100G Ethernet Verification IP

Overview

Comprehensive MAC-to-PCS Protocol Validation Solution

The 100G Ethernet Verification IP (VIP)  offers a robust and high-performance solution for validating the critical MAC-to-PCS datapath in 100 Gigabit Ethernet systems. Designed to ensure protocol compliance, the VIP facilitates the generation, transmission, reception, and monitoring of various Ethernet MAC frame types, all while adhering to IEEE 802.3ba and related standards. Whether you are working on IP, subsystem, or SoC-level verification, this VIP is your go-to solution for comprehensive Ethernet testing.

The 100G Ethernet VIP is built on a SystemVerilog foundation and follows the UVM 1.2 methodology, providing a flexible, modular architecture. Key components include:

  • Sequencer & Sequence Library: Generates randomized and directed MAC frame traffic
  • Driver (Transmitter): Converts MAC frames into encoded PCS blocks
  • Monitor (Receiver): Captures and validates PCS-aligned data, reconstructing MAC frames
  • Error Injection Engine: Introduces faults like sync header corruption and lane misalignment
  • Assertions & Coverage Collectors: Ensures functional coverage for thorough validation

This layered structure allows the VIP to function as a transmitterreceiver, or passive monitor, adaptable to various verification environments.

Key Features

End-to-End Visibility & Control

  • The 100G Ethernet VIP provides complete visibility over the Physical Coding Sublayer (PCS), ensuring precise validation of encoding, lane distribution, synchronization, and alignment before data reaches the PMA/PMD layers.

Wide MAC Frame Support

  • Standard Ethernet frames (64–1518 bytes)
  • Jumbo frames (up to 9K bytes)
  • VLAN-tagged and double-tagged (Q-in-Q) frames
  • Pause and control frames
  • Custom and error-injected frames for stress testing

 

Advanced Error Injection and Recovery

  • Simulate real-world fault scenarios with error injection capabilities such as sync header corruptionlane misalignmentblock disparity, and lane skew. Validate your system’s error recovery logic to ensure reliability under stress conditions.
