JoSIM-Pro simulation of pulse propagation through an eight-junction circuit. The traces show the input, midpoint and output around the first propagated pulse.
A two-layer paired-spiral demonstration layout in the InductEx Studio GDSII workspace.
Simulated responses of matched and open loads on a generic 4 Ω lossless transmission line.
Simulating signals in superconducting circuits.
JoSIM-Pro models the time-domain response of circuits containing Josephson junctions, sources, transmission lines and loads. By changing the circuit parameters, you can examine switching events, signal propagation and the effect of bias and termination choices.
Engineering support for your design.
If you need help with a particular circuit or layout, we can discuss the modelling, simulation or extraction required to answer your question. Start by describing the design, the information available and what you’d like to determine.
We’ll agree the scope and expected outputs before the analysis begins.
Research, examples and product documentation.
Papers and worked examples show how the tools are used and provide a starting point for your own model. The manuals explain the corresponding installation and workflow.
