With Gauss SI, you don’t need to ever build another Signal Integrity Test Vehicle! Gauss SI was built from the ground up with a high-order Finite Difference and high-order Integration computational engine, to provide the highest accuracy at very high speed. Gauss SI’s superior underlying technology results in higher accuracy than not only the lower end Boundary Element based software, but even the highest end Finite Element based software, with zero setup time, and hundreds of predefined geometries. Most importantly, because Gauss SI accounts for ground plane losses – unlike any other solution in the market today – it shows exceptional agreement between simulation and measurement for insertion loss, truly eliminating the need for insertion loss measurement of Signal Integrity Test Vehicles.
In the below two examples, we show a comparison between measured insertion loss and simulated insertion loss as reported by two well-regarded competitors, as well as by Gauss SI. These examples were run with the reported dielectric properties and copper roughness data and the dimensions of the measured traces – no fudge factors or tuning. As evidenced by the two examples, Competitor B shows very poor accuracy for insertion loss over the full domain. Competitor A, while not as poor as Competitor B, also shows poor accuracy that gets perceptibly worse with frequency. However, Gauss SI (the blue line) tracks extremely closely with the measured insertion loss, something not previously attainable with transmission line simulation, finally bridging the gap between simulation and measurement.
