A single-phase simulation. Consider a “single-phase” simulation approach for the output queued switch example in Figure 24.7 where the ReadInputs and WriteOutputs functions are merged. Explain how problems in determining the order in which to evaluate nodes could arise. Are there situations in which this single-phase approach could work? Hint: Consider the topology of the network under simulation.
