gdsfactory.routing.get_route(input_port: Port, output_port: Port, bend: ComponentSpec = <function bend_euler>, with_sbend: bool = False, straight: ComponentSpec = <function straight>, taper: ComponentSpec | None = None, start_straight_length: float | None = None, end_straight_length: float | None = None, min_straight_length: float = 0.01, auto_widen: bool = False, auto_widen_minimum_length: float = 100, taper_length: float = 10, width_wide: float = 2, cross_section: None | CrossSectionSpec | MultiCrossSectionAngleSpec = 'xs_sc', **kwargs) → Route[source]#

Returns a Manhattan Route between 2 ports.

The references are straights, bends and tapers. get_route is an automatic version of get_route_from_steps.

Parameters:

  • input_port – start port.

  • output_port – end port.

  • bend – bend spec.

  • with_sbend – add sbend in case there are routing errors.

  • straight – straight spec.

  • taper – taper spec.

  • start_straight_length – length of starting straight.

  • end_straight_length – length of end straight.

  • min_straight_length – min length of straight for any intermediate segment.

  • auto_widen – auto widen the straights.

  • auto_widen_minimum_length – minimum length to auto widen.

  • taper_length – length of taper.

  • width_wide – width of the wider straight.

  • cross_section – spec.

  • kwargs – cross_section settings.
