If You Can Define It Right, You Can Design It Right
December 5, 2024 | Andy Shaughnessy, Design007Estimated reading time: 1 minute
Design engineer Chris Young is known for his optimized design process. As lead hardware engineer with Moog Space and Defense Group and owner of Young Engineering Services, Chris collects data like it’s going out of style, and he leaves nothing to chance.
With that in mind, I asked Chris to discuss his views on rules of thumb—which ones work, which ones should be avoided, and how rules fit ideally into the PCB design process.
Andy Shaughnessy: I know that you’ve spent a lot of time and effort over the years dialing in your design process. How do you use rules of thumb in your design cycle?
Chris Young: I use purpose-driven rules of thumb that produce practices that reduce risk and drive a desired outcome. I am much less concerned about using a specific PCB stack-up than producing a solution that works and meets requirements.
Shaughnessy: What are some of the rules of thumb that you use regularly, and why?
Young: Rule No. 1: If you can define it right, you can design it right.
Spend time up front developing requirements that can be used to guide your design to success. The lack of requirements in a project lead to technical ambiguity that is too often stop-gapped with assumptions. These assumptions lead to design errors that result in technical debt or design spins that cost money. The old adage of “measure twice, cut once” still applies. I recommend the INCOSE Guide to Writing Requirements (incose.org) for anyone interested in learning more about developing clear, actionable requirements.

Incorvaia, Siemens’ senior VP of electronic board systems. Joe discussed how he, Rick Almeida, and Ken Tepper launched the company in the months after 9/11 and how the acquisition came about. A.J. provides some background on the acquisition and explains why the companies’ tools are complementary.
Elementary Mr. Watson: Retro Routers vs. Modern Boards—The Silent Struggle on Your Screen
06/26/2025 | John Watson -- Column: Elementary, Mr. WatsonThere's a story about a young woman preparing a holiday ham. Before putting it in the pan, she cuts off the ends. When asked why, she shrugs and says, "That's how my mom always did it." She asks her mother, who gives the same answer. Eventually, the question reaches Grandma, who laughs and says, "Oh, I only cut the ends off because my pan was too small." This story is a powerful analogy for how many PCB designers approach routing today.

Cadence AI Autorouter May Transform the Landscape
06/19/2025 | Andy Shaughnessy, Design007 MagazinePatrick Davis, product management director with Cadence Design Systems, discusses advancements in autorouting technology, including AI. He emphasizes a holistic approach that enhances placement and power distribution before routing. He points out that younger engineers seem more likely to embrace autorouting, while the veteran designers are still wary of giving up too much control. Will AI help autorouters finally gain industry-wide acceptance?
Beyond Design: The Metamorphosis of the PCB Router
06/18/2025 | Barry Olney -- Column: Beyond DesignThe traditional PCB design process is often time-consuming and labor-intensive. Routing a complex PCB layout can consume up to 30% of a designer’s time, and addressing this issue is not straightforward. We have all encountered this scenario: You spend hours setting the constraints and finally hit the Go button, only to be surprised by the lack of visual appeal and the obvious flaws in the result.
