Current IssueAll About That Route
Most designers favor manual routing, but today's interactive autorouters may be changing designers' minds by allowing users more direct control. In this issue, our expert contributors discuss a variety of manual and autorouting strategies.
Creating the Ideal Data Package
Why is it so difficult to create the ideal data package? Many of these simple errors can be alleviated by paying attention to detail—and knowing what issues to look out for. So, this month, our experts weigh in on the best practices for creating the ideal design data package for your design.
Designing Through the Noise
Our experts discuss the constantly evolving world of RF design, including the many tradeoffs, material considerations, and design tips and techniques that designers and design engineers need to know to succeed in this high-frequency realm.

Sierra Circuits to Hold Signal Integrity & Power Integrity Workshop
July 16, 2019 | Sierra CircuitsEstimated reading time: 1 minute
Sierra Circuits will host a SI/PI workshop presented by DesignCon 2017 Engineer of the Year, Heidi Barnes, and Signal Integrity Application Scientist, Tim Wang-Lee, from Keysight Technologies on September 12-13, 2019 at Levi's Stadium in Santa Clara, California.
This intensive signal integrity and power integrity workshop provides you with the necessary skills to tackle everyday SI and PI challenges with Keysight PathWave advanced design system (ADS).
The SI session starts with the holistic approach to solve any signal integrity problems by using analysis techniques such as eye diagram, mixed-mode S-parameters, time domain reflectometry (TDR) and single pulse response. The session continues to exercise the techniques in design and exploration of single-ended and differential channels. Finally, the SI workshop concludes with EM model extraction and investigation of application and standards.
In the PI sessions, we cover the elegant flat impedance design technique and explore the cohesive ADS Power Integrity eco-system. In the process of PI eco-system simulations, you will use impedance vs. frequency data to create measured models, estimate decoupling capacitance, and debug noise ripple on a power rail.
The combination of lecture and hands-on exercises allows attendees to explore the presented topics in real-time while being mentored by an expert in the field. The hands-on approach allows you to gain confidence in your ability to apply these skills on your own, at your workplace. You will learn to design, simulate and troubleshoot most common signal integrity and power integrity related issues.

DownStream Acquisition Fits Siemens’ ‘Left-Shift’ Model
06/26/2025 | Andy Shaughnessy, I-Connect007I recently spoke to DownStream Technologies founder Joe Clark about the company’s acquisition by Siemens. We were later joined by A.J. 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?
