 // This component emulates an external IO bus such as PCIe or Hypertransport,
-// but respect the VCI protocol.
-// It is considered as a local interconnect that must be attached to 
-// one OR SEVERAL clusters in a global interconnect.
-// It uses two different routing table:
-// - the cmd_routing_table decodes the local field of the VCI address 
-//   to return the target port
-// - The rsp_routing_table decodes the local field of the VCI srcid 
+// but respect the VCI protocol. It can be attached to one OR SEVERAL clusters,
+// using a vci_io_bridge component.
+// It is considered as a local interconnect, for the ADDRESS or SRCID
+// decoding tables: 
+// - the CMD routing_table decodes the local field of the VCI ADDRESS 
+//   to return the local target port
+// - The RSP routing_table decodes the local field of the VCI SRCID
 //   to return the initator port 
 // It is implemented as two independant crossbars, for VCI commands and 
 // VCI responses respectively.
-// - The CMD crossbar has nb_ini input ports, and nb_tgt output ports.
+// - The CMD crossbar has nb_ini input ports, and nb_tgt output ports,
+//   including the ports to the vci_io_bridge component(s).
 // - The RSP crossbar has nb_tgt input ports, and nb_ini output ports.
+//   including the ports to the vci_io_bridge component(s).
 // For both crossbars, output ports allocation policy is round robin.
