Parameters

layer	the layer of the gauge (has to be of metal type).
direction	the preferred routing direction.
type	is it a pin only layer.
depth	the depth (position) of the gauge.
density	the track density (0.0 < d < 1.0).
offset	position of the first track.
pitch	distance, center-to-center between tracks.
wireWidth	width to use to draw routing wire.
viaWidth	side length to use for VIAs. Returns: The new layer gauge.

destroy()

divide()

void CRL::RoutingLayerGauge::divide	(	DbU::Unit	dividend,
		long &	quotient,
		long &	modulo
	)		const

Parameters

dividend	the length into witch put tracks.
quotient	the number of tracks that fits the interval.
modulo	the remainder.

getTrackNumber()

unsigned int CRL::RoutingLayerGauge::getTrackNumber	(	DbU::Unit	start,
		DbU::Unit	stop
	)		const

Returns: the number of tracks that can tool place in the interval [start:stop].

		DbU::Unit	stop,
		DbU::Unit	position,
		unsigned	mode
	)		const

Returns: the index of the track nearest position position in interval [start:stop], according the rounding mode.
