Detailed Description

Single track placement algorithm.

Interactively routes a track and applies shove and walk around algorithms when needed.

Member Function Documentation

◆ AbortPlacement()

bool PNS::DIFF_PAIR_PLACER::AbortPlacement ( )

overridevirtual

Reimplemented from PNS::PLACEMENT_ALGO.

◆ CommitPlacement()

bool PNS::DIFF_PAIR_PLACER::CommitPlacement ( )

overridevirtual

Reimplemented from PNS::PLACEMENT_ALGO.

◆ CurrentEnd()

const VECTOR2I & PNS::DIFF_PAIR_PLACER::CurrentEnd ( ) const

inlineoverridevirtual

Return the current end of the line being placed.

It may not be equal to the cursor position due to collisions.

Implements PNS::PLACEMENT_ALGO.

◆ CurrentLayer()

int PNS::DIFF_PAIR_PLACER::CurrentLayer ( ) const

inlineoverridevirtual

Return the layer of currently routed track.

Implements PNS::PLACEMENT_ALGO.

◆ CurrentNets()

const std::vector< int > PNS::DIFF_PAIR_PLACER::CurrentNets ( ) const

overridevirtual

Return the net code of currently routed track.

Implements PNS::PLACEMENT_ALGO.

◆ CurrentNode()

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

overridevirtual

Return the most recent world state.

Implements PNS::PLACEMENT_ALGO.

◆ FixRoute()

bool PNS::DIFF_PAIR_PLACER::FixRoute	(	const VECTOR2I &	aP,
		ITEM *	aEndItem,
		bool	aForceFinish
	)

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.

◆ FlipPosture()

void PNS::DIFF_PAIR_PLACER::FlipPosture ( )

overridevirtual

Toggle the current posture (straight/diagonal) of the trace head.

Reimplemented from PNS::PLACEMENT_ALGO.

◆ GetModifiedNets()

void PNS::DIFF_PAIR_PLACER::GetModifiedNets ( std::vector< int > & aNets ) const

overridevirtual

Function GetModifiedNets.

Returns the net codes of all currently routed trace(s)

Reimplemented from PNS::PLACEMENT_ALGO.

◆ HasPlacedAnything()

bool PNS::DIFF_PAIR_PLACER::HasPlacedAnything ( ) const

overridevirtual

Reimplemented from PNS::PLACEMENT_ALGO.

◆ IsPlacingVia()

bool PNS::DIFF_PAIR_PLACER::IsPlacingVia ( ) const

inlineoverridevirtual

Function IsPlacingVia()

Returns true if the placer is placing a via (or more vias).

Reimplemented from PNS::PLACEMENT_ALGO.

◆ Move()

bool PNS::DIFF_PAIR_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.

◆ SetLayer()

bool PNS::DIFF_PAIR_PLACER::SetLayer ( int aLayer )

overridevirtual

Set the current routing layer.

Reimplemented from PNS::PLACEMENT_ALGO.

◆ SetOrthoMode()

void PNS::DIFF_PAIR_PLACER::SetOrthoMode ( bool aOrthoMode )

overridevirtual

Function SetOrthoMode()

Forces the router to place a straight 90/45 degree trace (with the end as near to the cursor as possible) instead of a standard 135 degree two-segment bend.

Reimplemented from PNS::PLACEMENT_ALGO.

◆ Start()

bool PNS::DIFF_PAIR_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.

◆ ToggleVia()

bool PNS::DIFF_PAIR_PLACER::ToggleVia ( bool aEnabled )

overridevirtual

Enable/disable a via at the end of currently routed trace.

Reimplemented from PNS::PLACEMENT_ALGO.

◆ Traces()

const ITEM_SET PNS::DIFF_PAIR_PLACER::Traces ( )

overridevirtual

Return the complete routed line, as a single-member ITEM_SET.

Implements PNS::PLACEMENT_ALGO.

◆ UpdateSizes()

void PNS::DIFF_PAIR_PLACER::UpdateSizes ( const SIZES_SETTINGS & aSizes )

overridevirtual

Perform on-the-fly update of the width, via diameter & drill size from a settings class.

Used to dynamically change these parameters as the track is routed.

Reimplemented from PNS::PLACEMENT_ALGO.
