-Figure 1 presents a minimal system containing one single initiator, and one single target. In the proposed example, the initiator module doesn't contains any parallelism, and can be modeled by a single SC_THREAD, describing a single PDES process. The activity of the '''my_initiator ''' module is described by the SC_THREAD '''execLoop()''', that contain an infinite loop. The variable '''m_time''' represents the PDES process local time.

The member variable '''m_time''' ('''H''' on the figure) represents the PDES process local time. The call-back function '''rspReceived()''' is executed when a VCI response packet is received by the initiator module.

-Contrary to the initiator, the target module has a purely reactive behaviour. There is no need to use a SC_THREAD to describe the target behaviour : A simple method is enough.

 The VCI communication channel is a point-to-point bi-directionnal channel, encapsulating two separated uni-directionnal channels : one to transmit the VCI command packet, one to transmit the VCI response packet.
