Object Snapping

The layout editor provides rapid placement of instances, shapes, vias, and groups in a fin boundary. Each of these objects are snapped to snap pattern shapes differently. For example, two snap pattern shapes drawn on the same layer-purpose pair snap to each other. Whereas, when an instance containing multiple snap pattern shapes overlaps a snap pattern shape, then the instance is snapped based on only one of the snap pattern shapes.

Object snapping includes the following:

• PR Boundary Snapping
• Snap-Pattern-to-Snap-Pattern Snapping
• Instance Snapping
• Shape Snapping
• Via Snapping
• Group Snapping

PR Boundary Snapping

When you create a PR boundary with Create Method as From Selected Set and the allowedPRBoundaryDimensions constraint is set in the technology file, the PR boundary will be a multiple of the value specified in the allowedPRBoundaryDimensions constraint.
