Description

This guide will break down everything you need to know about the Superconductor library for LibrePCB, from the installation to the reference guide that explains each of the schematic elements of the library.

Superconducting elements are necessary to make schematics of superconductor circuits with LibrePCB. Most of the common elements, like Josephson junctions, are present in the Superconductor library for LibrePCB. Besides Josephson junctions, the library contains various signal sources for currents, voltages and phases, as well as measurement probes, transmission lines, subcircuits and control commands that can be used for circuit time-domain simulations. All elements were designed to be compatible with the syntax of JSIM or JoSIM simulators.

Installation

Automatic

The library can easily be installed with the FrugalEDA installer available at https://gitlab.com/frugaleda. To intall the library simply verify that the checkbox “Superconductor library” is checked during the installation process so that the package is installed automatically at the right place.

Manual

The library can also be installed manually, or in case of issue during the automatic installation. To do so, the directory Superconductors.lplib, available with the L2SPICE open source code, needs to be moved inside the LibrePCB Workspace located by default in the "~/LibrePCB-Workspace/data/libraries/local" folder. By default LibrePCB Workspace is located in the user's HOME folder, if not specified otherwise during the setup process after the first launch of LibrePCB.
