createPipeline

public static PBlock createPipeline(Design d,
                                    Site startingPoint,
                                    int width,
                                    int depth,

                                    boolean route,
                                    boolean useDistanceBasedRouter)

Generates the circuit for the pipeline.

Parameters:

d - RW Design object.

startingPoint - Site for placing the first/starting flop.

width - Bit width of the bus signal.

depth - Number of cycles to pipeline the bus.

distanceX - Change in the absolute tile coordinates in the x dimension for placing the next flop.

distanceY - Change in the absolute tile coordinates in the y dimension for placing the next flop.

dir - General direction of the pipeline as either horizontal or vertical. This does not need to be modified for this routing example.

route - Boolean specifying whether to route the design or not. This does not need to be modified for this routing example.

useDistanceBasedRouter - Boolean specifying whether to use distance-based router or timing-driven router.

Returns:

findRoute

                                  SitePinInst sink,
                                  TimingModel model)

findRouteCostFunction

public static void findRouteCostFunction(int tileDx,
                                         int tileDy,

                                         SitePinInst sink)

Router cost function method.

Parameters:

tileDx - Difference between coordinates in x dimension.

tileDy - Difference between coordinates in y dimension.

model - Reference to the TimingModel created by the TimingManager.

sink - SitePinInst for the sink of the physical Net object.
