In this flow, sub-block designs are created separately and the you need to instantiate these sub-blocks as BDCs within the top-level block design. The designer or a team lead can integrate all of them by following the steps below:
- Add the sources of the existing sub-blocks to the top-level BD project as explained in the Adding Existing Block Designs section in Adding Existing Block Designs .
- Drag the added BDs from the Sources window onto the top-level BD diagram. Alternatively, you can right-click on the top-level BD diagram and select Add Module.
