High-Performance AI GPU and FPGA Load Simulator

The PactivR Orac is a unified, high-performance AI GPU and FPGA Load Simulator designed to help chip designers, board designers, and power integrity engineers validate and characterize power delivery networks (PDNs) faster and more efficiently. The platform combines Pactiv transient and DC load hardware with the Orac AI-enhanced controller, giving engineering teams a more automated way to test real-world silicon load behavior compared to conventional PDN validation methods.

With up to 1.5 kW of test power, 900 A continuous DC load capability, 1800 A instantaneous current, and sub-50 ns transient edges, PactivR Orac recreates the fast load dynamics found in advanced processors, ASICs, FPGAs, GPUs, and AI accelerators. Its architecture includes 30 programmable LoadCells across 20 differential sense channels, allowing teams to evaluate complex power delivery behavior with greater speed, accuracy, and repeatability.

By automating demanding transient load testing and PDN characterization, PactivR Orac helps reduce manual setup time, accelerate validation by approximately 200× compared to passive or conventional active approaches, and shorten the path to reliable, high-performance power delivery designs.
