Siemens has collaborated with Arm to verify the Arm AGI CPU using Siemens’ Veloce Strato CS hardware-assisted verification platform. The verification covered the CPU from subsystem through full-system level to support its use in scalable agentic AI and cloud data center deployments. The Arm AGI CPU is built on the Arm Neoverse Compute Subsystem (CSS) V3 platform and is designed to deliver high-performance, energy-efficient compute for agentic AI and hyperscale environments. Siemens’ solutions were applied to address performance, latency, and power targets prior to tapeout.
Arm utilized Siemens' hardware-assisted verification (HAV), emulation, and prototyping solutions for the Neoverse V-series Compute Subsystem (CSS). The workflows were engineered in collaboration with Arm to validate key performance metrics for hyperscale deployments.
“The scale and complexity of modern AI compute platforms demand an enhanced level of verification,” said Karima Dridi, vice president of productivity engineering, Arm. “Siemens’ solutions enabled full-system verification of the Arm AGI CPU at scale using multiple towers of Veloce Strato CS, helping to ensure it meets the performance and efficiency requirements of hyperscale deployments.”
The design incorporates multi-die CSS with Neoverse V-series cores, high-speed interconnects, PCIe Gen6, NVME, and CXL. Veloce Strato CS handled full-chip verification at scale. Siemens’ Veloce proFPGA CS prototyping platform supports pre-silicon software development by providing FPGA-based prototypes that run at near-real-time speeds, allowing software validation, driver development, and system bring-up ahead of silicon availability.
"The Arm AGI CPU exemplifies the engineering ambition driving agentic AI innovation," said Jean-Marie Brunet, senior vice president and general manager of Hardware-Assisted Verification, Siemens Digital Industries Software. "Working with Arm helps to ensure Siemens' verification technology can verify complete Neoverse CSS subsystems in a full SoC model at industry-leading performance and channel bandwidth."
The same Veloce Strato CS technologies used for the Arm AGI CPU are available to Arm licensees, SoC designers, and ecosystem partners. This supports adoption in Arm-based designs for hyperscalers building custom silicon on the Neoverse CSS platform.
