Reusable Verification Framework
This article demonstrates how to write interface connections only once and use them in both block- and system-level testbenches. The order is not important: System-level testbenches can be written without all the blocks of the DUT completed, DUT and UVM blocks can easily be interchanged. Taking care not to use virtual interfaces in the UVC but Bus Functional Models (BFM) in the interface instead – so called polymorphic interfaces, UVCs can be fully configurable as well as reusable.
