After generating an external process binary as shown above using the headers and sources available at $XILINX_VIVADO/data/emulation/ip_utils/xtlm_ipc/xtlm_ipc_v1_0/<supported_language>, you can run the emulation using the following steps:

  1. Launch the Vitis emulation or Vivado simulation using the standard process and wait for the simulation to start.
  2. From another terminal(s), launch the external process such as Python/C++/C.
    Note: If you are running multiple I/O or traffic generator-based solutions on the same machine, then set XTLM_IPC_SOCK_DIR unique to each test case on both emulation terminal as well as external process terminal. For example, setenv XTLM_IPC_SOCK_DIR <test_case_dir> (same environment on both emulation process and external process).
Warning: Xilinx provides an end_of_simulation() API to terminate emulation from master utilities of memory mapped AXI4 and AXI4-Stream interfaces. However, you are warned not to use this method unless there is no way to terminate emulation from host. In a normal course of emulation, external process is not expected to terminate emulation. Use this in exceptional scenarios.
