Validating UPLI Protocol Across Topologies with Cadence UALink VIP

The UPLI (UALink Protocol Level Interface) is a logical signaling interface that facilitates communication between devices—specifically between originator devices (which initiate transactions) and completer devices (which respond to them). Each transaction comprises a request and a corresponding response, forming a complete communication cycle. Cadence UALink VIP supports various topologies to verify UPLI layer of DUT.

Powering Scale Up and Scale Out with 224G SerDes for UALink and Ultra Ethernet

At the recent ECOC 2025 conference in Copenhagen, Cadence showcased its key role in enabling the future of AI infrastructure with live silicon demonstrations of several essential IP technologies for emerging 800G and 1.6T networks. Powered by Cadence's 224G SerDes IP, Cadence's Ultra Accelerator Link (UALink 1.0) scale-up and Ultra Ethernet scale-out networking solutions deliver the performance, flexibility, and interoperability needed for next-generation AI factories and hyperscale data centers.
