public class Channel
extends java.lang.Object

Class that represents horizontal or vertical channel.

Channel connect two adjacent switch boxes.

Each channel is attached to node (share same source position) and consists of multiple wire segments. nets Net array identifies which of them are still free.

Nodes are adjacent when there exist wire segment between them.

List of all nodes channel connects to can be constructed.

See Also:: adjacentChannels

Field Summary
`Channel[]`	`adjacentChannels` List of all adjacent channels.
`float`	`cost` Used by wave algorithm - cost to this node
`Net[]`	`nets` Nets going through this channel, each allocating one wire segment.
`int`	`nNets` Number of nets allocated on this channel.
`Node`	`node` Node channel is connected to.
`int`	`x` This channel position.
`int`	`y` This channel position.

Constructor Summary
`Channel(int x, int y)` Constructs new channel.

Method Summary
`int`	`maxSegments()` Returns max. segments per way
`static int`	`switchsTo(int segment, int channel)` Identifies which segment we will reach, if we are on segment segment and going to neighbour index channel.

Field Detail

x

public int x

This channel position.

y

public int y

This channel position.

node

public Node node

Node channel is connected to.

adjacentChannels

public Channel[] adjacentChannels

List of all adjacent channels.

cost

public float cost

Used by wave algorithm - cost to this node

nets

public Net[] nets

Nets going through this channel, each allocating one wire segment.

nNets

public int nNets

Constructor Detail

Channel

public Channel(int x,
               int y)

Constructs new channel.

Parameters:: idx - channel position

Method Detail

maxSegments

public int maxSegments()

Returns max. segments per way

Returns:: number of used segments

switchsTo

public static final int switchsTo(int segment,
                                  int channel)

Identifies which segment we will reach, if we are on segment segment and going to neighbour index channel. This transform is based on USM.

Parameters:: segment - segment we are on; channel - index of neighbour
Returns:: neighbours segment, negative if invalid move
