In order to analyze and evaluate the existing system, computer simulations are used. Also, computer simulations have been conducted to predict the performance of a future system. The model building is required for the computer simulation. It is important to validate that the developed model represents the real system exactly. Therefore, we have developed the wormhole router model whose output is the same as the output of the real system. Our lab members have developed the 4 node wormhole router system. We have developed the simulator using DEVSim++. Through controlling the parameter of the simulator, we make the output of the simulator to agree with the output of the real system. Through the various simulation, the performance is predicted. Also, the communication bottleneck have been found. Using this validated model, we can predict the wormhole router system more than 4 node with high confidence.
