The electromagnetism problems upon which we spent many hours laboring away on homework in college has a mathematical formulation originally developed by Maxwell, Lorentz, Gauss, Faraday and others. In their full forms, these formulas are partial differential equations that come in many versions – both differential and integral.… Read More

Fig 4 Elements of Interference Analysis

In our first blog installment, we outlined the interference concerns surrounding the coexistence of the new C-band 5G telecom service spanning the band from 3.7 to 3.98 GHz with aviation radar altimeters. Radar altimeters are essential components for safety during landing and takeoff, as they offer precise measurements from… Read More

ANSYS HFSS 3D Layout 1

In 2014, many of the customers that my team and I supported in North America were still using HFSS 3D to model boards and packages. These customers were content with that interface, able to get their models setup quickly, and were okay with the solution times because when HFSS gave them an answer, they knew it was the right answer. I … Read More

Ansys Phi Plus

Automatic adaptive meshing in HFSS is a critical component of its advanced simulation process. Guided by Maxwell’s Equations, it efficiently refines the mesh to accurately capture both the geometric and electromagnetic detail of a design. The end result is a process that guarantees accurate and reliable simulation results… Read More

ansys HFSS electric field distribution in coax to waveguide adapter

In the 155 years since James Clerk Maxwell introduced the world to Maxwell’s Equations in the “Dynamic Theory of the Electromagnetic Field” there have been some amazing breakthroughs and avenues of insight. As a young electrical engineering student, we are introduced to the set of equations describing electromagnetic waves,… Read More


HFSS Performance for “Almost Free”

HFSS Performance for “Almost Free”
by Jim DeLap on 12-11-2020 at 10:00 am

HFSS PCB

Everyday, engineers are running simulations to deliver the next generation of products to make our lives better. Everyday, they wait for those simulations to finish, wishing that they could get answers instantaneously. While waiting for those simulations or checking on the status of their runs at night, they might indulge in… Read More


Getting to EMC Compliance by Design

Getting to EMC Compliance by Design
by Bernard Murphy on 05-15-2019 at 7:00 am

At the risk of highlighting my abundant lack of expertise in the domain, I had always viewed EMC (electromagnetic compatibility) compliance and testing as one of those back-end exercises that can only be done on the real device and depends on a combination of expertise and brute-force in chip/package/module/system design (decaps,… Read More

A Synergistic Chip-Package-System Analysis Methodology
by Tom Dillinger on 12-23-2015 at 4:00 pm

Looking back, 2015 was a significant year for mergers and acquisitions in the EDA industry. The Semiwiki team maintains a chronology of major transactions here.

As I was reviewing this compendium, one of the entries that stands out is the acquisition of Apache Design Solutions by Ansys, Inc. a couple of years ago.

At that time, there… Read More

Simulating Full-System EMI for a Car in Just 28 Minutes
by Bernard Murphy on 10-23-2015 at 8:00 pm

While there’s a lot of cool technology in modern semiconductors, it’s important to raise our sights periodically to understand how well these chips will work in the systems for which they are designed. One area driving a lot of semiconductor growth is automobile electronics. We’ve had drive-train control forever it seems, but… Read More
