Signal Integrity Journal Webinar Series

Title: 2000 Amp PCB Power Delivery Design, Simulation, and Measurement Challenges

Date: May 9, 2024

Time: 8am PT / 11am ET

Sponsored by: Keysight Technologies

Presented by: Heidi Barnes, Senior Application Engineer and Power Integrity Product Owner, Keysight Technologies and Benjamin Dannan Chief Technologist, Signal Edge Solutions

Abstract:
Massive processors for big data, AI, and 100+ Gigabit communications are already reaching 2000 Amps on their core power rails. The next generation of AI/ML ASICs will reach 5000 Amps in just a few more years. This presentation will discuss critical aspects of designing, simulating, and measuring high-current power rails and assessing available topologies to balance performance and cost trade-offs. You will learn how to:

• Simulate with multi-phase parallel VRM models to predict PDN impedance and large and small signal responses in the time domain.
• Include PCB EM models for DC IR drop, thermal, and AC decoupling to analyze the smallest PCB artifacts and the impact on the desired micro-ohms target impedance.
• Measure and validate the 2000 Amp power rail using a unique ultra-high-speed transient step loader with ns response times to reach 100% duty cycle for testing thermal and electrical design limits.
