Where do those strange frequency domain “Kramers-Kronig” equations come from? They don’t seem to have any obvious intuitive basis. Looking at their time domain equivalents, however, resolves the mystery and gives us an intuitive understanding of their origin.

In this article covering next-generation USB technology, Keysight reviews IP/PHY development kits, simulation solutions, and T&M solutions that serve as the foundation for silicon and system integrators to design compliant USB4 Version 2.0 products that meet strict interoperability requirements in the vast Type-C ecosystem.

SIJ technical editor, Eric Bogatin, shares his picks for great watches or reads for this month.

Recently, Signal Integrity Journal caught up with Todd Cutler, Keysight’s VP and General Manager for Design & Test Software about product development, innovation, and the latest developments in SI/PI design.

SIJ had the opportunity to engage with Larry Williams, ANSYS director of technology, to find out his thoughts on how modeling and simulation needs have changed, how the industry has responded, and what’s next. At ANSYS, Larry Williams is responsible for the strategic direction of the company’s physics simulation products.

There was a time when the signal integrity of connections between digital ICs could be nearly ensured by following one simple rule: don’t connect more than some maximum number of input pins to any single output pin. Often the fanout limit would be around 7. No models, no simulations. Everything we needed was in the thick books of vendor datasheets that filled our shelves, the tree-killing viral precursor to AOL installation CDs. Ah, those were the days!

Ken Willis provides some background on the IBIS AMI standard and looks ahead to what’s next.

Keysight is offering a free seminar to help high-speed digital design engineers, SI and PI engineers, and design team managers, learn the skills they need to overcome signal integrity (SI) and power integrity (PI) challenges.

Keysight Technologies is offering a free workshop specifically designed for signal and power integrity engineers trying to accurately model their printed circuit boards (PCBs)—a task that is now more challenging given today’s ever increasing data rates. During the hands-on workshop, titled “Keysight EEsof EDA Simulation Tools for Signal Integrity and Power Integrity,” attendees will learn about new tools in ADS 2016 that can improve PCB simulation accuracy; in particular, the pure electromagnetic-simulation-based SIPro (Signal Integrity Professional) and PIPro (Power Integrity Professional). SIPro and PIPro provide a cohesive workflow within ADS for signal integrity and power integrity applications in high-speed digital board design.
