Introduction

Process Design Kit (PDK) based design concept

If you already know about Process Design Kits (PDKs) in general, please skip to the section Getting started.

A PDK helps to bridge the gap between the fab or foundry offering IC technology and the designer who creates an IC design in that technology, as shown by Figure 1. In order to create a design, the designer needs to have the library cells created by the fab available, as well as technology details required for custom design of components. A PDK is implemented for a specific set of software tools.

Fig. 1 Concept of a Process Design Kit (PDK)

Luceda develops such a PDK so that it can be used by the Luceda tools (Link for Siemens EDA or IPKISS).

Luceda PDK has several components:

• Technology settings that allow for custom design:

  • Layers to draw with, in accordance with the foundry’s definitions.

  • Design rules, which provide dimensional constraints for the design to be manufacturable.

  • A design rule checking (DRC) deck, checking that the designer’s mask layout adheres to the foundry’s design rules.

  • A technology description that allows to generate 2D and 3D models that can be sent to physical simulation tools such as for FDTD or mode propagation.

  • Routing settings for optical waveguides and electrical wiring

• The fab’s cell library, providing validated building blocks to the designer:

  • Layout models that allow to place and connect the cells in the layout. These can be ‘black-box’: the detailed layout may not be visible, only the optical and electrical I/O and the bounding box.

  • Simulation models that allow for simulation and functional verification of a circuit based on these cells.

• Parametric cells for typical complex cells or repetitive tasks that a designer would like to do

• Examples and (this) manual to get started

The combination of Luceda’s design software and the Luceda PDK for CORNERSTONE is what enables the designer to create a design specific for the CORNERSTONE technology.

Note

In this text, the words cell, component and building block are used interchangeably. In the context of a PDK, a cell, building block or component usually delivers a specific unit function, such as a fiber coupler, splitter or phase modulator. There could also be more complex cells in the PDK library though. In the context of the user design, cell could mean any design or hierarchical part thereof.

Use case: PDK cell library based design

The Luceda PDK for CORNERSTONE provides a library with a number of predefined cells for the C band (1550nm) and O band (1310nm). With this library available from IPKISS, the designer can create a circuit directly in code (IPKISS) or from the L-Edit GUI using drag-and-drop of devices from the library (IPKISS Link for Siemens EDA). After placing the PDK cells, optical waveguides can be drawn in a manual or semi-automated fashion. In addition, the PDK provides the necessary settings to use picazzo, Luceda’s pcell template library with functions like ring resonators, MMIs, modulators, Mach-Zehnder interferometers, fanouts, and many more.

This approach allows for fast prototyping of designs using the CORNERSTONE technology.

Use case: Custom cell design

In a lot of cases, the user will want to design custom components and include them in the design. IPKISS provides several functions for that purpose:

• Parametric cells can be defined fully in Python script, with their parameters (properties in IPKISS), layout and simulation model.

• Basic building blocks can be virtually fabricated and sent to electromagnetic simulation tools such as FDTD and EME. IPKISS has a built-in mode solver CAMFR and provides interfaces to CST Studio suite and other 3rd party tools.

• More complex subcircuits defined in IPKISS can be simulated using the built-in compact model solver Caphe. The designer can provide models for the basic building blocks, or generate them from simulation or measurement data.

• The designer can maintain the resulting parametric cells in a library and use them from the IPKISS Link for Siemens EDA environment or in an IPKISS python code design.

Use case: Using internal and 3rd party libraries

In a larger design team or in the case of consecutive design projects, a designer or a design team will typically build up their own library of subcircuits that perform specific reusable functions. Using Luceda’s software, the designer or design team can create such proprietary libraries that work together with the Luceda PDK for CORNERSTONE. These re-usable libraries can then be shared within the team, outside of the company or used in consecutive projects.

The designer can in this way embed and sustain design knowledge in a library, and base a new design both on the PDK as well as these internal libraries.

One step further, a designer can also acquire 3rd party libraries and use them in a design project in the same way.

Fig. 2 Designing with reuseable design libraries and a PDK.

