Class TileRectangle

Object

com.xilinx.rapidwright.design.TileRectangle

Direct Known Subclasses:

RelocatableTileRectangle, SimpleTileRectangle

public abstract class TileRectangle
extends Object

A Rectangle of tiles, i.e. a Bounding Box around some Set of Tiles. The tiles at the edge of the rectangle (e.g. at minX/minY and maxX/maxY) are all assumed to be inside the rectangle. For both X and Y: min <= Tiles <= max The way to store tiles is set by subclasses. Depending on the storage method, they may or may not be relocatable

Method Detail

getMinRow

public abstract int getMinRow()

getMaxRow

public abstract int getMaxRow()

getMinColumn

public abstract int getMinColumn()

getMaxColumn

public abstract int getMaxColumn()

isEmpty

public abstract boolean isEmpty()

extendTo

public abstract void extendTo(Tile tile)

isInside

public boolean isInside(Tile tile)

Check whether a tile is contained in the Rectangle

Parameters:

tile - the tile to check

Returns:

true if it is inside

hpwl

public int hpwl()

overlaps

public boolean overlaps(TileRectangle other)

Check whether this Rectangle has any Tiles in common with another one

Parameters:

other - Rectangle to check

Returns:

true if there is any overlap

getWidth

public int getWidth()

getHeight

public int getHeight()

extendToCorresponding

public abstract void extendToCorresponding(RelocatableTileRectangle rect,
                                           Site currentAnchor,
                                           SiteInst templateAnchor)

Extend the Rectangle so that a shifted rectangle is inside. The Rectangle is assumed to be located relative to some anchor. The anchor is shifted from templateAnchor to currentAnchor. This location relative to the new anchor is then included in the Rectangle.

Parameters:

rect - Rectangle to include after shifting

currentAnchor - target anchor

templateAnchor - source anchor

extendToCorresponding

public void extendToCorresponding(Tile tile,
                                  Site currentAnchor,
                                  SiteInst templateAnchor)

Extend the Rectangle so that a shifted tile is inside. The Tile is assumed to be located relative to some anchor. The anchor is shifted from templateAnchor to currentAnchor. This location relative to the new anchor is then included in the Rectangle.

Parameters:

tile - tile to include after shifting

currentAnchor - target anchor

templateAnchor - source anchor

extendTo

public abstract void extendTo(RelocatableTileRectangle rect)

Extend the Rectangle so that the specified Rectangle is inside

Parameters:

rect - The Rectangle to include

getCenter

public Tile getCenter(Device device)
