Keysight Technologies and ROHM Semiconductor Enable Designers to Rapidly Modify SMPS Reference Design for SiC Power Devices
“Digital Twin” of ROHM Reference Design Enables “What if…” Design Space Exploration
Keysight Technologies, Inc. (NYSE: KEYS), a leading technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world, and ROHM Semiconductor, a leading semiconductor company, jointly announce today a PathWave Advanced Design System (ADS)-compatible workspace that enables designers to perform pre-compliance testing on virtual prototypes of switched-mode power supply (SMPS) designs. This new capability saves time and cost by catching errors early in the design before they become a big problem.
Demand for SMPS is driven by the need for greater efficiency, increased power density and lower cost. Fast, low-loss switches made from silicon carbide (SiC) and related materials will power future applications due to the high performance and efficiency they enable. However, unwanted side effects from high-speed switching include voltage spikes (“ringing”). In addition, it is more difficult to meet conducted and radiated electromagnetic interference (EMI) specifications in higher speed designs. Pre-compliance analysis of a “virtual prototype” or “digital twin” is ideal for managing this challenge, but previously required expertise to build and use the necessary design information, called a “workspace.”
To address this, Keysight teamed with ROHM to create the “twin” of ROHM’s reference design (model P01SCT2080KE-EVK-001) available to mutual customers via Keysight’s web site at https://www.keysight.com/us/en/assets/3120-1476/application-notes/Virtual-Reference-Design.pdf.
Virtual prototypes are complementary to physical prototypes. Physical prototypes are the gold standard for compliance and measured characteristics, but have several drawbacks including: expensive and time consuming to design, build and measure; are vulnerable to catastrophic failure (the infamous “smoke test” that produces actual smoke); and it is hard to get a measurement probe onto interior nodes.
In contrast, virtual prototypes are easy to change and while they do flag device overstress as warning messages during simulation, they never emit real
A designer who created a set of stunning icons for popular iPhone apps has made more than $100,000 within just a week of putting them on sale.
San Francisco-based Traf stuck lucky when tech reviewer Marques Brownlee spoke about the stylish, minimalist icons in a recent show on his hugely popular YouTube channel.
Apple’s recent launch of iOS 14 allows for greater customization of the iPhone’s home screen using widgets — something Android users have been able to do for years.
While Apple still doesn’t allow an easy way to change app icons, a new workaround via the Shortcuts app also lets you swap out the regular icons with something more pleasing to the eye.
“I saw some people sharing screenshots of their iPhones after discovering that iOS 14 now allows you to add custom icons to your home screen using the Siri Shortcuts app,” Traf wrote in a blog post about his experience creating the app icons. “This was the first time you can really customize iOS, and it was catching on.”
Traf continued: “As soon as I noticed the hype, I put together some icons in my own style, downloaded some widgets, and tried it all out. I thought it looked cool, so I shared a screenshot of it on Twitter. Right away, people started asking about the icons in the screenshot.”
The sudden attention prompted him to set up an online storefront selling the pack of 120 icons for $28.
Traf said that when he woke up the next day he saw that the tweet had exploded on Twitter, with subsequent media attention helping to push sales to around $6,000 within just 48 hours.
And then, toward the end of September, Marques Brownlee got involved.
“He shared a video about all of this
As the Cooper Hewitt, Smithsonian Design Museum’s 21st National Design Awards gala kicked off Thursday evening, host Bobby Berk told a story about his own introduction to design, which paved the way for his eventual fame on “Queer Eye” and beyond. He recalled visiting a Target store, where he observed the results of the iconic collaboration between the retailer and architect Michael Graves: ordinary, affordable household projects designed to delight their users.
“Right then and there I thought to myself, I want to have a part of that,” he told the event’s audience last night. “I want to work in design and make people’s lives better through design.”
The impact of design on ordinary lives and the world around us was everywhere at the annual gala, which moved to an online format this year. In place of cocktails and fancy dresses, virtual attendees watched short films showcasing the work of the award winners.
Accepting the National Design Award for Design Visionary on behalf of crowdfunding platform Kickstarter, CEO Aziz Hasan spoke directly to all the creators thinking about launching a new venture but wondering whether—especially at this moment—it was possible.
“I want to tell each of you, you should definitely take a shot,” he said. “These ideas are what society thrives on.”
Since its start in 2009, Kickstarter has helped hundreds of thousands of new ideas get off the ground. The platform allows anyone to seek support for their project directly from the public rather than from banks or venture funds. More than 18 million people have paid over $5 billion to support innovative products, businesses and other projects through the site. In 2015, Kickstarter became a Public Benefit Corporation, reflecting its prioritization of its
