1. A computerized method for graphical simulation, comprising: initiating a handshaking communication between a first entity and a second entity of a graphical model representing a dynamic system, the handshaking communication enabling the first entity and the second entity to determine availability of initialization information for initializing the first entity or the second entity prior to execution of the graphical model; sending first initialization information from the second entity to the first entity; sending second initialization information from the first entity to the second entity; configuring the first entity and the second entity with the first initialization information and the second initialization information respectively; and executing a simulation loop of the graphical model.
