Constructor Detail

NodeIOC

public NodeIOC()

Constructs new node with given direction

NodeIOC

public NodeIOC(NodePort p,
               NetGlobal fillWith)

Constructs new node based on port.

Parameters:

fillWith - net to fill unused inputs with

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class Node

clone

public java.lang.Object clone()

creates new (unlinked) node with same parameters.

Returns:

duplicated node

Overrides:

clone in class Node

duplicate

public void duplicate(NodeIOC n)

duplicates parameters from n to this

Parameters:

n - node to copy data from

posX

public static int posX(int pi)

returns port's x position. Ports are arranged: {(0..X-1,0),(0..X-1,Y-1),(0,0..Y-1),(X-1,0..Y-1)}

Parameters:

pi - port index

Returns:

x position

posY

public static int posY(int pi)

Returns port's y position. Ports are arranged: {(0..X-1,0),(0..X-1,Y-1),(0,0..Y-1),(X-1,0..Y-1)}

Parameters:

pi - port index

Returns:

y position

posX

public int posX()

Returns its x position.

Returns:

x position

Overrides:

posX in class IndexedNode

posY

public int posY()

Returns its y position.

Returns:

y position

Overrides:

posY in class IndexedNode

indexOf

public static int indexOf(int x,
                          int y)

Returns index in array, based on position in matrix.

Parameters:

x - x position

y - y position

Returns:

array index

isConnectable

public boolean isConnectable(int pin,
                             int segment)

Returns:

true whether connection is possible for pin pin using wire segment segment/i>

Overrides:

isConnectable in class NodeRoutable

writeBitstream

public void writeBitstream(BitStreamWriter stream)
                    throws java.io.IOException

Writes (necessary) bistream representation of this object to stream. This method writes bitstream for unused LUT and FF.

Parameters:

stream - stream to write to

Overrides:

writeBitstream in class NodeRoutable
