Signal Integrity, Power Integrity, & EMC Blog 

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

We've partnered with leading manufacturers like Texas Instruments, Analog Devices, and Renesas to provide you with a comprehensive suite of pre-defined component models, including VRMs, regulators, and passive components. This powerful library is designed to support true end-to-end simulation, allowing you to seamlessly integrate your custom ASICs, GPUs

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

When we teach about S-parameters and modeling, someone never fails to ask “What is causality?”  or “What happens if a model isn’t causal?”  Our go-to explanation is that it's a cause and effect thing: a system is causal if its output doesn’t respond before its input changes. In a causal universe, the light shouldn't turn on before you flip the switch. This seems straightforward. After all, if you're modeling or measuring a physical system — say, interconnects between a drive
