This article details the electromagnetic simulation of low frequencies in Ansys Electronics Desktop, focusing specifically on arbitrary length transmission lines and cables with uniform cross sections. It presents two-dimensional, quasi-static field and circuit solvers as an alternative simulation method, covering the simulation workflow while highlighting the differences and benefits of using this method as opposed to using predominant full-wave field solvers. 

Bert Simonovich explains why material anisotropy is not solely responsible for contributing to Dkeff surrounding a via hole structure. The via barrel conductor roughness and resin content of the as-fabricated dielectric pressed thicknesses must be considered and adjusted before applying this heuristic method to calculate Dkxy.

S-parameter data can reveal more than what it initially shows. This article presents four key insights that can be derived from your S-parameters, enabling smarter simulation and improving your signal integrity intuition.

While the lossless characteristics of superconducting interconnect can trigger visions of tremendous bandwidths over infinite physical distances, superconductors have unique properties that can appreciably affect signal integrity in unexpected ways. This article introduces kinetic inductance from the eyes of signal integrity with the aim of preparing engineers to analyze superconducting links.

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%.

DesignCon, the premier high-speed communications and system design conference, returns to its home at the Santa Clara Convention Center in Santa Clara, Calif., with technical paper sessions, tutorials, industry panels, product demos, and exhibits, January 30 to February 1, 2024. Group Event Director Suzanne Deffree reflects on the resources, networking, and innovation that DesignCon 2024 will bring.

This paper addresses the challenge of how to simulate the power integrity ecosystem and include the feedback loop and switching noise of a switch mode power supply (SMPS) without waiting days for the simulation results. The solution presented here uses control loop theory state space equations to create a behavioral model of an SMPS that allows for fast simulation.

Where do those strange frequency domain “Kramers-Kronig” equations come from? They don’t seem to have any obvious intuitive basis. Looking at their time domain equivalents, however, resolves the mystery and gives us an intuitive understanding of their origin.

In this article covering next-generation USB technology, Keysight reviews IP/PHY development kits, simulation solutions, and T&M solutions that serve as the foundation for silicon and system integrators to design compliant USB4 Version 2.0 products that meet strict interoperability requirements in the vast Type-C ecosystem.
