Gauss SI

Tired of Inaccurate Impedance Simulation Predictions vs. Measurement?

Tired of Maintaining Libraries of Dks and/or fudge factors that still don’t match measurements?

Gauss SI is the solution!

For the first time, a highly accurate field solver for impedance and loss predictions is available.
No need for highly inaccurate online calculators/equations or very expensive (yet still inaccurate) field solvers!

Simply purchase Gauss SI for the extra special price of 5000</span> only3500 per year (for purchases made before March 31, 2024) for an individual license! Just use the link at the bottom of this page.

Gauss SI has built-in stackup design capabilities with an extensive library of materials and automatically accounts for measurement approaches and has special models (including accounting for neat resin between traces) built-in to provide very high accuracy for impedance and loss without the need for fudge factors or tuning.

Get S-Parameters, conduct Uncertainty Analysis (to account for manufacturing variability), and characterize full impedance, loss, and RLGC at the click of a button!

Full Stack Synthesis

With Gauss SI, you can perform electromagnetic Synthesis – where the trace widths are iteratively simulated for a target impedance – for every single ended and differential transmission line in your entire stackup with a single click. Within minutes, Gauss SI will search for and find trace widths that fall within your specified impedance tolerance for your entire stack – simply take a coffee break and let Gauss SI figure out your stackup’s line widths for you!

Full Stack Analysis

Similarly, Gauss SI can also perform electromagnetic Analysis for a full stackup with a single click. This analysis can be done as static to simply find static impedance values, or as frequency and roughness-dependent. The static analysis simply provides the static impedance, but the frequency-dependent analysis allows you to look at the frequency-dependent impedance, loss, and full RLGC for all of your transmission lines with a single click.

Frequency and Roughness Dependent Analysis

For the Frequency-Dependent Analysis, you simply select your intended conductor roughness model (you can choose between Hammerstad, Huray, and Causal-Huray) and specify the relevant conductor roughness parameters (RMS roughness for Hammerstad and the Surface Ratio and Sphere Radius for Huray and Causal-Huray), along with the frequency of operation, and Gauss SI will solve for the frequency-dependent impedance, dielectric, conductor & insertion loss, as well as the RLGC parameters for each single ended and differential transmission line in your stackup.
