Designing without Borders – DesignCon 2016

designcon demosProduct development of today’s complex mobile and IoT devices requires the cooperation of independent design teams working at the chip, package, and system level. However, several roadblocks in the electronics design flow make this cooperation very difficult, impacting time, effort, and ultimately the cost required to deliver a successful product to market.

Santa Struggles with Radio Frequency Interference – Could Hinder Gift Delivery

Santa Calling about Radio Frequency InterferenceWhen my caller ID lit up showing an incoming call from “The North Pole” I scratched my head wondering who it could be. Only one person I know of lives at The North Pole. Yup, it was Santa. In the past, Santa has worked with ANSYS engineers to improve the structural and aerodynamic properties of his sleigh. This year, Santa had another concern that he was calling me about. It seems that on some test flights in preparation for this year’s Christmas Eve deliveries, Santa noticed that the sleigh’s on-board GPS radio that he and his elves rely on for accurate tracking information wasn’t always working properly. Santa noticed that the problem usually occurred when he flew near cell phone base station towers. We assured Santa that we could help and we set about modeling the installed radio frequency (RF) systems on his sleigh in order to understand what was happening. Continue reading

So You Want to Design Medical Devices

Healthcare is often cited as one of the leading applications for the Internet of Things (IoT). Looking around the Web, it is clear that leading high tech companies like Qualcomm, Intel, Cisco, Juniper all have initiatives on healthcare. A notable example is Google, which has already created a prototype contact lens to help measure glucose levels in diabetic patients.

“Better patient outcome” is a goal that all of us can get behind!

But even the most successful high-tech companies are quickly discovering that designing medical devices is different than designing consumer electronics. Designing for the healthcare industry requires extra rigor, insight, and collaboration with healthcare industry experts. Continue reading

I Can’t Hear You! Radio Frequency Interference (RFI) in Sports Arenas

During a recent NFL game, the visiting team complained about picking up the home team’s radio broadcast on their coach-to-coach headsets preventing the coaches from communicating with one another. The home team indicated that there were also issues communicating with the quarterback using their radio system.

RF interference stadiumsRadio frequency interference problems in major sports stadiums are unfortunately very common given the large number of radios present in a relatively small area. A typical sports stadium includes systems transmitting and receiving signals for game day operations, referee and commercial coordination, coach and player communication, a variety of cell phone networks, Wi-Fi services, and a number of other wireless services.

Making Our Highways Safer with Automotive Radar

image002Automotive radar is a key technology in delivering active safety systems that play a major role in reducing traffic fatalities. Active safety systems include adaptive cruise control and collision warning systems with automatic steering and braking intervention, lane departure warning and electronic stability control. In a collision warning system, the automotive radar consisting of a 77 GHz transmitter emits signals that are reflected from objects ahead, at the side and to the rear of the vehicle and are captured by multiple receivers integrated throughout the vehicle. The radar system can detect and track objects and trigger a driver warning of an imminent collision and initiate electronic stability control intervention.  Continue reading

Bigger, Faster Antenna and Antenna Platform Simulations!

The recent ANSYS acquisition of Delcross Technologies is a very exciting addition to our electronics product portfolio! The Internet of Things (IoT), aerospace and defense electronics, including unmanned aerial vehicles (UAVs), automotive radar and autonomous vehicles all have increasing use of multiple antennas and wireless services.

logo_delcross_2ANSYS HFSS delivers capabilities that enable antennas to be placed on complex structures followed by efficient simulation using component library models with encryption, assembly modeling with mesh assembly, and advances in our hybrid solver technology. The next logical step in HFSS development is to perform even larger platform-level simulations. To solve larger problems requires leveraging asymptotic methods of which one of the most powerful and effective method is the Shooting and Bouncing Ray (SBR) technique. The Delcross implementation of the SBR technique and its integration with high-level system analysis is the most advanced in the world and is now a part of the ANSYS product portfolio! ANSYS has fast-forwarded its development plan and will now offer our customers the ability to solve massively large antenna simulations; installed antenna performance and system RF co-site problems.

Designing a Robust Electronics Product: The Smartphone

smartphone drop testAt last year’s ANSYS Electronics Simulation Expo conference in Japan, my colleague Sandeep Sovani was delivering a keynote when he took out his Samsung smartphone and purposely dropped it on the stage! He was confidently making a point about designing robust electronic products.

The fact that a minor impact didn’t damage his phone’s exterior or degrade the performance of electronics, as best as we can tell, provides testimony that today’s engineers are paying close attention to product reliability and robustness. Continue reading

Mad About Designing a Smartwatch?

Click image to see his 2 watches in action

Jim Cramer is the host of Mad Money. I watch his high-energy, entertaining, investment show regularly. “Booyah!”. Yesterday, I was surprised to see his wrist loaded with two watches. As he didn’t explain, I can only guess as to why he was sporting his Apple Watch along with an analog timepiece. Continue reading

Automotive, the Ultimate Connected ‘Device’

The Internet of Things (IoT) is about connected devices, and those devices are not just smartphones, tablets and phablets. It is anything that can collect data (sensors), connect to the internet and transmit the data wirelessly (antennas), and make smart decisions on acquired data (embedded software / processors). The biggest “mobility device” happens to be one that is near and dear to Americans — the car. Over the last few years the amount of electronics and connectivity within a car has been rapidly growing making it a primary differentiator for an automobile. Continue reading

ANSYS 16.0 Targets Electromechanical and Power Electronic Design

Vehicle electrification, renewable energy, and power delivery applications continue to be major trends driving innovations in the industrial, automotive and aerospace sectors. “Good old designs” of power systems and electrical machines using a build-and-test methodology are out of date. Products using the old approach are filled with inefficiencies, are over-designed, and do not include electronic controls. These applications such as automotive electrification, automotive infotainment, and power electronics across many industries are driving the need for new ways of thinking and new design flows. ANSYS 16.0 delivers! Continue reading
