Path

class ipkiss3.all.Path

Layout element consisting of a closed or open Shape drawn on a given Layer with a given line width

Parameters:

line_width: required
shape: Shape, required
layer: __Layer__, required: Layout layer on which the element needs to be placed
extension: tuple2 and Tuple of <class ‘float’>, optional: extension of the path at start and end: (start, end)
absolute_line_width: ( bool, bool_ or int ), optional
path_type: List with value restriction, allowed values: [0, 1, 2, 4], optional
transformation: GenericNoDistortTransform, optional

Examples

# Shows how to use the different path types: NORMAL, ROUNDED, EXTENDED, VARIABLE
import ipkiss3.all as i3

# Define new layer
process = i3.ProcessLayer(name="process", extension="PROC")
layer = i3.PPLayer(process=process, purpose=i3.TECH.PURPOSE.DRAWING)
i3.TECH.GDSII.LAYERTABLE[(process, i3.TECH.PURPOSE.DRAWING)] = (500, 0)

# Paths with different path types
elements = i3.ElementList()
elements += i3.Path(
    layer=layer, line_width=1.0, shape=[(0.0, 0.0), (10.0, 0.0), (10.0, 10.0)], path_type=i3.PATH_TYPE.NORMAL
)

elements += i3.Path(
    layer=layer, line_width=1.0, shape=[(20.0, 0.0), (30.0, 0.0), (30.0, 10.0)], path_type=i3.PATH_TYPE.ROUNDED
)

elements += i3.Path(
    layer=layer, line_width=1.0, shape=[(40.0, 0.0), (50.0, 0.0), (50.0, 10.0)], path_type=i3.PATH_TYPE.EXTENDED
)

elements += i3.Path(
    layer=layer,
    line_width=1.0,
    shape=[(60.0, 0.0), (70.0, 0.0), (70.0, 10.0)],
    path_type=i3.PATH_TYPE.VARIABLE,
    extension=(3.0, 1.0),
)

example_path = i3.LayoutCell(name="example_path").Layout(elements=elements)
example_path.write_gdsii("example_path.gds")

set_line_width(new_line_width)

sets the line width property of the Path.

Parameters:

new_line_widthpositive number

size_info(layers=None)

Returns the SizeInfo object corresponding to the footprint of this element.

Parameters:

layers: list, optional: The layers to be included, default is None (all layers)

Returns:

SizeInfo object
