Trending at Freedom CAD: New Crop of Next‐Gen Designers

McCurdy: They have a huge population and they are educating an enormous number of engineers. They’re bringing these people into the design seats. The average age of the designer in China is substantially lower than it is here in the U.S.
In America, we have a whole bunch of baby boomers in front of the displays doing the designs. These are the 25‐ and 35‐year veterans of printed circuit design that started off laying tape and drafting from the industrial arts side of printed circuit design, that have adapted to the computers. The designer generation that’s coming up in China—they’re coming in as double Es.
That’s a benefit in terms of understanding electronics but they don’t have the years and years of practical experience. But hey, the clock is going to continue moving and they’re going to gain the experience over time.
Matties: I think the case could be made that they don’t have the years of habit embedded into them.
McCurdy: That is true. At Freedom CAD, we are grooming a crop of 20‐somethings. We’ve been doing that for about three or four years now. We’re bringing in small groups of high‐aptitude, good attitude, want‐to‐learn, puzzle‐solvers. But they don’t all make it.
To start them off we’ve got a training program that brings them up. We’ve developed some solid designers in just a few short years as apprentice journeyman. We put them under the wing of somebody who wants to help to guide them along. They come in with no baggage. We’re developing that next generation of designers ourselves. We’re doing it here in the United States.
Matties: What trends do you see in product design?
McCurdy: Density continues to march on and the biggest thing is high‐speed now. Controlled impedance, material choices, trace length matching; these things all come into play in so many of the designs that we do. That’s a big deal. Our designers just don’t “connect the dots”.
Another trend from the CAD tool standpoint – For so many years designers said, “I hate autorouters.” I would go to designer council meetings and I say, “Hey, with a show of hands, how many people autoroute?” Out of 65 people in the room, maybe five designers would raise their hands.
The CAD vendors such as Mentor and Cadence finally started listening and developed much different routing tools for their latest upgrades. It’s not just a matter of push the button, walk away, come back, and the board is done. They’re letting the designer have some say in how they direct the tool to provide guided routing automation.
For instance, Mentor Graphics has recently released in their latest version of Xpedition, a very interactive tool called “Sketch Router.” Cadence has similar types of solutions and I think that will change the 30‐year designer mentality of “I hate autorouting” to “Wow, this is a tool that will make me more productive with great results, saving me time and money.”
It’s good for our industry if we can level the playing field and keep from going overseas for the routing by doing it ourselves smartly with better tools.
Matties: Scott, thank you very much. I appreciate it!

Fresh PCB Concepts: PCB Design Essentials for Electric Vehicle Charging
11/27/2024 | Team NCAB -- Column: Fresh PCB ConceptsElectric vehicles (EVs), powered by electricity rather than fossil fuels, are transforming transportation and reducing environmental impacts. But what good is an EV if it can't be easily charged? In this month's column, Ramon Roche dives into the role of printed circuit boards (PCBs) in electric vehicle charging (EVC)—and the design considerations.
From Construction Work to PCB Design in Under a Year
11/27/2024 | Andy Shaughnessy, Design007 MagazineAt the Anaheim Electronics & Manufacturing Show in October, I had the opportunity to talk with some new PCB designers, including Jon Smith of Frontgrade Aethercomm. During the Anaheim show, John Watson, a PCB design instructor at Palomar College, led a panel of his past and present students, including Jon, who shared his story of switching from a construction career to PCB design in a matter of months, courtesy of Watson’s Palomar College design curriculum.
PCB Layout Rules of Thumb for Consideration
11/25/2024 | Patrick Davis, Cadence Design SystemsJust because a “rule of thumb” is usually based on experience instead of precise facts doesn’t negate its value. For instance, when I told my kids that a good rule of thumb was not to back-talk to their mother, they discovered very quickly how accurate my advice was once they crossed that line. There are a lot of rules of thumb that we rely on daily, including those that apply to PCB design.
HPC Customer Engages Sondrel for High End Chip Design
11/25/2024 | SondrelSondrel, a leading provider of ultra-complex custom chips, has announced that it has started front end, RTL design and verification work on a high-performance computing (HPC) chip project for a major new customer.
Rules of Thumb for PCB Layout
11/21/2024 | Andy Shaughnessy, I-Connect007The dictionary defines a “rule of thumb” as “a broadly accurate guide or principle, based on experience or practice rather than theory.” Rules of thumb are often the foundation of a PCB designer’s thought process when tackling a layout. Ultimately, a product spec or design guideline will provide the detailed design guidance, but rules of thumb can help to provide the general guidance that will help to streamline the layout process and avoid design or manufacturing issues.
