ContainerWithRoundedWaveguides
(*args, **kwargs)¶ Container with waveguides (
picazzo3.container.container.ContainerWithWaveguides
) which generates its waveguides from a given waveguide_template and routes. You can specify a bend radius and rounding algorithm for the waveguides in the Layout view.Parameters: trace_template: ( PCell and _WaveguideTemplate ), *None allowed*
Template for all ports, defaults to TECH.PCELLS.WG.DEFAULT.When set to None, the waveguide templates of the ports will be used.
auto_transition: ( bool, bool_, bool or int )
If True, automatically transition all ports of contents to the given trace template. If False, no transitions are applied, which might lead to a discontinuity in the waveguide. Also, if trace_template is None, no transitions are applied.
port_labels: ( List with type restriction, allowed types: <type ‘str’> ), *None allowed*
Labels of the ports to be processed. Set to None to process all ports.
contents: PCell
the contents of the container: the child cell
external_port_names:
Dictionary for remapping of the port names of the contents to the external ports
name:
The unique name of the pcell
Other Parameters: trace_templates: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>, locked
list of templates to apply to all ports
waveguides: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>, locked

Views
-
Layout
¶ Parameters: angle_step: float and number > 0
Angle step for rounding.
manhattan: ( bool, bool_, bool or int )
Adds rectangular blocks in the bends to avoid as much as possible non-manhattan angles.
view_name: str and ( Alphanumeric string or Contains _$ )
The name of the view
routes:
routes along which the waveguides will be generated
contents_transformation: GenericNoDistortTransform
flatten_contents: ( bool, bool_, bool or int )
if True, it will insert the contents as elements in the layout, rather than as an Instance
bend_radius: float and number > 0
Bend radius for the auto-generated bends.
rounding_algorithm:
Rounding algorithm used to generate the bends. Can be circular, spline, ….
