Current IssueSignal Integrity
If you don’t have signal integrity problems now, you will eventually. This month, our expert contributors share a variety of SI techniques that can help designers avoid ground bounce, crosstalk, parasitic issues, and much more.
Proper Floor Planning
Floor planning decisions can make or break performance, manufacturability, and timelines. This month’s contributors weigh in with their best practices for proper floor planning and specific strategies to get it right.
Showing 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.

Staying on Top of Signal Integrity Challenges
09/16/2025 | Andy Shaughnessy, Design007 MagazineOver the years, Kris Moyer has taught a variety of advanced PCB design classes, both online IPC courses and in-person classes at California State University-Sacramento, where he earned his degrees in electrical engineering. Much of his advanced curriculum focuses on signal integrity, so we asked Kris to discuss the trends he’s seeing in signal integrity today, the SI challenges facing PCB designers, and his go-to techniques for controlling or completely eliminating SI problems.

Elementary Mr. Watson: Running the Signal Gauntlet
09/11/2025 | John Watson -- Column: Elementary, Mr. WatsonIf you’ve ever run a military obstacle course, you know it’s less “fun fitness challenge” and more “how can we inflict as much pain in the shortest time possible?” You start fresh—chest out, lungs full of confidence, thinking you might even look good doing this—and 10 seconds later, you’re questioning all your life choices.
The Shaughnessy Report: Winning the Signal Integrity Battle
09/09/2025 | Andy Shaughnessy -- Column: The Shaughnessy ReportWhen I first started covering this industry in 1999, signal integrity was the hip new thing in PCB design. Conference classes on signal integrity were packed to the walls, and an SI article was guaranteed to get a lot of reads.
