Detailed Description

Differential Pair length-matching/meandering tool.

Member Function Documentation

◆ AbortPlacement()

bool PNS::DP_MEANDER_PLACER::AbortPlacement ( )
overridevirtual

Reimplemented from PNS::PLACEMENT_ALGO.

◆ CheckFit()

bool PNS::DP_MEANDER_PLACER::CheckFit ( MEANDER_SHAPE aShape)
overridevirtual

Checks if it's OK to place the shape aShape (i.e.

if it doesn't cause DRC violations or collide with other meanders).

Parameters
aShapethe shape to check.
Returns
true if the shape fits.

Reimplemented from PNS::MEANDER_PLACER_BASE.

◆ CommitPlacement()

bool PNS::DP_MEANDER_PLACER::CommitPlacement ( )
overridevirtual

Reimplemented from PNS::PLACEMENT_ALGO.

◆ CurrentEnd()

const VECTOR2I & PNS::DP_MEANDER_PLACER::CurrentEnd ( ) const
overridevirtual

Function CurrentEnd()

Returns the current end of the line(s) being placed/tuned. It may not be equal to the cursor position due to collisions.

Implements PNS::PLACEMENT_ALGO.

◆ CurrentLayer()

int PNS::DP_MEANDER_PLACER::CurrentLayer ( ) const
overridevirtual

Function CurrentLayer()

Returns the layer of currently routed track.

Implements PNS::PLACEMENT_ALGO.

◆ CurrentNets()

const std::vector< int > PNS::DP_MEANDER_PLACER::CurrentNets ( ) const
overridevirtual

Function CurrentNets()

Returns the net code(s) of currently routed track(s).

Implements PNS::PLACEMENT_ALGO.

◆ CurrentNode()

NODE * PNS::DP_MEANDER_PLACER::CurrentNode ( bool  aLoopsRemoved = false) const
overridevirtual

Return the most recent world state.

Implements PNS::PLACEMENT_ALGO.

◆ FixRoute()

bool PNS::DP_MEANDER_PLACER::FixRoute ( const VECTOR2I aP,
ITEM aEndItem,
bool  aForceFinish = false 
)
overridevirtual

Commit the currently routed track to the parent node, taking aP as the final end point and aEndItem as the final anchor (if provided).

Returns
true if route has been committed. May return false if the routing result is violating design rules. In such cases, the track is only committed if Settings.CanViolateDRC() is on.

Implements PNS::PLACEMENT_ALGO.

◆ HasPlacedAnything()

bool PNS::DP_MEANDER_PLACER::HasPlacedAnything ( ) const
overridevirtual

Reimplemented from PNS::PLACEMENT_ALGO.

◆ Move()

bool PNS::DP_MEANDER_PLACER::Move ( const VECTOR2I aP,
ITEM aEndItem 
)
overridevirtual

Move the end of the currently routed trace to the point aP, taking aEndItem as anchor (if not NULL).

Implements PNS::PLACEMENT_ALGO.

◆ Start()

bool PNS::DP_MEANDER_PLACER::Start ( const VECTOR2I aP,
ITEM aStartItem 
)
overridevirtual

Start routing a single track at point aP, taking item aStartItem as anchor (unless NULL).

Implements PNS::PLACEMENT_ALGO.

◆ Traces()

const ITEM_SET PNS::DP_MEANDER_PLACER::Traces ( )
overridevirtual

Function Traces()

Returns all routed/tuned traces.

Implements PNS::PLACEMENT_ALGO.

◆ TuningInfo()

const wxString PNS::DP_MEANDER_PLACER::TuningInfo ( EDA_UNITS  aUnits) const
overridevirtual

Return a string describing the status and length of the tuned traces.

Implements PNS::MEANDER_PLACER_BASE.

◆ TuningStatus()

DP_MEANDER_PLACER::TUNING_STATUS PNS::DP_MEANDER_PLACER::TuningStatus ( ) const
overridevirtual

Return the tuning status (too short, too long, etc.) of the trace(s) being tuned.

Implements PNS::MEANDER_PLACER_BASE.
