Original analysis of power integrity challenges shaping AI silicon, data center economics, and chip architecture.
The physics of transient voltage noise now determines what frequencies chips can sustain, what margins designers must hold, and what workloads data centers can run.
Building a complete board-to-transistor model of NVIDIA’s Hopper GPU in PDNLab, and what it reveals about the spatial distribution of voltage droop.
Fast-switching AI workloads are stressing the chip power grid and inducing noise in ways unseen by current industry tools. Anasim calls this Cumulative Voltage Droop and studies its relationship to the data-center industry’s growing problem of Silent Data Corruption in modern chips.
A 158-grid power delivery model of the NVIDIA H100 exposes the voltage droop dynamics that define the electrical limits of modern AI accelerators — including a counter-intuitive result about workload sequencing.
The software running on a chip determines the electrical stress it experiences. Co-design means modeling the workload and the power grid together, before silicon exists.
