Overview
Synopsys delivers DesignWare interface IP that lets AI SoCs disaggregate connectivity into small I/O chiplets. The 1.6T Ethernet MAC IP, based on IEEE 802.3 for 400G/800G/1.6T applications, is paired with a full PHY, Controller and Verification IP suite, and complements the company’s UCIe die-to-die PHY and Controller solutions.
The portfolio includes a 40G UCIe PHY on Samsung SF4X, D2D Controller IP and HBM3/3E Controller IP, plus PCIe 6.0 PHY on TSMC N3P and PCIe Gen7 PHY. UCIe provides native mapping for PCIe, CXL and streaming protocols, enabling multi-die packaging where PCIe/CXL, Ethernet, UCIe and HBM connectivity are moved off the main AI die onto reusable I/O chiplets.
Key Benefits
Complete 1.6T Ethernet and UCIe IP with PHY, Controller and Verification components. Advanced-node proven on TSMC N3P/N3E and Samsung SF4X. Disaggregation-ready — offload PCIe, CXL, Ethernet and HBM connectivity to reusable I/O chiplets.
Applications
AI SoC and accelerator I/O chiplets, multi-die chipsets using UCIe, 1.6T/800G/400G Ethernet subsystems, HBM3/3E memory interfaces, and PCIe 6.0/7.0 connectivity for datacenter silicon.
