When preparing for a business or personal trip, most of us want to check our travel routes in advance. There are many route-planning tools on the web today, and they help us to anticipate route difficulties such as heavy traffic, changes in street names, road sizes, accident locations, and many more. Some of these map applications even tell us what time we need to leave our starting location to reach our destination on time. Many of us end up “virtually” driving the route several times before we take the actual drive. Those virtual drives help us get from point A to point B in the shortest time possible, without unpleasant surprises.
Antenna system developers often face a similar challenge: We may have a great antenna design to get an RF signal from point A to point B in isolation, but the scattering environment around the antenna directly impacts the antenna’s ability to get the job done. So how do we anticipate the different routes that the signal might be forced to take to reach its destination? You guessed it—modeling and simulation of the antenna’s interaction with that environment. Continue reading →
Today, after a video call with my kids at home, I feel more relaxed. Usually on long distance business travel, we are always concerned about the family at home. A few years ago long distance voice calls were not only costly but also of poor voice quality. Now, equipped with mobile phones, we can make high-quality audio/video calls and exchange text messages with people around the globe, at little or no cost.
It’s amazing to see the way communication technology has grown over the years. Technologies that seemed like fiction a few years ago, are now becoming reality. These include virtual reality, 3-D hologram and printing, language translation, and mobile streaming audio and video. Continue reading →
Working for ANSYS gives me incredible opportunities to work with innovative companies and learn about the latest technologies that are being developed to improve our lives. One of the intriguing companies I have had the pleasure to work with is RF2ANTENNA. RF2ANTENNA works on developing innovative and easy-to-integrate products for specific applications in wireless communications and wireless charging, with the goal of improving the efficiency of IoT devices with affordable solutions. Their core competency is in providing solutions to radiation problems in mobile products. The ANSYS Startup Program has given them the opportunity to take their work to the next level.

Amphenol® RF engineers spend countless hours working with our customers to ensure our connectors are as effectively integrated as possible to their products. With competitive pressure and new product development cycles shrinking ever more, efficient collaboration with customers and partners for successful product integration has never been more important. A critical challenge in high performance RF connector design is to understand the impact of the connector’s launch to the device. Being able to validate our connector design on the customer’s product as early and as confidently as possible in the design stage is critical. To help address this need, Amphenol® RF is now making available, for download, encrypted ANSYS HFSS 3D models. Continue reading →
Semiconductors touch every aspect of our lives — from the computers that we work on to the automobiles we drive to the medical devices that keep us healthy. As these amazing chips become smaller and more packed with functionality (the latest NVIDIA graphics chip has 21 billion transistors!), designing and producing them becomes far more complicated. Yet increased demand for smaller, more powerful integrated circuits is increasing so companies can create the products of the future. Continue reading →
NVIDIA recently announced its ultra high-end Quadro GP100 graphics card in February. Comparing to previous generations of Quadro cards, the new card runs much faster and is more power efficient. The new GP100 GPU has 3,584 CUDA cores, which deliver 10.6 and 5.3 teraflops floating point performances for single- and double-precision, respectively.
The GPU is also equipped with 16 GB HBM2 (the 2nd generation high-bandwidth memory) which allows data to be transferred at a lightning fast speed of 720 GB/sec. Both factors enhance the performance for running the most demanding transient electromagnetic simulation.
As digital electronic devices continue to shrink and put greater functionality within consumer and enterprise products, thermal management continues to grow as the bottle neck for defining next generation architectures. Significant challenges exist today because the heat being generated continues to rise while the thermal envelope remains constant for silicon devices.
While some switching power converters have moved to III-V semiconductor materials such as GaN, the overall system still contains many silicon semiconductor devices that must meet traditional thermal envelopes. The removal of this heat has become a critical aspect of the design process, often being a very significant driver of what can be delivered within an electronic product. Continue reading →
As you can imagine, there are many conversations at ANSYS centered around the simulation industry and current engineering trends. Sometimes during the conversations with my colleagues that handle the microwave and RF communication and signal and power integrity sectors of our business, I get the feeling that electromechanical design and power electronics is boring. Why do we want to talk about simulation of devices that have been around for a century like electric motors and transformers? Continue reading →
Engineers are challenged to design modern electronic systems that operate at higher speeds with lower power with ever greater functionality in an ever shrinking footprint. These design challenges drive engineers to perform Chip-Package-System (CPS) co-design and analysis. However, the design flow is often unconnected, and design data is exchanged manually leading to slow design times and error prone design methodologies. ANSYS 18 breaks down the barriers between simulation domains and delivers a Chip-Package-System workflow that enables engineers to accomplish their work in a rapid and convenient way.

ANSYS HFSS users are constantly telling me, “Wow, I didn’t know HFSS could do that!” I guess I shouldn’t be surprised — our software development and product management teams have been working tirelessly over the last few years to integrate ever more valuable features into HFSS to deliver a product worthy of its well-deserved reputation as “the gold standard.” Focusing on automated simulation and design workflows for antennas and high speed electronics, ANSYS HFSS 18 will help you achieve the increasing requirements for wireless connectivity, thermal performance and power efficiency within shorter design schedules.
