ContainerWithWaveguides

class picazzo3.container.container_waveguides.ContainerWithWaveguides

Abstract base class for containers which add waveguides to the contents, such as fanout or for routing ports in certain directions

Waveguides are provided as a list of child cells. They will be bundled if bundled=True.

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.

waveguides: List with type restriction, allowed types: <class ‘ipkiss3.pcell.cell.pcell.PCell’>

waveguides added to the contents

auto_transition: ( 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.

external_port_names: str

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

contents: PCell

the contents of the container: the child cell

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

Views

class Layout

Parameters:

routes:

routes along which the waveguides will be generated

contents_transformation: GenericNoDistortTransform

transformation to apply to the contents

flatten_contents: ( bool, bool_ or int )

if True, it will insert the contents as elements in the layout, rather than as an Instance

view_name: String that contains only alphanumeric characters from the ASCII set or contains _$. ASCII set is extended on PY3.

The name of the view
