Hardware-assisted verification is becoming increasingly important as AI chips grow larger, more complex and more software-dependent. A recent collaboration between Siemens and Arm demonstrates how hardware-assisted verification (HAV) is helping validate next-generation AI infrastructure before tapeout.

According to Siemens, its Veloce™ Strato CS platform was used to support verification of the new Arm AGI CPU, built on the Arm Neoverse® Compute Subsystem (CSS) V3 platform. The processor is designed for high-performance, energy-efficient compute targeting agentic AI and hyperscale cloud deployments.

Why Hardware-Assisted Verification Matters for Modern SoCs

The announcement highlights how HAV is evolving into a critical part of modern ASIC development workflows. As SoCs integrate multi-die architectures, PCIe Gen6, NVMe, CXL, and increasingly complex interconnects, traditional simulation-only approaches are becoming harder to scale efficiently.

Siemens shared that Arm used multiple towers of Veloce Strato CS for subsystem and full-system verification. This enabled validation of performance, latency, and power targets before silicon availability – an increasingly important requirement for hyperscale deployments where delays can significantly impact schedules and costs.

Pre-Silicon Software Validation and FPGA Prototyping

The collaboration also demonstrates the growing role of pre-silicon software development in AI chip projects. Siemens’ Veloce proFPGA CS prototyping platform was reportedly used to accelerate software validation and system bring-up ahead of tapeout, helping software teams begin validation, driver development, and system bring-up months ahead of silicon availability.

For verification engineers, the announcement reflects several broader industry trends:

Greater adoption of hardware-assisted verification for AI chips
Increasing complexity in multi-die and chiplet-based SoCs
Earlier software validation during hardware development
Rising demand for scalable verification workflows
Stronger focus on power efficiency in AI infrastructure

Siemens also noted that the same verification technologies used during development of the Arm AGI CPU are available to Arm partners and licensees. This could help accelerate adoption of scalable verification workflows across the broader AI hardware ecosystem.

As AI compute platforms continue to evolve, hardware-assisted verification is becoming increasingly important for validating complex SoCs at scale. For ASIC and verification teams, the ability to combine emulation, prototyping, and full-system validation earlier in the design cycle is becoming critical for meeting aggressive performance and deployment targets.
