Vitis Subsystem (VSS) enable the development, testing, and delivery of AI Engine graphs and PL kernels packaged as a platform-independent subsystem. VSSs allow for the simulation of the subsystem without the need for a hardware platform, making it faster and more flexible. You can configure and rebuild the VSS component for testing on multiple devices, making it ideal for feasibility studies, custom library development, and reusable modules. For more information, refer to Vitis Subsystem Flow.
Selecting Vitis Subsystem as the Export Type links the AI Engine graphs and PL kernels in your design to a <design_name>.vss deliverable. The Export Directory contains this file. You can use the VSS component in either the Vitis Integrated Flow or the Vitis Export to Vivado Flow.
