Low-cost high-fidelity software helps democratize stackup design and simulation. At DesignCon Booth 913, Avishtech will present PCB industry expert, Lee Ritchey, who will offer mini tech sessions on the critical factors of stackup design.

SAN JOSE, Calif. — (BUSINESS WIRE) — January 25, 2023 — Avishtech, the leading provider of PCB simulation solutions, today announced the launch of two new low-cost toolsets, Gauss SI and SI Pro, that provide a clear and easy-to-use pathway to rapidly construct PCB stackups and simulate for impedance and loss with a few quick clicks. Both tools are lower-priced with Gauss SI Pro being slightly higher priced given its deeper S-Parameters, Frequency-Dependent Properties and Uncertainty Analysis capabilities.

Keshav Amla, Founder and CEO of Avishtech notes, “While Avishtech’s primary purpose with our flagship Gauss Stack software is providing a fully integrated solution that allows Computational Prototyping for reliability, manufacturability, and signal integrity, at a fundamental level, designing a stackup from a library of materials and simulating for signal integrity is almost as critical as the layout. Up until now, even these capabilities were only available to large corporations, who could afford very expensive software, such as our Gauss Stack or some other offerings in the market. However, we feel that every board designer and engineer should have the ability to specify their stackup and design for impedance and signal integrity and that’s why we’ve launched this new offering.”

Emphasizing the importance of addressing the stackup design process for today’s high data rate, high frequency designs, at DesignCon 2/1-2/2, Avishtech will feature leading PCB industry expert, Lee Ritchey in its booth (913). Ritchey notes, “Starting with traditional stack-up design, the primary concern was getting the impedance right and having enough layers to hold the signals. So, most engineers put the burden of getting the impedance calculation right on the fab shop. Hidden from view was that the fab shop engineer dealt with all of the manufacturing issues. With modern board design there are several other issues that must be accounted for including path loss, skew and very complex power delivery engineering. None of these are fab engineers capable of dealing with. As a result, the SI engineer has to take charge of the stackup design. Now, the SI engineer has to be the one responsible for manufacturability issues such as resin starvation, via reliability, glass stop, etc. This is what Avishtech’s Gauss Stack addresses.”

For the foregoing reasons as well as several other appurtenant ones, Gauss SI and Gauss SI Pro have a lot of built-in intelligence to make the stackup process easier, more accurate and better optimized. Ritchey explains, “Unfortunately, stackup design as a discipline within the product development process is not taught in most universities. As a result, product developers can be intimidated by the task just because they have not had a lot of experience with it. They learn stackup through ‘on-the-job’ experiences and, along the way, they understandably tend to make mistakes. With today’s high-speed products there is very little room for errors or inaccuracies so ‘what if’ analyses becomes a critical part of the process and that process is not always readily understood. Avishtech’s toolsets are easy to use and provide a level of predictability and reliability that is not available with any other solutions being offered today.”

Key features and benefits of Gauss SI and Gauss SI Pro include:

• An extensive, built-in dielectric materials library that enables product developers to specify each layer of a PCB stackup within seconds.
• Static or frequency-dependent Impedance and loss analysis and synthesis for all transmission lines with a single click.

Additional capabilities and features for Gauss SI Pro include:

• S-Parameters analysis, viewing, and export.
• Frequency-dependent properties analysis, viewing, and export.
• Uncertainty Analysis to account for the impact of manufacturing tolerances on impedance and loss.

About Avishtech

Avishtech is a high-technology company based in San Jose, CA. Through its software, lab, testing and consulting services, Avishtech is focused on providing critical innovations for the Printed Circuit Board industry. With its Gauss suite of PCB design and simulation products, Avishtech enables the Computational Prototyping of PCBs at the design stage, enabling previously unavailable analyses related to Signal Integrity, Manufacturability and Reliability of Printed Circuit Boards with a high degree of accuracy. Through use of the Gauss offerings, companies can bypass expensive and time-consuming prototype and test vehicle approaches that take years, instead solving problems in days or weeks. This allows product developers to go to market faster, with higher performance and higher reliability products, having spent a lot less in terms of time and development costs. In addition, Avishtech's Materials Lab and Consulting Services deliver a "deep dive" into a broad scope of materials properties and performance characteristics typically not found anywhere else. All of these capabilities and the information delivered through Avishtech's simulation offerings, services and consulting dovetail with the MBSE, models-based systems engineering design methodologies, being widely used by the industry for today's high frequency, high data rate designs.
