qnngds 4.1.1

The QNN library for creating gds files

QNNGDS

Description

QNNGDS is a toolbox built on top of phidl for device design in the QNN group.

The package is built so that any person wanting to create a new design can do it easily and quickly. It offers various devices, circuits, and test structures used and designed in the QNN group. The package hierarchy is thought as follows:

• Design: contains classes from which a complete design can be built. The class inputs are the basic parameters of the chip. Its methods are pre-built cells and tools for distributing and managing the cells over the chip.

  • Cells: is a library of cells pre-built, that are called by the Design's classes. Each cell contains a text, border marks and an experiment (circuits, devices, or tests) connected to pads for external connection.

    • Circuits: is a library of circuits made of devices.

      • Devices: is a library of basic devices like nTron, hTron, nanowires, resistors etc...

    • Tests: is a library of test structures that help through the fabrication process and characterization.

    • Geometries: contains useful shapes/geometries that are not available in Phidl or has been adapted from it for special use cases.

    • Utilities: contains useful tools for building cells and circuits.

Below is an example of the modules used to build a design.
