An IP integrator block design can act as the highest level in the design hierarchy or be integrated into a higher‑level design. To integrate it into a higher‑level design, instantiate the block design as a module within the higher‑level HDL file.
You can instantiate a block design at a higher level by selecting it in the Sources window of the Vivado IDE. Select Create HDL Wrapper to generate a top-level HDL file for the IP integrator sub-system. For details, refer to the Vivado Design Suite User Guide: Designing IP Subsystems Using IP Integrator (UG994).
