-
Installation
Step-by-step instructions to install FrugalEDA on your platform.
-
First design
Create your first superconducting circuit in minutes.
🛠️ Modules¶
FrugalEDA links a set of open-source tools into a single workflow: draw a circuit, convert it to a netlist, simulate and optimize it, then visualize the results.
-
LibrePCB
The schematic editor used to draw superconducting circuits.
-
SuperLibre — Superconductor Library
Josephson junctions, signal sources, probes, transmission lines, subcircuits and SPICE commands for LibrePCB.
-
L2SPICE
Converts LibrePCB schematics to JSIM / JoSIM netlists and back-annotates results.
-
JOINUS-D
The main application: design, simulate, analyse margins and yield, and optimize superconducting circuits.
-
Simulators — JSIM & JoSIM
Josephson-junction-aware SPICE engines for transient simulation of superconducting circuits.
-
FrugalPlot
Interactive viewer for simulation and measurement data, with trackable curves and time cursors.
-
Examples
Ready-to-run superconducting circuits shipped inside L2SPICE and JOINUS-D — open one, simulate, and take it apart.
