gdsfactory.routing.route_single(component, port1, port2, cross_section=None, layer=None, bend='bend_euler', straight='straight', start_straight_length=0.0, end_straight_length=0.0, waypoints=None, steps=None, port_type=None, allow_width_mismatch=False, radius=None, route_width=None, auto_taper=True, on_error='error', layer_transitions=None)[source]#

Returns a Manhattan Route between 2 ports.

The references are straights, bends and tapers.

Parameters:

  • component (Component) – to place the route into.

  • port1 (Port) – start port.

  • port2 (Port) – end port.

  • cross_section (CrossSectionSpec | None) – spec.

  • layer (LayerSpec | None) – layer spec.

  • bend (ComponentSpec) – bend spec.

  • straight (ComponentSpec) – straight spec.

  • start_straight_length (float) – length of starting straight.

  • end_straight_length (float) – length of end straight.

  • waypoints (WayPoints | None) – optional list of points to pass through.

  • steps (Sequence[Step] | None) – optional list of steps to pass through.

  • port_type (str | None) – port type to route.

  • allow_width_mismatch (bool) – allow different port widths.

  • radius (float | None) – bend radius. If None, defaults to cross_section.radius.

  • route_width (float | None) – width of the route in um. If None, defaults to cross_section.width.

  • auto_taper (bool) – add auto tapers.

  • on_error (Literal['error'] | None) – what to do on error. If error, raises an error. If None ignores the error.

  • layer_transitions (LayerTransitions | None) – dictionary of layer transitions to use for the routing when auto_taper=True.

Return type:
