SANTA CLARA, Calif., May 01, 2025 (GLOBE NEWSWIRE) — Movellus today announced the industry’s first on-chip sensor for power delivery network (PDN) characterization and monitoring. Power integrity is vital to the performance and efficiency of any system-on-chip (SoC). However, the industry has very limited visibility into the behavior of on-chip PDNs, which can result in voltage over-margining (compromising both power and performance), missed performance targets, and higher DPPM rates. And as the industry evolves to larger SoCs, stacked die, and chiplets, the problem is further magnified, making PDN visibility even more critical to overall system performance and energy efficiency. PDN IQ enables improvements in power, performance, and uptime for advanced semiconductors by providing PDN visibility across the entire silicon lifecycle from bench characterization and production test to in-field monitoring.
“Robust PDN operation is required to ensure the functionality and performance of high end SoCs. Today, the industry relies on a variety of black-box techniques to evaluate these critical networks, but these approaches are becoming less effective in the face of ever larger devices, advanced packaging, and severe power swings in workloads.” said Ranganathan “Suds” Sudhakar, Chief Development Officer at d-Matrix. “Having direct visibility of PDN efficacy, anywhere on chip, is a compelling mechanism to optimize the power-performance characteristics of large SoCs and will be a game changer for the industry.”
