Die assembly#

With gdsfactory you can easily go from a simple Component, to a Component with many components inside.

In the same way that you need to Layout for DRC (Design Rule Check) clean devices, you have to layout obeying the Design for Test (DFT) and Design for Packaging rules.

Design for test#

To measure your chips after fabrication you need to decide your test configurations. This includes Design For Testing Rules like:

  • Individual input and output fibers versus fiber array. You can use add_fiber_array for easier testing and higher throughput, or add_fiber_single for the flexibility of single fibers.

  • Fiber array pitch (127um or 250um) if using a fiber array.

  • Pad pitch for DC and RF high speed probes (100, 125, 150, 200um). Probe configuration (GSG, GS …)

  • Test layout for DC, RF and optical fibers.

Pack#

Lets start with a resistance sweep, where you change the resistance width to measure sheet resistance.

def add_resistance_sweep_info(c):
    c.info["doe"] = "resistance_sweep"
    c.info["analysis"] = "[iv_resistance]"
    c.info["analysis_parameters"] = "[{}]"
    c.info["ports_electrical"] = 2
    c.info["ports_optical"] = 0
    return c


sweep = [gf.components.resistance_sheet(width=width) for width in [1, 10, 50]]
sweep_with_info = [add_resistance_sweep_info(c) for c in sweep]
m = gf.pack(sweep_with_info)
c = m[0]
c.draw_ports()
c.pprint_ports()
c.plot()

Then we add spirals with different lengths to measure waveguide propagation loss. You can use both fiber array or single fiber.

    """Returns spiral with Grating Couplers."""
    c = gf.components.spiral(**kwargs)

You can also add some physical labels that will be fabricated. For example you can add prefix S at the north-center of each spiral using text_rectangular which is DRC clean and anchored on nc (north-center)

text_metal = partial(gf.components.text_rectangular_multi_layer, layers=("M1",))

m = gf.pack(sweep, text=text_metal, text_anchors=("cw",), text_prefix="s")
c = m[0]
c.show()

Grid#

You can also pack components with a constant spacing.

g = gf.grid(sweep)
g.plot()

You can also add text labels to each element of the sweep

gh_ymin = gf.grid_with_text(
    sweep, shape=(len(sweep), 1), align_x="xmax", text=text_metal
)
gh_ymin.plot()

You have 2 ways of defining a mask:

  1. in YAML

  2. in Python

YAML Component#

You can also define your Component in YAML format thanks to gdsfactory.read.from_yaml

You need to define:

  • instances

  • placements

  • routes (optional)

and you can leverage:

  1. pack_doe

  2. pack_doe_grid

pack_doe places components as compact as possible.

Automated testing and analysis#

This is useful when you have a lot of components and you want to automate the testing process.

There are two main ways to define which components are testable:

  1. Include a doe (Design of Experiments) field in the component.info dictionary, as well as all relevant test and analysis information.

  2. Include a GDS label in all component test points. There are many ways to define test points, but the most common is to use a GDS label with the format <elec/opt>-<number_of_ports>-<cell_name>. This way you can easily extract all test points from the GDS file.

Automated testing with labels#

The GDS info is stored in the GDS file metadata and can be lost if the GDS file is modified with other tools that are not aware of the metadata. To avoid this, GDSFactory also supports a more traditional way of defining test points, using GDS labels.

For example, lets say you want to label the rightmost port of a component with a GDS label port_type-number_of_ports-cell_name. You can do this with the following code:

import gdsfactory as gf
from gdsfactory.typings import LayerSpec, PortsOrList

layer_label = "TEXT"


def label_farthest_right_port(
    component: gf.Component, ports: PortsOrList, layer: LayerSpec, text: str
) -> gf.Component:
    """Adds a label to the right of the farthest right port in a given component.

    Args:
        component: The component to which the label is added.
        ports: A list of ports to evaluate for positioning the label.
        layer: The layer on which the label will be added.
        text: The text to display in the label.
    """
    rightmost_port = max(ports, key=lambda port: port.dx)

    component.add_label(
        text=text,
        position=rightmost_port.dcenter,
        layer=layer,
    )
    return component
