RedHawk SC uses Ansys SeaScape Big Data Platform Designed for EDA Applications

For the past few decades, System-on-Chip (SoC) has been the gold standard for optimizing the performance and cost of electronic systems. Pulling together practically all of a smartphone’s digital and analog capabilities into a monolithic chip, the mobile application processor serves as a near-perfect example of an SoC. But… Read More

EPDA overview

The capacity and energy efficiency challenges from the growing appetite for high-speed data along with advanced applications such as LIDAR and quantum computing are driving demand for increasingly large-scale photonic integrated circuits (PIC). With an ever-increasing number of components on a single photonic chip, manual… Read More

Ansys DAC 2022

The live events I have attended thus far this year have been very good. As much as I liked the virtual events, attending in the comfort of my home or sailboat, it is great to be live and networking inside the semiconductor ecosystem, absolutely.

Ansys has been a great supporter of the Design Automation Conference but this year they … Read More

It was nice to be at a live conference again. DesignCon was held at the Santa Clara Convention Center, my favorite location, which to me there was a back to normal crowd. The sessions I attended were full and the show floor was busy. Masks and vaccinations were not required, maybe that was it. Or there was a pent-up demand to get back engaged… Read More

Webinar Series: Learn the Foundation of Computational Electromagnetics
by Matt Commens on 03-21-2022 at 10:00 am

image 2 for semiwiki blog

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 11 KingCountyAirport Scenario STK Annotated

In our previous blog installments, we examined the ingredient for modeling the potential for interference between a 5G C-band base station and an aviation radar altimeter. Using candidate emissions models for the transmitter, wideband susceptibility models for a candidate radar altimeter receiver and antenna and propagation… Read More

Fig 7 HFSS Antenna Patterns

In our previous blog installment, we introduced the components of RF interference modeling, and established models for wideband peak emissions of a 5G C-band transmitter and the wideband receiver susceptibility for a radar altimeter receiver. Here, we consider the third component: the wireless channel, which considers the… 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

Fig 1 Verizon Cov Map 5G UWB

The new 5G C-band service is now up and running in the U.S., and subscribers are finally starting to see some of the promise of 5G. The new C-band services are primarily in spectrum allocations between 3 and 4 GHz, providing the wider channel allocation bandwidths necessary to deliver significantly higher data throughput. At the… Read More

ANSYS 5G Kerfuffle

As a pilot and semiconductor professional I was a bit shocked to get an Airworthiness Directive due to the 5G rollout. Airworthiness Directives are legally enforceable regulations issued by the FAA to correct an unsafe condition in a product:

“Airworthiness Directive (AD) 2021-23-12 was issued for all fleets in December… Read More
