ContainerWithRoundedWaveguides

class picazzo3.container.container_waveguides.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: 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

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

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
