Signal Integrity, Power Integrity, & EMC Blog 

In power integrity analysis, we primarily concern ourselves with the impedance response when evaluating the frequency domain. Specifically, we focus on the magnitude   of the impedance response and tend to neglect the phase   of the impedance response. After all, the phase can be extracted from the magnitude: Flat impedance magnitude across frequency is purely resistive with 0° phase -20 dB/decade slope is purely capacitive with a -90° phase +20 dB/decade slope is purely indu

Achieve First-Pass Success in AI and Chiplet Designs with Measurement-Validated SIPI Modeling The future of high-performance computing—AI accelerators, custom ASIC design, and complex Multi-Chip Modules (MCMs)—is defined by advanced packaging. However, as process nodes shrink and data rates soar past 112 Gbps , and even 224 Gbps , the package substrate has become the single greatest risk to performance and time-to-market. At Signal Edge Solutions, we don't just simulate; we

Control loop stability is critical  to the performance of any system, influencing everything from closed-loop parameters to system noise. Unfortunately, verifying stability is often a major challenge. For many devices—like voltage references, fixed voltage LDOs, and integrated POLs —traditional Bode plot assessment is simply not feasible  because the feedback loop is inaccessible or requires destructive modification of the PCB . Furthermore, Bode plots fail for complex system

Example Co-Simulation Results After setting up your Keysight ADS workspace and dropping in our SI/PI models , the real power of our SI/PI library becomes clear. Our pre-defined component models, which include state-space average VRM models, regulators, and other essential components, are built for comprehensive power integrity analysis. They provide the foundation for powerful co-simulations that give you a complete picture of your design's performance. Before tackling advanc
