}

Definition routing tracks as a grid of equally spaced lines.

Fields

is_horizontal: bool

Direction of the track. Can be horizontal when ‘Y’ is defined in DEF (true) or vertical with ‘X’ in DEF (false).

start: Coord

Distance of the track line to the origin. For horizontal tracks this is the vertical offset (y coordinate), for vertical tracks this is the horizontal offset (y coordinate).

num_tracks: u32

Number of tracks for the grid. Must be larger than 0.

step: Coord

Spacing between tracks.

mask: Option<(MaskNum, bool)>

An optional tuple ( mask number, SAMEMASK ). mask number: Mask of the first track as used for double or triple patterning. Usually the mask is cycled for all subsequent tracks. SAMEMASK: Use the same mask number for all tracks.

layers: Vec<String>

Routing layers to be used for this track. Possibly more than one.

Trait Implementations

impl Clone for Tracks

fn clone(&self) -> Tracks

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tracks

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

Formats the value using the given formatter.

impl Default for Tracks

fn default() -> Tracks

Returns the “default value” for a type.
