See Using the Vitis Software Platform for more information. In general, after you generate the bitstream for your design, you are ready to export your hardware definition to the Vitis software platform.
This action exports the necessary files needed for the Vitis software platform to understand the IP used in the design and also the memory mapping from the perspective of the processor. After a bitstream is generated and the design is exported, you can then download the device and run the software on the processor.
For detailed procedure, see Exporting a Hardware Description.
