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

Touchstone Models and Scattering Parameters: Fundamentals and Importance in SI/PI Touchstone® (SnP) models are a key asset in the fields of signal integrity (SI) and power integrity (PI) when analyzing high-data rate, high-speed designs. These frequency-domain models characterize the linear behavior of passive interconnects and components such as PCB traces, vias, connectors, and packages by describing how signals are reflected and transmitted at various ports across a wide r
