Struct libreda_pnr::route::airwire_router::AirWireRouter

pub struct AirWireRouter {
    air_wire_layer: u8,
    wire_thickness: SInt,
    full_mesh: bool,
}

Router that creates air wires between routing terminals in a star-topology. This does not produce a legal routing and has the only purpose to visualize the connectivity of components.

Fields

air_wire_layer: u8

Layer for the air wires.

wire_thickness: SInt

Wire thickness.

full_mesh: bool

Draw a full mesh instead of a star network.

Implementations

impl AirWireRouter

pub fn new(air_wire_layer: u8, wire_thickness: SInt, full_mesh: bool) -> Self

Create a default router.

Trait Implementations

impl SimpleRouter for AirWireRouter

fn name(&self) -> &str

Get the name of the routing engine.

fn compute_routes_impl( &self, _boundary: Rect<SInt>, net_terminals: &HashMap<usize, Vec<Vec<(SimpleRPolygon<SInt>, u8)>>>, _obstacles: &Vec<(SimpleRPolygon<SInt>, u8)> ) -> HashMap<usize, SimpleRoutedNet>

Routing algorithm implementation.

fn compute_routes( &self, boundary: Rect<SInt>, net_terminals: &HashMap<usize, Vec<Vec<(SimpleRPolygon<SInt>, u8)>>>, obstacles: &Vec<(SimpleRPolygon<SInt>, u8)> ) -> HashMap<usize, SimpleRoutedNet>

Wrapper around compute_route_impl(). Does some sanity checks before and after.

fn draw_routes<LN: L2NEdit<Coord = SInt>>( &self, chip: &mut LN, routes: HashMap<usize, SimpleRoutedNet>, routes_cell: LN::CellId, routing_layers: &Vec<LN::LayerId>, via_layers: &Vec<LN::LayerId> )

Draw the computed routes into the layout.

fn route_all_nets<LN: L2NEdit<Coord = SInt>>( &self, chip: &mut LN, top_cell: LN::CellId, routing_layers: &Vec<LN::LayerId>, via_layers: &Vec<LN::LayerId> ) -> Result<(), Vec<LN::NetId>>

Route all nets in the top_cell.

fn route_nets<LN: L2NEdit<Coord = SInt>>( &self, chip: &mut LN, top_cell: LN::CellId, routing_layers: &Vec<LN::LayerId>, via_layers: &Vec<LN::LayerId>, nets: &Vec<LN::NetId> ) -> Result<(), Vec<LN::NetId>>

Route a set of nets and creates a new cell that contains the shapes of the routes. Also outputs the routing terminal shapes to this cell (for debugging).
