I would contend there is no job quite like working as a support engineer for a simulation tool like Ansys HFSS. Such a role forces an engineer to understand technology in breadth and depth like no other because HFSS is applied to such a broad range of applications and products throughout the world. My own introduction to HFSS began … Read More

object detection

In the race to get people out of the driver’s seat, the developers of autonomous vehicles (AV) and advanced driving assistance systems (ADAS) have gone off road and into the virtual world.

Using simulation to design, train and validate the brains behind self-driving cars — the neural networks of sensors and systems that perceive… Read More

automotive radar antenna array module

So you’ve decided to buy a new car? First you need to research, compare, and test drive before you finally get to drive that shiny new car home. Engineering teams choosing their preferred electromagnetic analysis tool face similar challenges. Historically, electromagnetic problems and analysis tools were relegated to a few … Read More

spiral complex

For years, there have been rather distinct domains for the extraction of interconnect models from physical design data.

Chip designers commonly focused on RC parasitics for circuit/path delay calculations and dynamic I*R voltage drop analysis.  The annotation of extracted parasitics to a netlist model required the layout… Read More

RaptorH in Virtuoso

Electromagnetic (EM) simulations have been performed on die metal structures since the 1990s. Originally, the analysis was restricted to a single device (e.g., a spiral inductor). The number of on-die devices simulated simultaneously grew with the increasing capabilities of the computers performing the computations. This… 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

Example of a multi level board analyzed by HFSS

Ansys HFSS has been the world’s trusted gold standard for  electromagnetic analysis for many years. As chip designs get bigger and more complex many users report that they’re extremely happy with the gold standard accuracy of HFSS but wish it would run faster. Fortunately Ansys has introduced many capabilities to HFSS over the… Read More
