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.

|  | long & | modulo
| ) |  | const

Parameters

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