Views

class Layout

Parameters:

strip_cladding_purpose: PatternPurpose

drawing purpose for the strip wire cladding

strip_purpose: PatternPurpose

drawing purpose for the strip wire

strip_process: ProcessLayer

process for the strip wire

strip_width: float and number > 0

width of the deep-etched strip wire

cladding_width: float and number > 0

total width of the waveguide with cladding

cladding_purpose: PatternPurpose

drawing purpose layer for the cladding

cladding_process: ProcessLayer

process for the waveguide cladding, defaults to the core process

core_purpose: PatternPurpose

drawing purpose for the waveguide core

core_process: ProcessLayer

process for the shallow-etched core

windows: List with type restriction, allowed types: <class ‘ipkiss3.pcell.trace.window.window._TraceWindow’>

List of Trace Windows that know how to draw themselves relative to the shape of the Trace

core_width: float and number > 0

width of the shallow-etched core

core_layer: __Layer__

layer used to define the core of the waveguide

pin_shape: Shape

shape to be used for the pins

trace_template_for_ports: _TraceTemplate.Layout

Trace template to be used for the ports. Default = this template

width: float and Real, number and number >= 0

control_shape_layer: __Layer__

layer on which the control shape is drawn

draw_control_shape: ( bool, bool_ or int )

draws the control shape on top of the waveguide

cover_layers: List with type restriction, allowed types: <class ‘ipkiss.primitives.layer.Layer’>

layers that can be used to generate additional coverage of the trace (e.g. manhattan corners)

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
