route

photonforge.parametric.route(*, port1, port2, radius=None, waypoints=(), technology=None, name='', straight_kwargs={}, bend_kwargs={}, s_bend_kwargs={}, circuit_model_kwargs={})

Route the connection between 2 compatible ports.

The route is built heuristically from straight(), bend(), and s_bend() sections, favoring Manhattan geometry.

Parameters:

  • port1 (Port) – First port to be connected.

  • port2 (Port) – Second port to be connected.

  • radius (float | None) – Radius used for bends and S bends.

  • waypoints (Sequence) – 2D coordinates used to guide the route.

  • technology (Technology) – Component technology. If None, the default technology is used.

  • name (str) – Component name.

  • straight_kwargs (dict[str, Any]) – Dictionary of keyword arguments passed to the photonforge.straight() function.

  • bend_kwargs (dict[str, Any]) – Dictionary of keyword arguments passed to the photonforge.bend() function.

  • s_bend_kwargs (dict[str, Any]) – Dictionary of keyword arguments passed to the photonforge.s_bend() function.

  • circuit_model_kwargs (dict[str, Any]) – Dictionary of keyword arguments passed to the component’s photonforge.CircuitModel.

Returns:

Component with the route, including ports and model.

Return type:

Component

Note

Each waypoint can also include the route direction at that point by including the angle (in degrees). Angles must be a multiple of 90°.
