To use the IP generated from Vitis Model Composer, you need to create a new project. Alternatively you can open an existing project that targets the same device as specified in Model Composer for creating the IP.
Select IP Catalog in the Project Manager, and right-click an empty area in IP catalog window. Select Add Repository, and add the directory that contains your new IP.
After adding the IP to the IP catalog, you can include it in larger designs. Do this as you would with any other IP in the IP catalog.
