A Vitis platform is comprised of a hardware and a software design that targets a specific device. A Vitis platform design comes with specialized properties indicating that it is a platform capable of connecting to Vitis components. Using Vitis tools and flows, various components can be connected to the platform, including AI Engine graphs, HLS kernels, and PS applications. This chapter discusses the various types of platforms and guides you through the process of creating and validating them. Subsequent chapters will focus on the creation and building of different types of Vitis components.
