Choosing between layout extraction and circuit simulation.
The starting point determines the tool. If you have a physical layout, InductEx® can extract electrical parameters from its geometry and process information. If you have a circuit netlist, JoSIM®-Pro can simulate how voltages, currents and phase evolve over time.
The two tools address complementary parts of superconducting circuit design.

InductEx® and Studio
InductEx® relates physical geometry to the electrical parameters of a circuit. You define the layout, process, conductors and ports, then use Studio to inspect the model and its results.
The analysis starts with geometry and process information and produces electrical parameters and saved result files. The available calculations depend on the solver and licence.
JoSIM®-Pro simulation comparing matched and open loads on a generic transmission line.
JoSIM®-Pro
JoSIM®-Pro simulates circuits containing Josephson junctions, bias networks and transmission lines. Its source, schematic and Results views let you relate the circuit definition to switching events, signal propagation and the effect of parameter changes.
The inputs are a SPICE-style circuit and analysis settings; the outputs include time-domain voltage, current and phase.
Companion tools and their roles.
The companion tools cover different parts of the design and analysis workflow. We can help you identify the package and licence required for your work.
InductEx® Studio
The native workspace for preparing and inspecting InductEx® models, meshes and results.
InductEx-LVS™
A separate layout-versus-schematic tool for checking connectivity. This checks how the layout is connected, while parameter extraction determines its electrical values.
TetraHenry®
A field solver used with meshed extraction models. Standalone and bundled releases are listed separately.
Optimum™
A command-line companion for specification checks, parameter margins, model-based yield estimates and parameter searches. It runs separately from the JoSIM®-Pro GUI.
