    1818= B) Single VCI initiator and single VCI target =

    20 Figure 1 presents a minimal system containing one single initiator, '''my_initiator''' , and one single target, '''my_target''' . In the proposed example, the '''my_initiator''' module behavior is modeled by the SC_THREAD  '''execLoop()''', that contains an infinite loop.  The call-back function '''rspReceived()''' is executed when a VCI response packet is received by the initiator module.

    24 Contrary to the initiator, the target module has a purely reactive behaviour.
     24Unlike the initiator, the target module has a purely reactive behaviour.
    2525There is no need to use a SC_THREAD : The target behaviour is entirely described by the call-back function '''cmdReceived()''',
    2626that is executed when a VCI command packet is received by the target module.

    32 In the proposed example, the initiator module is modeled by the '''my_initiator''' class. This class inherit the '''!BaseModule''' class, that is the basis for all TLM-T modules. As there is only one thread in this module, there is only one member variable '''m_time''' of type '''tlmt_time''', corresponding to the PDES process local time ('''H''' on the figure). This '''m_time''' object can be accessed through the '''getTime()''', '''addTime()''' and '''setTime()''' methods.
     32In the proposed example, the initiator module is modeled by the '''my_initiator''' class. This class inherits from the '''!BaseModule''' class, that acts as the root classe for all TLM-T modules. As there is only one thread in this module, there is only one member variable '''m_time''' of type '''tlmt_time''', corresponding to the PDES process local time ('''H''' on the figure). This '''m_time''' object can be accessed through the '''getTime()''', '''addTime()''' and '''setTime()''' methods.

    3434The '''execLoop()''' method, describing the initiator activity must be declared as a member function of the '''my_initiator''' class.
