyzer. multiple view
