摘要：An equipment for displaying a specification of behavior of a real time systemincludes a program memory for storing a plurality of program objects for simulatingoperations of objects indicative of an arrangement of the real time system and a pluralityof graphical symbol objects for expressing operational states of the objects andrelationships between the objects in the form of a graphical symbol representation on adisplay screen. In the equipment, the plurality of program objects are linked with theplurality of symbol objects through an inter-program communication control routine.Each of the program objects, when receiving a message from the communication controlroutine, is executed for simulation operation according to the received message tothereby generate a new message to be sent to the associated program routine and anew message indicative of an object state change to be sent to one of the symbol objectscorresponding to the associated object. Each of the symbol objects, when receiving themessage from the communication control routine, is executed to change a display state

of one of symbols corresponding to the associated symbol object on the display screen.
