USB 4.0

Ensures protocol accuracy, tunneling, and PD behavior in simulation.

Overview

USB 4.0 Verification IP is a high-performance testbench component designed to validate USB 4.0 protocol functionality. It supports up to 40 Gbps, protocol tunneling (PCIe, DP, USB 3.2), Power Delivery, and multi-lane configurations.

This VIP is ideal for verifying USB 4.0 controllers in SoCs, validating tunneled protocols, and testing alternate mode implementations. It enables early bug detection, compliance checking, and system-level integration verification.
