    55This hardware component is a generic micro-network respecting the

    7 network for VCU commands and VCI responses, and supports several
    8 simultaneous transaction.

    2626This component has two "structural" parameters, that can be used to fit
    2727the behaviour of a specific physical micro-network:
    28  * The !MinLatency parameter is a number of cycles that defines the latency of an empty network.
    29  * The !FifoDepth parameter can be increased to improve the saturation threshold.
     28 * The MIN_LATENCY parameter is a number of cycles that defines the latency of an empty network.
     29 * The FIFO_DEPTH parameter can be increased to improve the saturation threshold.
