Current IssueShowing Some Constraint
A strong design constraint strategy carefully balances a wide range of electrical and manufacturing trade-offs. This month, we explore the key requirements, common challenges, and best practices behind building an effective constraint strategy.
All 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.

PCB Layout Rules of Thumb for Consideration
November 25, 2024 | Patrick Davis, Cadence Design SystemsEstimated reading time: 1 minute

Just 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.
While many aspects of PCB layout are governed by procedures, standards, and workflows, there is still much that belongs only to tribal knowledge. Unless this knowledge is collected, documented, and incorporated into a design database, it will only exist in the information that gets passed from one designer to the next. Let’s take a look at some of the more common PCB layout rules of thumb and see how they apply to the boards we are currently laying out.
Start with a Plan
Something that you probably won’t ever find printed in a company procedure or a PCB design tutorial is the importance of having a plan before you start. Many layout designers have been known to plunge right into a new design, without first considering all the ramifications of what they are doing. This can lead to routing frustrations and eventual changes to the placement to complete the design correctly. To avoid problems like these, give some thought to what you are trying to accomplish before you start placing parts.

Beyond Design: Refining Design Constraints
07/17/2025 | Barry Olney -- Column: Beyond DesignBefore starting any project, it is crucial to develop a thorough plan that encompasses all essential requirements. This ensures that the final product not only aligns with the design concept but is also manufacturable, reliable, and meets performance expectations. High-speed PCB design requires us to not only push technological boundaries but also consider various factors related to higher frequencies, faster transition times, and increased bandwidths during the design process.
