In the latest revision of the core, there have been several changes to ensure pin-incompatibility with the previous core versions. These changes were required as part of the general one-off hierarchical changes to enhance the customer experience and are not likely to occur again.
As part of the hierarchical changes to the core, it is now possible to have the core itself include all of the logic which can be shared between multiple cores, which was previously exposed in the example design for the core.
RECOMMENDED: When updating from a previous version to a recent version with shared logic, there is no simple upgrade path and AMD recommends that you consult the Shared Logic sections of this document for more guidance.
