+Interrupts are asynchronous events that are not transported by the VCI network.
+Each interrupt line is modeled by a specific point to point, uni-directional channel.

+source ans destination modules respectively.

 == F.1) Source modeling ==
 
+The source module (named '''my_source''' in this example) must contain a member variable '''p_irq''' of type '''!IrqOutPort'''. To activate, or desactivate an interruption, the source module must use the '''irqSend()''' method, that is a member function of the '''!IrqOutPort''' class. Those interrupt packets transport both a Boolean, and a date. The '''irqSend()''' prototype is defined as follows :
+{{{
+void  irqSend( bool  val,
+            sc_time  time)
+}}}

+In the Parallel Discrete Event Simulation, the pessimistic approach suppose that any PDES can update his local time only when he knows that all messages received on the input ports have dates larger than his local time.
