VciSimpleRingNetwork

1) Functional Description

This hardware component is a VCI compliant ring, implemented as a combinational daisy-chain and well suited for FPGA implementations.it contains two independant rings for VCI commands and VCI responses. It is composed of two components :

• VciRingInitiatorWrapper? : A VCI-RING protocol converter for a VCI initiator.
• VciRingTargetWrapper? : A VCI-RING protocol converter for a VCI target.
