Detailed Description

AutoContact V-Tee (one H, two V)

AutoContact to build a vertical tee (two V, one H).

Member Function Documentation

create()

AutoContactVTee * create ( GCell *  gcell, Net *  net, const Layer *  layer  )

static

Parameters

gcell	The GCell into which create the AutoContact.
net	The Net to which this AutoContact belongs.
layer	The Layer of the AutoContact.

Returns

The created AutoContactVTee.

Create a new AutoContactVTee.

References Katabatic::CntInCreationStage, Katabatic::CntVTee, and Contact::create().

getOpposite()

AutoSegment * getOpposite ( const AutoSegment *  reference ) const

virtual

Returns: The other AutoSegment the same direction as reference, this is only meaningful on AutoContactHTee or AutoContactVTee. If there is no opposite, NULL is returned.

Implements AutoContact.

getPerpandicular()

AutoSegment * getPerpandicular ( const AutoSegment *  reference ) const

virtual

Returns: The AutoSegment in the perpandicular direction to reference, this is only meaningful on AutoContacTurn. It there is no unique perpandicular, NULL is returned.

Implements AutoContact.

getSegment()

AutoSegment * getSegment ( unsigned int  index ) const

virtual

Returns: The nth anchored AutoSegment. The index is significant:

• 0 : first horizontal (h1).
• 1 : second horizontal (h2).
• 2 : first vertical (b1).
• 3 : second vertical (b2).

Not all the indexes are filled for every AutoContact. For example Turn have h1 and b1, and HTee have h1, h2 and v1.

Implements AutoContact.

updateGeometry()

void updateGeometry ( )

virtual

Compute the new position of the AutoContact based on the AutoSegment positions. The Session mechanism ensure that all AutoSegment are set into their final positions before calling this updator.

Implements AutoContact.

References AutoContact::base(), DebugSession::close(), Katabatic::CntInvalidated, AutoContact::getNet(), AutoContact::getX(), AutoContact::getY(), AutoContact::hasBadTopology(), Go::invalidate(), AutoContact::isInvalidatedCache(), DebugSession::open(), AutoContact::setX(), and AutoContact::setY().

updateTopology()

void updateTopology ( )

virtual

Restore the topology (i.e. connexity) of the contact after any number of connected segments has changed layer (at least one, up to three).

For a detailed explanation, see AutoContactHTee::updateTopology() and sawp horizontal & vertical...

Implements AutoContact.
