Representation of a design as defined in DEF.

Fields

version: Option<String>

Version of the DEF syntax.

busbitchars: (char, char)

Characters that are used to mark bus bit indices. Default are [ and ].

dividerchar: char

Character used as path separator. Default is /.

design_name: Option<String>

Name of the design.

technology: Option<String>

Name of the technology.

units: u32

Distance units per micron. Values supported by LEF are: 100, 200, 1000, 2000, 10000, 20000 The database unit value in LEF must be greater or equal to the one in DEF to avoid round-off errors.

history: Vec<String>

Arbitrary text.

property_definitions: BTreeMap<String, DEFPropertyDefinition>

Definitions of custom properties used in the design.

die_area: Option<SimpleRPolygon<Coord>>

Shape of the die.

rows: BTreeMap<String, Row>

Rows stored by their name.

tracks: Vec<Tracks>

Routing grid for standard-cell based designs.

gcell_grid: Vec<()>

TODO

vias: BTreeMap<String, ViaDefinition>

Geometry definitions of the vias used in the design.

styles: Vec<()>

Styles of wire ends.

nondefault_rules: ()

TODO

regions: BTreeMap<String, Region>

Regions are named geometrical locations that can be used to place components.

components: Vec<Component>

Components of the design. This includes placed and unplaced cells and macros.

pins: Vec<Pin>

Definitions of external pins of the design. Associates external pin names with internal nets and pin geometries.

pin_properties: ()

Definitions of pin properties. TODO

blockages: Vec<Blockage>

Placement and routing blockages.

slots: ()

TODO

fills: ()

TODO

special_nets: BTreeMap<String, ()>

Definitions of special nets. Special nets include nets like include power, clock, RF, and analog signals. They should not be touched by the signal router.

nets: Vec<Net>

Definitions of normal signal nets.

scan_chains: ()

Scan-chain definitions.

groups: BTreeMap<String, Vec<Group>>

Groups of components.

extensions: ()

BEGINEXT blocks with non-standard extensions of the DEF format.

Implementations

impl DEF

pub fn load<R: Read>( config: &DEFReaderConfig, reader: &mut R ) -> Result<DEF, LefDefParseError>

Deserialize a DEF from a Write trait object.

pub fn load_file( config: &DEFReaderConfig, path: impl AsRef<Path> ) -> Result<DEF, LefDefParseError>

Shortcut for reading a LEF library from a file.

pub fn store_file(&self, path: impl AsRef<Path>) -> Result<(), DEFWriterError>

Shortcut for writing a LEF library to a file.

pub fn store<W: Write>(&self, writer: &mut W) -> Result<(), DEFWriterError>

Serialize to a Write trait object.

Trait Implementations

impl Clone for DEF

fn clone(&self) -> DEF

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DEF

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DEF

fn default() -> Self
