Current IssueProper 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.
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.

Wild River Technology's ISI-USB4 Now Supports USB 4.0 Version 2 and DisplayPort 2.1
June 27, 2024 | Wild River TechnologyEstimated reading time: 1 minute

Wild River Technology (WRT), the leading supplier of signal integrity measurement and optimization test fixtures for high-speed channels at data rates of up to 25G announced today the availability of a new inter-symbol interference (ISI) loss modeling capability. The ISI-USB4 Advanced Loss Modeling Platform Test Card Set delivers comprehensive support for demanding 25G PAM4 designs.
The product is composed of 24 stripline differential pairs of various lengths, resulting in a 1dB resolution for 26G Nyquist frequency. The laminate system is ultra-low weave, with a similar copper roughness profile expected in practical backplanes, where WRT worked extensively with Isola for an optimized laminate system. Group delay variation and block resonance, important loss considerations for data rates exceeding 25 Gb/sec, have been eliminated with special layout techniques, a homogenous laminate system, pristine connector launch design, and the use of controlled weave dielectric material. Typical skew is less than 100 femtoseconds.
“Wild River has a specific focus to elevate signal integrity practices and methodology to address challenges in modeling interconnects and make better measurements. We solve a plethora of signal integrity issues at the most advanced data rates where our goal is to generate the perfect test/characterization vehicle,” said Al Neves, founder, and chief technologist at Wild River Technology. “We now bring all of these benefits to the most demanding PAM3 and PAM-4 applications at 25G.”
Deliverables included with the new platform include:
- Six fully assembled ISI platforms assembled with 2.92mm connectors, 100% NIST traceable TDR tested, report included
- S-parameter library, measured, tested for quality, including DC point
- A ruggedized case
- COM metrics
- Web-based product training with a Wild River Technology applications engineer, scheduled at the customer’s convenience
An optional low-skew matched cable pair bundle delivering 300 femto-second skew out to 40GHz is also available.
The complete ISI-USB4 Advanced Loss Modeling Platform is available now. Contact sales@wildrivertech.com for more information.

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.
Materials and Manufacturing for the AI Era: The Next PCB Frontier
08/08/2025 | Edy Yu, Chief Editor, ECIO, and the I-Connect007 Editorial TeamAI is pushing hardware to its limits, and the bottleneck isn’t design anymore—it’s materials. Next-generation AI servers aren’t just heavier on layer counts. They demand better materials to handle the speed, heat, and signal integrity requirements of 400G, 800G, and even 1.6T Ethernet systems. Many server motherboards are already 32–36 layers. For the next wave of 1.6T-capable boards, expect 40–50 layers, which must maintain high-frequency performance without degrading signal quality.
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.
Why I Finally Embraced Autorouting
07/03/2025 | Stephen V. Chavez, Siemens EDAHere is a common misconception held by those who don’t fully understand the PCB layout process or how to wield today’s high-level EDA tools: "All I need to do is push the autorouter button, let the computer route all the signal traces, and get the layout 100% routed. It’s a no-brainer. Anyone can do it. It should take less than a few hours.”
