Synopsys UCIe IP Solutions

Synopsys’ complete Universal Chiplet Interconnect Express (UCIe) IP solution includes controller, PHY and verification IP. The PHY is available in advanced FinFET processes and offers high-bandwidth, low-power and low-latency die-to-die connectivity in a package. The PHY’s flexible architecture supports standard and advanced packaging technologies, delivering up to 4Tbps bandwidth in a multi-module configuration. Synopsys UCIe Controller IP supports widely used protocols such as PCI Express and CXL and enables latency-optimized NoC-to-NoC links with streaming protocols. Synopsys UCIe Controller and PHY IP solutions enable robust and reliable die-to-die links with testability features for known good dies and CRC or parity checks for error correction.
