Any changes in addressing of the source block design of a BDC will not be reflected in the top-level block design. Because 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.
In addition to viewing and changing the address of sub-block designs, you can:
- Map Masters to Slaves inside the sub-block design in the top-level block design or vice-versa.
- Modify the addressing of the sub-block design to fit into the apertures of the top block design.
- View multiple instantiations of the same source block design that have different set of addresses for their Masters and Slaves.
