+
+== 1) Functional Description ==
+This hardware component is a VCI compliant ring, implemented as a combinational daisy-chain and well suited for FPGA implementations. It must only be used in clusterized architecture, to interconnect a limited number of VCI initiators and targets in a local sub-system.  
+
+Policy arbitration uses a circulating token which allows the wrappers to access the ring in a round-robin fashion.
