Gauss SI is a high-fidelity stackup designer with integrated field solver for solving for transmission line impedance, loss, and RLGC.
Gauss SI Pro contains everything found in Gauss SI, with an additional environment for deeper signal integrity simulation, for more complex transmission line structures, working with S-Parameters and Frequency-Dependent properties, as well as Uncertainty Analysis to assess the impact of manufacturing tolerances on impedance and loss.
