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%.

In this article, Bert Simonovich explores how to avoid “garbage in, garbage out” with field solvers by building an understanding of the nuances of PCB fabrication processes, the interpretation manufacturers’ data sheets, and the tool’s user interface.

Who doesn’t love an easy-to-use 2D field solver to calculate the single-ended or differential impedance of PCB transmission lines? Eric Bogatin takes this one from Sierra Circuits for a test drive.
