The continued expansion of AI and LLM processing requires high bandwidth and low latency in hyperscale data centers.
Semiconductor design firm Synopsys believes that adopting a silicon roadmap that supports faster Ethernet is the way forward, providing chipmakers with the essential IP needed to develop high-speed networking silicon. Announcing an Ethernet solution.
This sounds like a very forward-thinking idea, given that the IEEE is expected to finalize the 1.6T Ethernet standard in 2026, but the standard’s baseline feature set will be limited to 802.3dj tasks. It is expected to be completed this year by the Force.
Increased Ethernet speed
The Synopsys design supports 4 x 400G, 2 x 800G, and 1.6T Ethernet rates with 112 Gbps and 224 Gbps SerDes. The solution includes a 224G Ethernet PHY and verification IP, 1.6T media access control (MAC), and physical coding sublayer (PCS) components. The California company says its 1.6T MAC and PCS Ethernet controller reduces interconnect power by up to 50% and reduces latency by 40% compared to previous generations with its patented Reed-Solomon forward error correction architecture. says it will reduce it.
The need for faster Ethernet speeds is, of course, driven by AI’s ever-increasing data demands.
“The massive computing demands of hyperscale data centers require significantly faster Ethernet speeds to enable new AI workloads,” said John, senior vice president of IP marketing and strategy at Synopsys. Koeter said.
“With our complete IP solution for 1.6T Ethernet, pre-validated subsystems, successful ecosystem interoperability, and decades of expertise in developing and delivering the broadest interface IP portfolio in the industry, , designers can confidently integrate the functionality they need into their SoCs while reducing risk.”
“As demands from large-scale language modeling, HPC simulation, and AI training in hyperscale data centers grow, the network boundary is crossing the terabits per second threshold,” said Peter Jones, Chairman of the Ethernet Alliance. says. “The availability of development tools that can meet these needs is critical to the success of next-generation Ethernet standards that serve this market.”
Synopsys’ 1.6T Ethernet solution, including all components, is available now and has already been deployed by “multiple customers,” Synopsys said.
