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.

iCD Offers Affordable PCB Simulation and Analysis Service
October 29, 2019 | ICDEstimated reading time: 1 minute
For a limited time, iCD is cutting the cost of a comprehensive post-layout PCB analysis by 50%*. This includes signal and power integrity simulation. Barry Olney, a Design007 Magazine columnist, will personally analyze your high-speed PCB design and provide direct feedback and guidance on how to best deal with any issues that may be found.
So, if you are unsure of your next complex digital PCB design–get some help from an expert designer. This takes the pressure off you, improves your skills and your boss will be happy as the design will be completed on schedule and will perform reliably saving costly iterations.
The iCD post-layout analysis includes:
- Review of schematics to ensure correct creation of design and technology constraints.
- Analysis of the PCB substrate to ensure:
a) Impedance of single ended and differential signals meet the requirements of the technologies employed.
b) That there are clear return paths and reference planes are appropriately assigned.
c) Materials are selected to minimize cost, provide adequate performance and are stocked by the client's preferred fab shop.
- Analysis of the power distribution network to ensure minimum AC impedance is attained up to the maximum required frequency.
- Advice on the placement and routing of power planes and pours.
- Advice on critical placement and best routing strategies for the technology employed.
- Assessment of high-speed signal terminations, matched delay/lengths and impedance matching.
- Simulation of high-speed critical signals to ensure timing requirements are met.
- Batch mode simulation and interactive analysis of crosstalk.
- High-speed DRC analysis–scan for violations of signal integrity, power integrity and EMI rules.
- Estimate of electromagnetic radiation to ensure the product meets FCC/CISPR Class B requirements.
- Ensure the board is manufactureable and meets IPC standards.
- A comprehensive simulation report will be provided to the client upon completion of the project.
Please contact Barry Olney for further information and to book a time slot–opportunities are limited.
“I check all the boxes to ensure your project’s success.” --Barry Olney

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?
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.