Technology settings

The PDK contains layer definitions and virtual fabrication settings for the 220nm, 340nm and 500nm SOI processes. Refer to the CORNERSTONE design rule manual and MPW call documents for detailed information.

Selecting the target technology

One PDK is used to target all the technologies. At the start of an Ipkiss script, you must import the library corresponding to the technology variant you need.

For example, the 220nm SOI process:

import cornerstone_soi220.all as cornerstone

This sets the virtual fabrication process of the 220nm SOI process and imports only the process specific components and the generic pcells.

Table 1 List of processes

Process	Library	Specific cells prefix
220nm SOI	cornerstone_soi220	SOI220nm
340nm SOI	cornerstone_soi340	SOI340nm
500nm SOI	cornerstone_soi500	SOI500nm

Layers

The following table gives an overview of the available layers and how they are named in Ipkiss. See the CORNERSTONE design rules manual for further information about the layers defined by CORNERSTONE.

Components

Which components are available to use from the Luceda PDK for CORNERSTONE?

The Luceda PDK for CORNERSTONE contains a number of predefined components that have been tested by the fab, as well as predefined waveguide templates. In addition, Luceda has provided a number of parametric cells to make life of a designer easier.

Users can use these components and mix them with their own custom designed components to create larger circuits.

How to use Luceda PDK for CORNERSTONE components?

An example of how to instantiate (or place) PDK components in IPKISS, you may refer the sample located at:

<path_to_installed_PDK>\cornerstone\docs\examples\scripts\example_components.py

For 340nm SOI, refer to the example at <path_to_installed_PDK>\cornerstone\examples\scripts\example_components_soi340.py

With IPKISS, you may execute the sample Python code.

If you use IPKISS Link for Siemens EDA, you will be able to use your mouse to drag-and-drop the components in L-Edit.

Waveguide template components

Waveguide trace templates are used to define how the connecting waveguides between the devices should be like. It contains the technology information on the layers and geometrical drawing of a specific type of waveguide, such as wire or rib waveguides.

Using the waveguide trace template, when users define the waveguide type at a device port and the connection line with another device, the waveguide will be generated with the corresponding waveguide type at the port it connects to. There are also devices that are drawn using the waveguide template as a layout parameter. It is useful in this case to change the device design by updating the waveguide template.

Two waveguide templates are predefined in the PDK: StripWaveguideTemplate, for strip waveguides fully etched to the BOX, and RibWaveguideTemplate for rib waveguides with a thin SOI slab remaining. Both have a default width of 400nm for O band and 450nm for C band.

These templates have no models yet.

Luceda picazzo components

Besides the component library provided by the foundry, users are also able to use the component templates from IPKISS’ Picazzo library.

Note

Unlike the Luceda PDK for CORNERSTONE components of which device performance is characterized and guaranteed by the fab, the Picazzo library components are up to the user to ensure compatibility with the design rules and the designed device manufacturability and performance.

The list of Picazzo library components and their documentation can be found in the IPKISS manual: https://docs.lucedaphotonics.com/picazzo/

In the documentation examples, we use the silicon_photonics as the technology library (a demo technology library from IPKISS). Now that we have a real-world PDK, we are able to use it as the technology library for the picazzo design.

Photonic crystals

Picazzo offers a lot of components for drawing photonic crystals: https://docs.lucedaphotonics.com/picazzo/phc/ These however need some customization in order to work with CORNERSTONE: the SOI slab area needs to be explicitly added.

For 220nm SOI, an example is in <path_to_installed_PDK>\docs\examples\scripts\example_phc_soi220.py.

For 340nm SOI, an example is in <path_to_installed_PDK>\docs\examples\scripts\example_phc_soi340.py

For 500nm SOI, an example is in <path_to_installed_PDK>\docs\examples\scripts\example_phc_soi500.py

How to customize a component design?

Users can also choose start a component design from scratch, instead of starting from a CORNERSTONE library component or picazzo library component.

An example is given in <path_to_installed_PDK>\docs\examples\scripts\example_customcell.py.
