Electromagnetic simulation tools will almost always give a result for any problem after pressing the run button. But is the result accurate? A methodology is introduced to establish the best practices for using the Ansys 2D Extractor and HFSS tools that include recommendations for the setup conditions, balancing accuracy, and computation time. With this methodology, an error in the absolute accuracy when solving for some electrical features can be achieved to better than 0.3%.

With summer upon us, it’s time to catch up on the webinars we might have missed in the last year. Here is a viewing list of the high value video content I will be reviewing in this column over the summer.

Eric Bogatin takes a closer look at the potential consequences of the widening gap between industry demand and the supply of engineers with signal integrity design skills, and poses potential solutions to inspire future generations of signal integrity engineers.

Eric Bogatin in episode 16 as he talks with Robert Feranec, president and CEO of Fedevel Academy, to learn about the go to spot for hardware engineers to sharpen their design skills.

In part three of the Ultra-Fine Line Design Guide series, previously introduced methodology is used to explore the design space for a differential pair when the return plane is far enough away that coupling to it is negligible. Read on. 

In this article, Eric Bogatin shows you that with just six principles we can understand how an oscilloscope transforms time domain measurements into a frequency domain view.

In this series, experts extend the exploration of design space to ultra-fine line features. Read on. 

Incorporating the technique of using a quiet HIGH and quiet LOW I/O pin is a simple way of opening up a small window onto what is happening with the power rail of your die. Read on to have Eric Bogatin teach you how to implement it. 

In this article, Eric Bogatin uses the issue of power integrity to illustrate why dialog between experts is crucial.
