ContainerWithRoundedWaveguideBundle
(*args, **kwargs)¶ Container with waveguide bundle (
picazzo3.container.container.ContainerWithWaveguideBundle
) which generates its waveguides from a given waveguide_template and routes and rounds the bends. You can specify a bend radius and rounding algorithm for the waveguides in the Layout view.Parameters: trace_template: optional
Template for all ports. If None, the waveguide templates of the ports will be used
auto_transition: optional
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: optional
Labels of the ports to be processed. Set to None to process all ports.
contents: PCell, optional
the contents of the container: the child cell
external_port_names: optional
Dictionary for remapping of the port names of the contents to the external ports
cell_instances: _PCellInstanceDict, optional
name: optional
The unique name of the pcell
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
bundle: locked
bundle of waveguides added to the contents, generated based on the supplied waveguides list

Views
-
Layout
¶ Parameters: angle_step: float and number > 0, optional
angle step for rounding
manhattan: optional
adds rectangular blocks in the bends to avoid as much as possible non-manhattan angles
rounding_algorithm: optional
rounding algorithm used to generate the bends. Can be circular, spline, …
view_name: str, optional
The name of the view
area_layer_on: optional
When True, the waveguide area will be covered by i3.Rectangles on all cover layers.
routes: optional
routes along which the waveguides will be generated
contents_transformation: GenericNoDistortTransform, optional
flatten_contents: optional
if True, it will insert the contents as elements in the layout, rather than as an Instance
bend_radius: float and number > 0, optional
bend radius for the auto-generated bends
grid: float and number > 0, locked
design grid. Extracted by default from TECH.METRICS.GRID
grids_per_unit: locked
Number of grid cells per design unit
units_per_grid: locked
Ratio of grid cell and design unit
unit: float and number > 0, locked
design unit. Extracted by default from TECH.METRICS.UNIT
