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

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

view_name: str, optional

The name of the view

drawing purpose layer for the cladding

core_purpose: PatternPurpose, optional

drawing purpose for the waveguide core

core_layer: __Layer__, optional

layer used to define the core of the waveguide

pin_shape: Shape, optional

shape to be used for the pins

trace_template_for_ports: _TraceTemplate.Layout, optional

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

control_shape_layer: __Layer__, optional

draws the control shape on top of the waveguide

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

grids_per_unit: locked

Number of grid cells per design unit

units_per_grid: locked

Ratio of grid cell and design unit

grid: float and number > 0, locked

design grid. Extracted by default from TECH.METRICS.GRID

unit: float and number > 0, locked

design unit. Extracted by default from TECH.METRICS.UNIT
