Member Function Documentation

◆ AmplitudeStep()

void PNS::MEANDER_PLACER_BASE::AmplitudeStep ( int aSign )

virtual

Increase/decreases the current meandering amplitude by one step.

Parameters

aSign direction (negative = decrease, positive = increase).

◆ CheckFit()

virtual bool PNS::MEANDER_PLACER_BASE::CheckFit ( MEANDER_SHAPE * aShape )

inlinevirtual

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

aShape the shape to check.

Returns: true if the shape fits.

Reimplemented in PNS::DP_MEANDER_PLACER, and PNS::MEANDER_PLACER.

◆ Clearance()

int PNS::MEANDER_PLACER_BASE::Clearance ( )

virtual

Return the clearance of the track(s) being length tuned.

Returns: clearance value in internal units

◆ cutTunedLine()

void PNS::MEANDER_PLACER_BASE::cutTunedLine	(	const SHAPE_LINE_CHAIN &	aOrigin,
		const VECTOR2I &	aTuneStart,
		const VECTOR2I &	aCursorPos,
		SHAPE_LINE_CHAIN &	aPre,
		SHAPE_LINE_CHAIN &	aTuned,
		SHAPE_LINE_CHAIN &	aPost
	)

protected

Extract the part of a track to be meandered, depending on the starting point and the cursor position.

Parameters

aOrigin	the original line.
aTuneStart	point where we start meandering (start click coordinates).
aCursorPos	current cursor position.
aPre	part before the beginning of meanders.
aTuned	part to be meandered.
aPost	part after the end of meanders.

◆ lineLength()

long long int PNS::MEANDER_PLACER_BASE::lineLength ( const ITEM_SET & aLine ) const

protected

Calculate the total length of the line represented by an item set (tracks and vias)

Parameters

aLine

Returns: Pointer to world to search colliding items.

◆ MeanderSettings()

const MEANDER_SETTINGS & PNS::MEANDER_PLACER_BASE::MeanderSettings ( ) const

virtual

Return the current meandering configuration.

Returns: the settings

◆ SpacingStep()

void PNS::MEANDER_PLACER_BASE::SpacingStep ( int aSign )

virtual

Increase/decrease the current meandering spacing by one step.

Parameters

aSign direction (negative = decrease, positive = increase).

◆ TuningInfo()

virtual const wxString PNS::MEANDER_PLACER_BASE::TuningInfo ( EDA_UNITS aUnits ) const

pure virtual

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

Implemented in PNS::DP_MEANDER_PLACER, PNS::MEANDER_PLACER, and PNS::MEANDER_SKEW_PLACER.

◆ TuningStatus()

virtual TUNING_STATUS PNS::MEANDER_PLACER_BASE::TuningStatus ( ) const

pure virtual

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

Implemented in PNS::DP_MEANDER_PLACER, and PNS::MEANDER_PLACER.
