Abstract
A hard macro-to-user logic interface of an integrated circuit is described. The integrated circuit includes a core as an application specific circuit block with a transaction interface of a first bit width and includes programmable logic capable of being programmed to instantiate user logic. The user logic has a user interface of a second bit width substantially less than the first bit width. A wrapper circuit couples the user interface and the transaction interface for coupling the core to the user logic.
