Schematic Cells¶
This notebook demonstrates how to use kfactory for schematic-driven
photonic design. We will:
- Build higher-level schematic cells
- Create basic parametric cells (PCell) such as straights and bends
- Define routing strategies
- Compare schematic vs. extracted layouts (LVS)
- Generate reusable code from schematics

Basic example with routing¶
In order to avoid name conflicts, let's create a new clean KCLayout (our PDK container).
A PDK (Process Design Kit) defines the available layers, devices, and design rules
for a given process. Here we’ll create a lightweight one for demonstration.

WG: kf.kdb.LayerInfo = kf.kdb.LayerInfo(1, 0)
WGEX: kf.kdb.LayerInfo = kf.kdb.LayerInfo(2,0)

pdk = kf.KCLayout("SCHEMA_PDK_ROUTING", infos=Layers)

WGEX: kf.kdb.LayerInfo = kf.kdb.LayerInfo(2,0)
layers = Layers()
pdk = kf.KCLayout("SCHEMA_PDK_ROUTING", infos=Layers)
Cell functions¶
To begin, we define the basic building blocks for routing:
- A straight waveguide of given length and width
- A 90° Euler bend for turning corners
These primitives are enough to assemble larger routed networks.

def straight(width: int, length: int) -> kf.KCell:

def straight(width: int, length: int) -> kf.KCell:

return c
bend90_function = kf.factories.euler.bend_euler_factory(kcl=pdk)
bend90 = bend90_function(width=0.500, radius=10, layer=layers.WG)
Routing strategy¶
Next we define a routing strategy (route_bundle).
This specifies how to connect groups of ports with straight sections and bends.
- It ensures separation between parallel routes
- Reuses our basic cells (
straight,bend90) - Can be applied consistently across designs

Example schematic with routing¶
Now we can demonstrate usage in a schematic:
- Two straight sections (
s1ands2) - Positioned apart vertically
- Connected automatically by our routing strategy
This shows how schematics carry both connectivity and layout placement information.

Example: 45 Degrees Crossing with virtual cells¶
We’ll now construct a more advanced schematic: a grid of 45° crossings. This introduces:
- Direct polygon construction
- Use of virtual parametric cells (
vcellandVKCell) - Hierarchical design through schematic instantiation
Setup pdk¶
Let’s define a new KCLayout for this example, including
a cross-section definition for a wide waveguide.

[(LAYER.WGEX, 3000)], name="WG", main_layer=LAYER.WG

PDK Cells¶
The cross cell builds a single 45° crossing:
- Constructs polygons for waveguide arms
- Ensures spacing rules are met via
fix_spacing_tiled - Adds enclosures for cladding / fill excludes
- Creates ports in four directions for connectivity

Virtual cells¶
Unlike physical cells, virtual cells are defined parametrically:
- Only generate geometry when needed
- Lightweight and efficient
Here we define:
bend_euler: a parametric Euler bendeuler_term: a bend tapering to a terminationstraight: a parametric straight section

Crossing schematic¶
The crossing45 schematic builds an array of crossings:
- Tiles multiple
crossinstances - Adds spacers and bends to enforce pitch
- Places input/output ports systematically
This results in a scalable crossing matrix driven entirely by schematic logic.

Sample LVS of schematic vs extracted (Connection) Netlist¶
With both schematic and extracted netlists, we can perform a partial Layout vs. Schematic (LVS):
schematic_netlist: direct from schematic definitionextracted_netlist: derived from the physical layout
Matching them ensures the layout faithfully implements the intended connectivity.

Let’s make an LVS check, i.e. compare the extracted netlist versus the netlist directly from the schematic.

Converting a Schematic to a cell function (parametric cell (PCell))¶
Another powerful feature: exporting schematics as code.
code_str()generates a self-contained Python function- The result is a reusable parametric cell (PCell)
- This makes schematics portable and automatable across environments

return schematic
To avoid name conflicts with our existing schematic, let’s make a copy and rename it before execution.
In [16]:
Copied!
new_schematic = c.schematic.model_copy()
new_schematic.name = new_schematic.name + "_copy"
new_schematic = c.schematic.model_copy()
new_schematic.name = new_schematic.name + "_copy"
Executing generated code¶
We can directly execute the generated code string in this notebook, which defines a new PCell function. This closes the loop:
- Design a schematic
- Generate its layout and netlist
- Export as reusable code
In [17]:
Copied!
get_ipython().run_cell(new_schematic.code_str())
get_ipython().run_cell(new_schematic.code_str())
Out[17]:
<ExecutionResult object at 7f25a511d940, execution_count=None error_before_exec=None error_in_exec=None info=<ExecutionInfo object at 7f25a511d640, raw_cell="import kfactory as kf kcl = kf.kcls["DEFAULT"] .." transformed_cell="import kfactory as kf kcl = kf.kcls["DEFAULT"] .." store_history=False silent=False shell_futures=True cell_id=None> result=None>
Now we can instantiate the newly generated PCell and visualize it.
