Constructor & Destructor Documentation

MEANDER_SHAPE()

PNS::MEANDER_SHAPE::MEANDER_SHAPE ( MEANDER_PLACER_BASE *  aPlacer, int  aWidth, bool  aIsDual = false  )

inline

Parameters

aPlacer	the meander placer instance.
aWidth	width of the meandered line.
aIsDual	when true, the shape contains two meandered lines at a given offset (diff pairs).

Member Function Documentation

Amplitude()

int PNS::MEANDER_SHAPE::Amplitude ( ) const

inline

Returns

the amplitude of the meander shape.

BaseIndex()

int PNS::MEANDER_SHAPE::BaseIndex ( ) const

inline

Returns

auxiliary index of the segment being meandered in its original LINE.

BaselineLength()

int PNS::MEANDER_SHAPE::BaselineLength

(

)

const

Returns

length of the base segment for the meander (i.e.the minimum tuned length).

BaseSegment()

const SEG & PNS::MEANDER_SHAPE::BaseSegment ( ) const

inline

Return the base segment the meander was fitted to.

Returns

the base segment.

CLine()

const SHAPE_LINE_CHAIN & PNS::MEANDER_SHAPE::CLine ( int  aShape ) const

inline

Returns

the line chain representing the shape of the meander.

End()

VECTOR2I PNS::MEANDER_SHAPE::End ( ) const

inline

Returns

end vertex of the base segment of the meander shape.

Fit()

bool PNS::MEANDER_SHAPE::Fit	(	MEANDER_TYPE	aType,
		const SEG &	aSeg,
		const VECTOR2I &	aP,
		bool	aSide
	)

Attempt to fit a meander of a given type onto a segment, avoiding collisions with other board features.

Parameters

aType	type of meander shape.
aSeg	base segment for meandering.
aP	start point of the meander.
aSide	side of aSeg to put the meander on (true = right).

Returns

true on success.

IsDual()

bool PNS::MEANDER_SHAPE::IsDual ( ) const

inline

Returns

true if the shape represents 2 parallel lines (diff pair).

MakeArc()

void PNS::MEANDER_SHAPE::MakeArc	(	const SHAPE_ARC &	aArc1,
		const SHAPE_ARC &	aArc2 = SHAPE_ARC()
	)

Create a dummy meander shape representing an arc corner.

Allows representing existing arc tracks so they can be reconstructed after length tuning.

Parameters

aArc1	Arc shape on the 1st line.
aArc2	Arc shape on the 2nd line (if m_dual == true).

MakeCorner()

void PNS::MEANDER_SHAPE::MakeCorner	(	const VECTOR2I &	aP1,
		const VECTOR2I &	aP2 = VECTOR2I( 0, 0 )
	)

Create a dummy meander shape representing a line corner.

Used to define the starts/ends of meandered segments.

Parameters

aP1	corner point of the 1st line.
aP2	corner point of the 2nd line (if m_dual == true).

MaxTunableLength()

int PNS::MEANDER_SHAPE::MaxTunableLength

(

)

const

Returns

the length of the fitted line chain.

Resize()

void PNS::MEANDER_SHAPE::Resize

(

int

aAmpl

)

Change the amplitude of the meander shape to aAmpl and recalculates the resulting line chain.

Parameters

aAmpl

new amplitude.

SetBaselineOffset()

void PNS::MEANDER_SHAPE::SetBaselineOffset ( int  aOffset )

inline

Set the parallel offset between the base segment and the meandered line.

Used for dual meanders (diff pair) only.

Parameters

aOffset

the offset.

Settings()

const MEANDER_SETTINGS & PNS::MEANDER_SHAPE::Settings

(

)

const

Returns

the current meandering settings.

Side()

bool PNS::MEANDER_SHAPE::Side ( ) const

inline

Returns

true if the meander is to the right of its base segment.

Type()

MEANDER_TYPE PNS::MEANDER_SHAPE::Type ( ) const

inline

Returns

the type of the meander.

Width()

int PNS::MEANDER_SHAPE::Width ( ) const

inline

Returns

width of the meandered line.
