public class SimpleSimulator
extends Simulator

This class will create switch code (but not create the file) for a layout that has no overlapping routes. It does not really simulate the execution of the graph, it just dumps the switch code based the properties of the filters and joiners.

Method Detail

isSimple

public static boolean isSimple(Layout layout)

Parameters:

layout - The layout.

Returns:

True if the layout is simple (meaning no overlapping routes and no empty tiles involved in routing) and we can use the simple simulator to generate switch code.

simulate

public void simulate()

simulate in class Simulator

canFire

public boolean canFire(FlatNode node,
                       HashMap<FlatNode,Integer> executionCounts,

                         SimulationCounter counters,
                         HashMap<FlatNode,Integer> executionCounts)

Description copied from class: Simulator
