Module libreda_lefdef::def_ast

Data types specific to DEF.

Structs

• Component
  Instantiation of a component in DEF.
• DEF
  Representation of a design as defined in DEF.
• DEFPropertyDefinition
  Property definition used in DEF.
• Group
  Define a group of components. Optionally restrict the component locations to a region.
• LayerBlockage
  Define a region on a layer that is blocked from being used.
• Mustjoin
  TBD
• Net
  Definition of a net and possibly its routes.
• Pin
  External pin definition in DEF. Associates an external pin name with the internal net name.
• PinPort
  Definition of the port of a pin.
• PlacementBlockage
  Define a region where placement of components is not allowed.
• Region
  Defines a physical area that can be used to place components or groups.
• RegularWiring
  Representation of regular wiring.
• RegularWiringStatement
  Wiring statement which makes up the RegularWiring.
• Row
  Definition of a standard-cell row.
• RowStepPattern
  Repetition pattern for rows.
• SpecialNet
  Definiton of a special net and possibly its routes.
• Tracks
  Definition routing tracks as a grid of equally spaced lines.
• ViaGeometry
  Geometrical shapes of a via.
• ViaMaskNum
  Mask number of a via for multi patterning.
• ViaRule
  Rule for via creation.

Enums

• Blockage
  Either a metal/via blockage or a component placement blockage..
• ComponentSource
  Source of a component.
• DEFPropertyObjectType
  Type of parent object of the property.
• DEFSignalUse
  Signal usage type of a pin in DEF.
• NetPattern
  Routing pattern of a net. Default: Steiner
• NetSource
  Source of a net.
• NetTerminal
  An internal pin or external pin of another component where a net can be attached.
• PinPortStatement
  Definition of the shapes of a pin port.
• PlacementBlockageType
  Specify the type of a soft blockage.
• RectOrPolygon
  Either a rectangle or a polygon.
• RegionType
  Type of the region. A region defines a physical are where components should be placed. Fence regions force components to be placed inside, guides are not hard constraints.
• RegularWiringElement
  Represent an element of regular (non-special) wiring.
• RoutingPoint
  ‘Vertex’ in the routing path.
• SpacingOrDesignRuleWidth
  Holds either the value of the SPACING argument or DESIGNRULEWIDTH argument of a geometrical layer as used in the LAYER definition in PIN or OBS.
• ViaDefinition
  Definition of via geometries or rules to generate a via.
• WiringClass
  Wiring class. Tells whether a wiring can be changed by tools, manually or not at all.

Type Definitions

• Coord
  Integer coordinate type.
• MaskNum
  Integer type used for mask numbers.
