How to Simulate Low Voltage, High Power 2000 Amps to a Dynamic Digital Load

EM simulators that are optimized for PCB PDN simulations provide an increased level of automation to enable the basics of DC IR Drop, electrothermal, and AC impedance for early detection of design issues. In this article, Heidi Barnes, Steve Sandler, and Benjamin Dannan examine why the ability to optimize a PDN for ZTarget with PCB parasitics in the frequency domain and then export to an end-to-end PI Digital Twin simulation for validation in the time domain should be standard practice for the PI engineer.

Who Put That Inductor in My Capacitor?

This article covers the importance of proper calibration, measurement, and de-embedding to ensure that the final capacitor model is free of errors, allowing an accurate representation of the PDN used in simulation. While capacitor models may play a seemingly minor role in the overall system design, the impact of capacitor models can significantly impact the system design and, importantly, design sign-off.
