Gauss SI
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 
3500 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.

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!
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.
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.
