Description

(Virtuoso Advanced Node for Layout Standard)(Virtuoso Advanced Node for Layout Standard) Retrieves information related to snap pattern definitions from the technology database identified by techID.

Attributes

name	A list of snap pattern definition names.
layer	A list of layers on which the snap pattern definitions apply.
layerNum	A list of layer numbers corresponding to these layers.
purpose	A list of purposes on which the snap pattern definitions apply.
purposeNum	A list of purpose numbers corresponding to these purposes.
direction	A list of direction values identifying the direction in which each snap pattern track is created.
step	A list of spacing values identifying the spacing between snap pattern tracks.
snappingLayers	A list of layers on which the shapes snap to the snap pattern.
type	A list of snap pattern definition types, local or global.
offset	A list of distance values defining for each snap pattern the distance of the first snap pattern track from the bottom or the left edge of the bounding box shape.
trackWidth	A list of widths of the physical shapes that each track represents.
trackGroups	(Virtuoso Advanced Node for Layout Only) A list of groups of tracks with variable spacing.
