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.

Mentor Graphics Video: Automatically Unravel Complex FPGA Signals
December 2, 2015 | Mentor GraphicsEstimated reading time: Less than a minute
Optimizing large pin-count FPGAs is challenging. Manual optimization can take days and result in reduced quality.
This new video from Mentor Graphics shows how signal pin assignments can be automatically optimized between multiple FPGAs on the PCB while respecting pin-specific rules and constraints. Reduce the number of routing layers, minimize crossovers and overall trace lengths on the PCB, and reduce signal integrity issues for higher completion rates and shorter FPGA route times.

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.
The Signal Integrity Issue: Design007 Magazine September 2025
09/09/2025 | I-Connect007 Editorial TeamAs the saying goes, “If you don’t have signal integrity problems now, you will eventually.” This month, our experts share a variety of design techniques that can help PCB designers and design engineers achieve signal integrity.
Beyond Design: Effective Floor Planning Strategies
08/20/2025 | Barry Olney -- Column: Beyond DesignComponent placement on a printed circuit board is more involved than simply fitting parts into available space. It plays a pivotal role in determining the board’s overall manufacturability, performance, reliability, and cost. Poor placement can compromise even the most meticulously designed PCB. Effective component placement alleviates mechanical stress, promotes efficient thermal management, and helps prevent excessive heat buildup.
The Art and Science of PCB Floor Planning: A Comprehensive Guide
08/14/2025 | Cory Grunwald and Jeff Reinhold, Monsoon SolutionsPCB design is an intricate and crucial part of developing electronic products. One of the foundational stages of PCB design is floor planning, a phase where the placement of components and the flow of signals are meticulously mapped out. A good floor plan ensures that the PCB performs well, is easy to manufacture, and meets all mechanical and electrical requirements. We’ll explore the essential aspects of floor planning, from its objectives and process to the challenges that designers face.
