Signal Integrity, Power Integrity, & EMC Blog 

Calibration and measurement accuracy are critical in power integrity and impedance analysis, but they’re often hindered by time-consuming setups, inconsistent connections, and external interference. Picotest’s new Calibration Test Fixture (CTF) addresses these challenges head-on, offering a faster, easier, and most importantly, repeatable measurement process. By eliminating the need for SMA connectors on mount boards and integrating internal ground loop isolation, the CTF str

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

Diagram of sample Signal Edge Solutions mobile lab setup In an increasingly RF connected world, EMC compliance testing is necessary to ensure products are robust enough to operate in a safe and reliable manner in consumer and commercial environments. Nearly every country has EMC regulations and standards that electronic devices or machines on the market must be compliant with for their intended use. Products that fail to meet electromagnetic compatibility (EMC) compliance can

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
