Gauss SI Pro

Stackup design and solving for transmission line impedance and loss have become critical to modern PCB design and development. Many board designers and engineers are forced to use equation-based calculators or solely rely on their PCB manufacturers to handle the stackup. Gauss SI Pro is a high-fidelity simulation and design offering that provides the extreme accuracy and ease-of-use of Avishtech’s flagship Gauss Stack and Gauss 2D products and convert stackup design and impedance computations to a simple point and click process accessible at a low cost to all. No need to search for materials and their properties!

Rapid Stackup Design

Vendor-Specific Dielectric Materials Library

With an extensive built-in vendor-specific dielectric materials library, Gauss SI Pro allows you to specify each layer of a PCB stackup within seconds. This library is fully integrated with the thermomechanical reliability and electromagnetic / signal integrity simulations, so there is no additional input required from the user.

Full Stackup Design in Minutes

With a few quick clicks, a user can design an entire stackup of arbitrary size, in minutes or less, by simply specifying the Signal, Plane, and Mixed layers of copper and specifying the dielectric prepreg and core layers, a process made trivially easy with the built-in libraries, as well as the ability to add custom materials to a user-defined custom materials library.

Predefined Copper Library

A user can also take advantage of Gauss SI Pro’s predefined copper library, which contains thicknesses and Rz roughness values for available copper ranging from 1.5 µm copper for SLP to 6 ounce heavy copper. The Rz values, which are used for the glass stop and resin starvation analysis, are those typically available for a chosen copper weight/thickness.
