  Reference to a shape.
• SimplePolygon
  A SimplePolygon is a polygon defined by vertices. It does not contain holes but can be self-intersecting.

Enums

• TerminalRef
  Either a pin or a pin instance.

Traits

• Area
  Calculate the area of a geometry.
• BoundingBox
  Calculation of the ‘bounding box’, i.e. the smallest rectangle that contains the geometrical object.
• DoubledOrientedArea
  Calculate the doubled oriented area of a geometry. Using the doubled area allows to compute the area without using fractions. This is especially helpful when computing in integer coordinates.
• HierarchyBase
  Most basic trait for the hierarchical flyweight pattern which is used to efficiently represent chip layouts and netlists.
• HierarchyBaseMT
  Helper trait which constrains HierarchyBase for such that ID types are Send and Sync as commonly used for parallel algorithms.
• HierarchyEdit
  Edit functions for a hierarchical flyweight structure like a netlist or a cell-based layout.
• HierarchyEditUtil
  Modifying utility functions for the cell hierarchy.. Import the this trait to use the utility functions all types that implement the HierarchyEdit trait.
• HierarchyIds
  Identifier types used for components of hierarchical netlists and layouts.
• HierarchyReferenceAccess
  Trait that provides object-like read access to a cell hierarchy structure and its elements.
• HierarchyUtil
  Non-modifying utility functions for the cell hierarchy.. Import the this trait to use the utility functions all types that implement the HierarchyBase trait.
• IdType
  Trait used for identifier types.
• IdTypeMT
  Traid used for thread-safe.
• L2NBase
  Fused layout and netlist view. This trait makes the link between netlist elements and layout elements.
• L2NBaseMT
  Helper trait which constrains L2NBase for such that ID types are Send and Sync as commonly used for parallel algorithms.
• L2NEdit
  Fused layout and netlist view. This trait makes the link between netlist elements and layout elements.
• L2NIds
  Defines ID types of a netlist and layout. Implemented automatically.
• LayoutBase
  Most basic trait of a layout.
• LayoutBaseMT
  Helper trait which constrains LayoutBase for such that ID types are Send and Sync as commonly used for parallel algorithms.
• LayoutEdit
  Trait for layouts that support editing.
• LayoutEditUtil
  Helper functions for layouts.
• LayoutIds
  Define ID types used in layouts.
• LayoutReferenceAccess
  Trait that provides object-like read access to a layout structure and its elements.
• MapPointwise
  Transform the geometrical object by transforming each point of it.
• Mirror
  Mirror at the x or y axis.
• NetlistBase
  Most basic trait for traversing a netlist. A netlist extends the HierarchyBase and hence is hierarchical. NetlistBase extends the components of the hierarchy with pins and nets. Each cell can have pins. Each cell instance has pin instances that correspond one-to-one to the pins of the template cell. Cells can contain nets. Each pin and each pin instance can be connected to one or zero nets. A net can be connected to an arbitrary number of pins and pin instances.
• NetlistBaseMT
  Helper trait which constrains NetlistBase for such that ID types are Send and Sync as commonly used for parallel algorithms.
• NetlistEdit
  Trait for netlists that support editing.
• NetlistEditUtil
  Modifying utility functions for netlists. Import the this trait to use the utility functions all types that implement the NetlistBase trait.
• NetlistIds
  Identifier types used for components of netlists.
• NetlistReferenceAccess
  Trait that provides object-like read access to a hierarchical netlist structure and its elements.
• NetlistUtil
  Non-modifying utility functions for netlists. Import the this trait to use the utility functions all types that implement the NetlistBase trait.
• RegionSearch
  Access shapes and instances in a layout based on their locations.
• RotateOrtho
  Rotate by a integer multiple of 90 degrees.
• Scale
  Scale the geometrical shape. Scaling center is the origin (0, 0).
• SimpleStdCellPlacer
  Traits for simple placement engines that care about standard-cells only and cannot handle obstructions.
• Translate
  Translate the geometrical object by a vector.
• TryBoundingBox
  Try the calculation of the ‘bounding box’, i.e. the smallest rectangle that contains the geometrical object. In some cases this is not always possible, so the try might fail. For instance a set of polygons does not have a bounding box if the set is empty.
• TryCastCoord
  This trait defines the type-casting of the coordinate types for geometrical objects.
• TryIntoBoundingBox
  Try to compute the bounding box while consuming the data. This is intended to be used for computing bounding boxes over iterators.
• WindingNumber
  Compute the winding number of a geometrical object around a point. The winding number is used to check if a point is contained in a shape.
