Any changes in addressing of the source block design of a BDC will not be reflected in the top-level block design. Since the sub-block design has adapted to the addressing specifications of the top-level block design, the local addressing of the source BD is lost to top-level block design.
- User can map Masters inside the sub-block design to Slaves in the top-level block design or vice-versa.
- User can modify the addressing of the sub-block design to fit into the apertures of the top block design.
- Multiple instantiations of the same source block design can have different set of addresses for their Masters and Slaves.
