Components Overview
Xilinx® devices contain a variety of components that are dedicated to a specific set of functions and are built into the hardware. The dedicated hardware can be used by explicitly instantiating the components in your HDL or schematic file or by inferring them in your HDL file. For more information, see Instantiation and Inference.
Following are commonly used components for FPGAs and for CPLDs. For a complete list of all the design components, see the Libraries Guide available from the Software Manuals collection.
