Detailed Description

AutoContact Terminal (S/T is a Terminal)

AutoContact that are directly attached by either source or target or both to a terminal.

Member Function Documentation

◆ create() [1/2]

AutoContactTerminal * create ( GCell gcell,
Component rp,
const Layer layer,
Point  point,
DbU::Unit  width,
DbU::Unit  height 
)
static
Parameters
gcellThe GCell into which create the AutoContact.
rpThe RoutingPad on which to anchor the AutoContact.
layerThe Layer of the AutoContact.
pointThe absolute position.
widthThe width of the AutoContact.
heightThe height of the AutoContact.
Returns
The created AutoContact.

Create a new AutoContactTerminal anchored on rp. point gives the absolute position.

References Hook::detach(), and Component::getBodyHook().

Referenced by GCellTopology::doRp_AccessPad(), and GCellTopology::doRp_AutoContacts().

◆ create() [2/2]

AutoContactTerminal * create ( GCell gcell,
Component rp,
const Layer layer,
const DbU::Unit  x,
const DbU::Unit  y,
const DbU::Unit  width,
const DbU::Unit  height 
)
static
Parameters
gcellThe GCell into which create the AutoContact.
rpThe Component on which to anchor the AutoContact.
layerThe Layer of the AutoContact.
xThe absolute X position.
yThe absolute Y position.
widthThe width of the AutoContact.
heightThe height of the AutoContact.
Returns
The created AutoContact.

Create a new AutoContactTerminal anchored on rp. (x,y) gives the absolute position.

The anchor component rp is most often a Hurricane::RoutingPad (occurrencing a Hurricane::Segment) or directly a Hurricane::Segment, in case of RoutingPad layer promotion.

References Katabatic::CntInCreationStage, Contact::create(), Component::getPosition(), and DbU::getValueString().

◆ getNativeConstraintBox()

Box getNativeConstraintBox ( ) const
virtual

Returns: The native constraint box (that is, whithout any user constraints applied). For AutoContactTerminal, this is the Box of the supporting external component, and for all others the bounding box of the owning GCell.

Reimplemented from AutoContact.

References AutoContact::getAnchor(), GCell::getBoundingBox(), Occurrence::getEntity(), RoutingPad::getOccurrence(), Transformation::getOrientation(), Occurrence::getPath(), Component::getPosition(), RoutingPad::getSourcePosition(), Segment::getSourcePosition(), RoutingPad::getTargetPosition(), Segment::getTargetPosition(), Path::getTransformation(), and DbU::getValueString().

◆ 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.

References AutoSegment::isHorizontal(), and AutoSegment::isVertical().

◆ 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.

◆ updateGeometry()

void updateGeometry ( )
virtual

◆ updateTopology()

void updateTopology ( )
virtual

Restore the topology (i.e. connexity) of the contact after the incident segment has changed layer.

Based on the layer depth delta between the terminal and the segment three case can occurs:

  • The delta is zero, then just sets the layer of the contact to the common metal layer.
  • The delta is one, then sets the contact layer to VIA connecting the two layers.
  • The delta is two, then create a dogleg to restore the connexity. Depending on whether the terminal was attached to the source or target, sets the layer of the segments.
  • A delta of more than two is an error, and must never occurs.

As, by default, the perpandicular is set in the layer above the parallel, it may be necessary to adjust his layer as well (to the one below).
