Overview

Silicon agnostic and fully compliant implementation of UALink_200 specification

The UA Link DL IP Core is a high-performance, silicon-agnostic and fully compliant Data Layer implementation of UALink_200 specifi cation. Designed for seamless integration into accelerator, switch, and SoC designs, it delivers deterministic low-latency, robust error correction, and compatibility with multiple high-speed Ethernet-derived link rates.

This IP core bridges the UALink Transaction Layer (TL) to the UA Link Ethernet Physical Coding Sublayer (PCS), ensuring optimized fl it packing and unpacking, coordinating changes to the link, and providing a UART mechanism for fi rmware-controlled sequence passing as defi ned in UALink_200 Standard. It is ideal for systems requiring 200–800 Gbps per Link/Station with industry leading signal integrity and interoperability.

Key features

  • UALink_200 Specifi cation Compliant: Implements DL functions per Rev 1.0
  • Multi-Rate Support : 200 GBASE-KR1/CR1, 400 GBASE-KR2/CR2, 800 GBASE-KR4/CR4
  • Tx Pacing/Rx rate adaptation
  • Provides a Data Link Layer message service between link partners
  • Link Level Replay on 640 Byte fl it basis
  • 32 bit CRC for error checking
  • Targeting both ASICs and FPGAs

UALink Under the Hood: Why Full-Stack Verification Wins

Verifying UALink means following a transaction the way the silicon does: down through four layers, out across one, two, or four SerDes lanes at the configured 100G or 200G serial rate, and back again, with its meaning and its bytes both intact. This blog takes that journey one layer at a time, and along the way examines a detail of the data link flit that is easy to overlook and important to get right.

Securing Scale-Up AI: Cadence’s Complete UALink Solution

As an early contributor to the UALink ecosystem, Cadence delivers a production-ready solution built for real-world AI deployments. By combining high-performance connectivity IP with integrated security, Cadence enables customers to scale AI infrastructure with confidence.

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.
