98 I-CONNECT007 MAGAZINE I MAY 2026 The Masters of Signal Integrity ize decoupling strategies, PDN design method- ologies, and noise analysis techniques that are now standard practice in high-speed systems. Larry Smith Larry Smith contributes to this ecosystem through modeling and simula- tion methodologies that allow engineers to predict behavior before fabrication. By applying SPICE-based analysis, IBIS models, and transmission line theory, he helps engi- neers understand how interconnect structures will behave under real operating conditions. His work enables a shift from reactive debugging to predictive design validation. Mike Resso Mike Resso similarly bridges the gap between theoretical models and physical behavior through advanced measurement techniques. His work with S-parameters, de-embedding, and time-domain analysis allows engineers to extract meaningful insight from complex interconnect systems. By connecting RF measurement rigor with digital design challenges, he ensures that theoretical models remain grounded in physical reality. These experts pushed SI into the realm of power integrity, measurement, and compli- ance, especially as data rates and edge speeds accelerated. Modern High-Speed and Application- Focused Era (2010s–present) These voices dominate current conferences, real-world design training, and emerging applications. They emphasize practical imple- mentation, layout discipline, EMI control, and translating SI theory into designs that pass the first time, especially in today's dense, high- speed systems. Rick Hartley Rick Hartley has contrib- uted another critical layer of understanding by focusing on the rela- tionship between signal integrity and electromagnetic compatibility. His teaching consistently rein- forces that signal quality is not defined solely by the trace itself, but by the integrity of the return path. By translating electromagnetic theory into practical layout guidance, Hart- ley helped engineers understand that current does not simply travel forward, it completes a loop, and that loop defines the system's elec- tromagnetic behavior. Daniel Beeker Daniel Beeker adds a more visual and intuitive dimension to this under- standing by demonstrat- ing that signal integrity is fundamentally about elec- tromagnetic space. Through live demonstrations, he reinforces that signals do not exist solely in copper traces, but in the fields surrounding them. His perspective helps engineers move beyond schematic thinking into spatial electromagnetic awareness.
