What does your layout do electrically?

Explore the electrical consequences of geometry: inductance, coupling and the process stack behind an integrated layout.

InductEx connects physical design to circuit parameters, with Studio for inspecting the model and its results.

Actual simulated load voltage for matched and open generic transmission-line terminations, showing a two-picosecond flight time.

JoSIM-Pro · Matched and open loads on a generic 4 Ω lossless line. Actual simulated responses; not measured device data.

How does your circuit respond?

See how a circuit responds over time: switching events, signal propagation, bias choices and line terminations.

JoSIM-Pro connects Josephson-junction models with the wider network of sources, interconnects and loads.
