class picazzo3.container.transition_ports.AutoTransitionPorts

Pcell containing another PCell with transitions on all (labeled) ports, using AutoTraceTransitionFromPort. The target trace template is defined in trace_template.

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.

transition_database: AutoTransitionDatabase

AutoTransitionDatabase in which the correct transition between the two trace templates can be looked up.

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

Transitions (of type WaveguideTransitionFromPort) attached the the ports given in port_labels. Should be in the same order as port_labels.

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


Tapering ports to a wider width:

from technologies import silicon_photonics  # noqa: F401
from picazzo3.filters.ring import RingRect180DropFilter
from picazzo3.traces.wire_wg import WireWaveguideTemplate

my_ring = RingRect180DropFilter()
from picazzo3.container.transition_ports import AutoTransitionPorts

wire_t = WireWaveguideTemplate()
wire_t.Layout(core_width=0.7, cladding_width=0.7 + 2 * 2.0)
my_ring_tapered_auto = AutoTransitionPorts(
    contents=my_ring, port_labels=["W0", "W1", "E0"], trace_template=wire_t
my_ring_tapered_auto_layout = my_ring_tapered_auto.Layout()


class Layout
transition_length: ( float and Real, number and number >= 0 ), *None allowed*

Length of the transition. Set to None to take the standard transition length.

zero_length_if_identical: ( bool, bool_, bool or int )

uses a zero-length transition if the trace templates are identical

straight_extension: ( Coord2 and number >= 0 ), *None allowed*

Tuple: straight extensions of the transitions. Set to None to take the standard straight extensions

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

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
