Architecting a Modular UVM Test bench for the Verification of Complex 800G Ethernet on-Chip Protocols

The proposed UVM-based verification environment effectively addresses the complexities of 800ZR coherent interfaces by providing a scalable and automated framework for high-throughput testing. Through the integration of a bit-accurate oFEC reference model and a robust transaction-level architecture, we successfully validated the critical synchronization between 512-bit data payloads and their corresponding 64-bit parity codes. The simulation results, as evidenced by the timing waveforms, confirm that the environment maintains strict protocol compliance across reset sequences and high-speed burst transfers. Ultimately, this methodology reduces verification bottlenecks, ensuring that 800G optical networking hardware meets the rigorous reliability and latency requirements of modern data center interconnects.
