    3030// This component emulates an external IO bus such as PCIe or Hypertransport,
    31 // but respect the VCI protocol.
    32 // It is considered as a local interconnect that must be attached to
    33 // one OR SEVERAL clusters in a global interconnect.
    34 // It uses two different routing table:
    35 // - the cmd_routing_table decodes the local field of the VCI address
    36 //   to return the target port
    37 // - The rsp_routing_table decodes the local field of the VCI srcid
     31// but respect the VCI protocol. It can be attached to one OR SEVERAL clusters,
     32// using a vci_io_bridge component.
     33// It is considered as a local interconnect, for the ADDRESS or SRCID
     34// decoding tables:
     35// - the CMD routing_table decodes the local field of the VCI ADDRESS
     36//   to return the local target port
     37// - The RSP routing_table decodes the local field of the VCI SRCID
    3838//   to return the initator port
    3939// It is implemented as two independant crossbars, for VCI commands and
    4040// VCI responses respectively.
    41 // - The CMD crossbar has nb_ini input ports, and nb_tgt output ports.
     41// - The CMD crossbar has nb_ini input ports, and nb_tgt output ports,
     42//   including the ports to the vci_io_bridge component(s).
    4243// - The RSP crossbar has nb_tgt input ports, and nb_ini output ports.
     44//   including the ports to the vci_io_bridge component(s).
    4345// For both crossbars, output ports allocation policy is round robin.
