Board files define external connectivity for Vivado. Board files information is available in the IP integrator when you select a board, as opposed to a part, when creating the project. Board interfaces can be enabled in the IP integrator by selecting the appropriate interface in the Boards tab in Vivado. For more information, see Vivado Design Suite User Guide: Designing IP Subsystems using IP Integrator (UG994) and Integrated Interlaken up to 150G LogiCORE IP Product Guide (PG169).
