 interconnect is sure that no initiator will send a packet with a timestamp lesser than the timestamp of P. This temporal
 filtering operation can be factorized, when all the connected active initiators have sent at least one message to the interconnect.
-These messages are stored in a centralized data structure. This structure stores tree information: the packet, the timestamps and the current initiator activity. After elaboration of the simulator, the activity information for each initiator is set to true. A coprocessor initiator will send a message with '''m_soclib_command''' set to '''TLMT_INACTIVE''' at the beginning of the simulation.  Therefore, when all slots of this centralized structure are
-filled with real or null messages with their associated timestamps, a temporal filtering iteration can occur. 
-
-The arbitration process must take into account the actual state of the VCI initiators: For example a DMA coprocessor that has not yet been activated
-will not send request and should not participate in the temporal filtering and arbitration process. As a general rule, each VCI initiator must define an '''active''' boolean flag,
-defining if it should participate to the arbitration. This '''active''' flag is always set to true for general purpose processors.

 There are actually two fully independent networks for VCI command packets and VCI response packets.
