ContainerWithRoundedWaveguideBundle

class picazzo3.container.container_waveguides.ContainerWithRoundedWaveguideBundle(*args, **kwargs)

Container with waveguide bundle (picazzo3.container.container_waveguides.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: ( 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: <class ‘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: str

Dictionary for remapping of the port names of the contents to the external ports

name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

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

bundle: ( PCell ), locked, *None allowed*

bundle of waveguides added to the contents, generated based on the supplied waveguides list
