public class RouteNodeInfo
extends Object

Field Summary

Fields

Modifier and Type	Field and Description
short	endHalfTileXCoordinate X coordinate, in half tiles, of the INT tile half that the node ends at: twice the X coordinate of that INT tile for its west half, plus one for its east half
short	endTileYCoordinate
short	halfTileWirelength Wirelength of the node in half INT tiles: the nominal length given by its intent code and name (see RouteNodeInfo.getNominalHalfTileWirelength(com.xilinx.rapidwright.device.IntentCode, java.lang.String, com.xilinx.rapidwright.device.TileTypeEnum)), whatever the number of INT tiles it spans (which differs for U-turns at the device edge and for feedthroughs); zero for nodes other than singles, doubles, quads, longs, super long lines and UltraScale(+) INODE/BOUNCE feedthroughs.

Method Summary

Modifier and Type	Method and Description
static RouteNodeInfo	get(Node node, RouteNodeGraph routingGraph) Gets the information that a RouteNode is built out of, for a given node.
static RouteNodeType	getType(Node node, RouteNodeGraph routingGraph)
static boolean	isOnBothSides(IntentCode ic) Checks if nodes of the given intent code are not on either side of an INT tile, but between two INT tiles (on the east side of one and the west side of the next): Versal SLL inputs, outputs, and data

Field Detail

type

public final RouteNodeType type

endHalfTileXCoordinate

public final short endHalfTileXCoordinate

X coordinate, in half tiles, of the INT tile half that the node ends at: twice the X coordinate of that INT tile for its west half, plus one for its east half

endTileYCoordinate

public final short endTileYCoordinate

halfTileWirelength

public final short halfTileWirelength

Wirelength of the node in half INT tiles: the nominal length given by its intent code and name (see RouteNodeInfo.getNominalHalfTileWirelength(com.xilinx.rapidwright.device.IntentCode, java.lang.String, com.xilinx.rapidwright.device.TileTypeEnum)), whatever the number of INT tiles it spans (which differs for U-turns at the device edge and for feedthroughs); zero for nodes other than singles, doubles, quads, longs, super long lines and UltraScale(+) INODE/BOUNCE feedthroughs.

Method Detail

get

public static RouteNodeInfo get(Node node,
                                RouteNodeGraph routingGraph)

Gets the information that a RouteNode is built out of, for a given node.

Parameters:

node - Node to describe.

routingGraph - Graph the node is to be a part of, or null to describe the node on its own; the returned RouteNodeInfo.type is then null, since a type only has meaning within a graph, and the returned RouteNodeInfo.endHalfTileXCoordinate is that of the west half (other than for Versal SLL inputs, outputs and data, which are always placed on the east half; see RouteNodeInfo.isOnBothSides(IntentCode)).

Returns:

That information.

isOnBothSides

public static boolean isOnBothSides(IntentCode ic)

Checks if nodes of the given intent code are not on either side of an INT tile, but between two INT tiles (on the east side of one and the west side of the next): Versal SLL inputs, outputs, and data

Parameters:

ic - Intent code of the node in question.

Returns:

True if so.

getType

public static RouteNodeType getType(Node node,
                                    RouteNodeGraph routingGraph)
