Definition of a net and possibly its routes.

Fields

name: Option<String>

Name of the net. Must be generated for MUSTJOIN nets. ‘MUSTJOIN’ is an invalid net name.

mustjoin: Option<Mustjoin>

Net name is generated for MUSTJOIN nets.

terminals: Vec<NetTerminal>

Terminals connected to the net.

shield_nets: Vec<String>

Names of special nets that are used to shield this net. The shield nets must be defined earlier in ‘SPECIALNETS’.

xtalk_class: u16

Crosstalk class number. Default is 0 which will not be written to DEF. Should be a value from 0 to 200.

non_default_rule: Option<String>

Use another width rule than the default rule defined in the LEF WIDTH statement for the routing layer.

regular_wiring: Vec<RegularWiring>

Specify the physical wiring.

source: NetSource

Source from where the net was created.

fixed_bump: bool

Fixed bump: TBD

frequency: Option<f64>

Frequency of the net. Used as a hint for the router.

original: Option<String>

If this net results from partitioning another net, then this refers to the original net.

net_use: DEFSignalUse

Usage type of the net.

pattern: NetPattern

Desired routing pattern for the net.

est_cap: Option<f64>

Estimated wire capacitance of this net.

weight: u32

Weight of the net. Nets with high weight should be tried to keep short by routing tools. Default = 1.

properties: BTreeMap<String, PropertyValue>

Additional properties.

Trait Implementations

impl Clone for Net

fn clone(&self) -> Net

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Net

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

Formats the value using the given formatter.

impl Default for Net

Custom implementation of default because weight deviates from the default of u32.

fn default() -> Self

Returns the “default value” for a type.
