Siemens Supports Verification of Arm AI CPU

Siemens and Arm have collaborated on the verification of the Arm AGI CPU, a processor designed for agentic AI and hyperscale cloud data center workloads. Siemens used its Veloce hardware-assisted verification technologies to support subsystem and full-system validation of the platform prior to tapeout.

Verification for AI Infrastructure
The Arm AGI CPU is built on the Arm Neoverse Compute Subsystem V3 platform and is intended to deliver energy-efficient, high-performance compute for AI infrastructure and cloud deployments. Siemens’ Veloce Strato CS hardware-assisted verification platform was used to support verification from subsystem level through complete system-on-chip validation.

According to Arm, the workflows were developed jointly with Siemens to support validation of performance, latency and power metrics required for hyperscale deployments. The verification environment used multiple towers of the Veloce Strato CS platform to enable full-system validation of the processor architecture.

The AGI CPU incorporates multi-die compute subsystem designs based on Arm Neoverse V-series cores and includes support for PCIe Gen6, NVMe and CXL technologies. Arm stated that the scale and complexity of these architectures required verification capabilities beyond conventional EDA toolsets.

Hardware-Assisted Verification and Prototyping
In addition to full-chip emulation, Siemens also provided its Veloce proFPGA CS prototyping platform for pre-silicon software development. The FPGA-based prototyping environment enables software validation, driver development and system bring-up before silicon availability.

According to Siemens, the prototyping workflow allows software development to progress in parallel with hardware development schedules. The company stated that this approach supports earlier software readiness and reduces deployment risk for hyperscale infrastructure projects.

Arm said Siemens’ verification solutions enabled large-scale full-system verification of the Arm AGI CPU while supporting performance and efficiency validation for AI infrastructure deployments.

Ecosystem Integration
Siemens stated that its verification and implementation solutions integrate with Arm CPU development workflows and are available to Arm licensees, SoC developers and ecosystem partners.

The company said the same Veloce Strato CS technologies used during development of the Arm AGI CPU can also support custom silicon development on the Arm Neoverse CSS platform. Siemens added that the availability of shared verification technologies across the Arm ecosystem is intended to support development efficiency and reduce time-to-market risks for AI infrastructure projects.

Additional Context
Hardware-assisted verification platforms such as emulation and FPGA prototyping are increasingly used in advanced semiconductor development to validate complex multi-die architectures before tapeout. Technologies including PCIe Gen6 and CXL are becoming standard components in AI and hyperscale computing platforms due to their high-bandwidth interconnect capabilities and support for memory expansion. Verification at full-system scale is particularly important for AI accelerators and cloud CPUs, where power efficiency, latency and software readiness are critical deployment metrics.
