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.

All addressing of a BDC sub-block must happen from the top-level block design. The 'Address Editor' of top block design as shown below provides all addressing information for IPs present in the sub-block designs. It also allows the user to view and change addresses of sub-block designs.

In Addition:

  • 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.
