gdsfactory.routing.route_ports_to_side

gdsfactory.routing.route_ports_to_side(component: Component, cross_section: CrossSectionSpec, ports: Ports | Sequence[Port] | InstancePorts | None = None, side: Literal['north', 'east', 'south', 'west'] = 'north', x: float | None = None, y: float | None = None) → tuple[list[ManhattanRoute], list[Port]]

Routes ports to a given side.

Parameters:

• component – component to route.

• cross_section – cross_section to use for routing.

• ports – ports 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.

• kwargs – additional arguments to pass to the routing function.

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
