Detailed Description

Track elements for fixed wires.

A TrackFixedSegment is a segment that cannot be moved from the track. It can be associated to a true blockage Segment (recognised by the fact that their owner net is the blockage net), or to a segment from an ordinary net but which is locked into position. In the latter case, the owned net may reuse this portion of the track if it needs it.

In all cases, the blockage ratio of the GCells underneath the segment are updated.

Member Function Documentation

create()

TrackSegment * create ( Kite::Track *  track, Segment *  segment  )

static

Parameters

segment	The Hurricane Segment (blockage) to take into account.
track	A Track into which insert the TrackFixedSegment.

Returns

A TrackFixedSegment wrapped around a blockage Segment.

Public constructor to insert blockage inside a Track.

isHorizontal()

bool isHorizontal ( ) const

virtual

See also:  Katabatic::AutoSegment::isHorizontal().

Implements TrackElement.

isVertical()

bool isVertical ( ) const

virtual

See also:  Katabatic::AutoSegment::isVertical().

Implements TrackElement.

isFixed()

bool isFixed ( ) const

virtual

See also:  Katabatic::AutoSegment::isFixed().

Reimplemented from TrackElement.

getId()

unsigned long getId ( ) const

virtual

Returns

The Id of the supporting AutoSegment, if there is any. Zero otherwise.

Reimplemented from TrackElement.

getDirection()

unsigned int getDirection ( ) const

virtual

Returns

The direction of the supporting element (should match the preferred direction of the Track).

Implements TrackElement.

getNet()

Net * getNet ( ) const

virtual

Returns: The Net associated to the element (may be NULL).

Implements TrackElement.

Referenced by TrackFixedSegment::getNext(), and TrackFixedSegment::getPrevious().

getLayer()

const Layer * getLayer ( ) const

virtual

Returns: The Layer of the element (should match the one of the Track).

Implements TrackElement.

getNext()

TrackElement * getNext ( ) const

virtual

Returns: The next TrackElement, on the same track and of a different net. See also:  Track::getNext().

Reimplemented from TrackElement.

getPrevious()

TrackElement * getPrevious ( ) const

virtual

Returns: The previous TrackElement, on the same track and of a different net. See also:  Track::getPrevious().

Reimplemented from TrackElement.

getAxis()

DbU::Unit getAxis ( ) const

virtual

Returns: The axis position of the element (must be the same as the Track).

Implements TrackElement.

getFreeInterval()

Interval getFreeInterval ( ) const

virtual

Returns: The greatest free interval enclosing this element.

Reimplemented from TrackElement.
