On Oct. 14, 2025, Astera Labs announced that it has joined Arm Total Design, a comprehensive ecosystem that accelerates custom system‑on‑chip development based on Arm Neoverse Compute Subsystems. The partnership combines Astera Labs’ Intelligent Connectivity Platform with Arm’s Neoverse CSS to deliver chiplet‑based solutions for rack‑scale AI infrastructure. The collaboration is designed to provide customers with validated, interoperable connectivity from day one.
The alliance will enable the integration of Astera Labs’ PCIe, Ethernet, CXL, and UALink technologies into Arm’s chiplet architecture, allowing hyperscalers to mix and match compute, memory, and networking components in a modular fashion. By leveraging Arm’s compute subsystems alongside Astera Labs’ connectivity, customers can accelerate time‑to‑market for new AI platforms while maintaining open‑standard compatibility. The partnership also offers a supply‑chain‑diverse, multi‑vendor ecosystem that supports rapid scaling of AI workloads.
For Astera Labs, joining Arm Total Design expands its reach into the growing chiplet market and positions the company as a key enabler of next‑generation AI infrastructure. The collaboration strengthens the company’s competitive moat by combining its first‑to‑market interconnects with Arm’s proven compute cores, creating a differentiated solution set for hyperscalers. The partnership enhances the company's ability to deliver validated, end‑to‑end solutions that reduce integration risk and lower total cost of ownership for AI data centers.
The announcement underscores Astera Labs’ commitment to open‑standard, software‑defined connectivity and its strategy to support the AI Infrastructure 2.0 transition. By partnering with Arm, the company can deliver end‑to‑end, validated solutions that reduce integration risk and lower total cost of ownership for AI data centers. The move is a strategic milestone that aligns with the company’s growth trajectory and reinforces its leadership in AI connectivity.
