gdsfactory.routing.route_ports_to_side

gdsfactory.routing.route_ports_to_side(ports: dict[str, ~gdsfactory.port.Port] | list[~gdsfactory.port.Port] | ~gdsfactory.component.Component | ~gdsfactory.component_reference.ComponentReference, side: str = 'north', x: float | None = None, y: float | None = None, routing_func: ~collections.abc.Callable = <function get_route>, **kwargs) → tuple[list[Route], list[Port]]

Routes ports to a given side.

Parameters:

• ports – list/dict/Component/ComponentReference to route to a side.

• side – ‘north’, ‘south’, ‘east’ or ‘west’.

• x – position to route ports for east/west. None, uses most east/west value.

• y – position to route ports for south/north. None, uses most north/south value.

• routing_func – the routing function. By default uses get_route.

Keyword Arguments:

• radius – in um.

• separation – in um.

• routing. (extend_left, extend_right for south/north)

• routing.

Returns:

with routing elements. List of ports: of the new ports.

Return type:

List of routes
