The .xo file is a format of IP that can be used by the shell in the Vitis flow. DPU IP files are released as .xo files.
  1. Download the DPUCAHX8H_xo_gen_flow.tar package to generate DPU .xo files. The package includes DPU-related encrypted RTL and timing constraint files.
  2. cd to the path: DPU_v3e_xo_gen_flow.
  3. Run the following command to generate the DPU .xo files with required options.
    vivado -mode tcl -source gen_DPUCAHX8H_ENGINE_xo.tcl -tclargs [1-5]ENGINE FREQ card(u50/u50lv/u280)

    For example, to generate 5ENGINE 275M xo for the U50LV implementation, run the following command:

    vivado -mode tcl -source gen_DPUCAHX8H_ENGINE_xo.tcl -tclargs 5ENGINE 275 u50lv

The interface of the DPU xo is as following figures (3ENGINE, 4ENGINE, 5ENGINE). Each ENGINE uses one AXI port, so the DPU_AXI_* port number is the same as ENGINE number of the xo.
