Best-in-class PIPE PHY Verification IP for your IP, SoC and, system-level design testing.

The Cadence® PIPE PHY Verification IP (VIP) provides a mature, highly capable verification solution for the PHY layer of complex protocols such as PCIe 3/4/5, USB-3.x, USB-4, DisplayPort and SATA at the Intel PIPE (PHY Interface for PCI Express*, SAA, USB-3, DisplayPort, and Converged IO Architectures). The VIP supports simulation platform and enables metric-driven verification of IP and System on Chip (SoC) designs against PIPE PHY protocol specifications. PIPE PHY VIP is compatible with the industry-standard Universal Verification Methodology (UVM) and supports all leading simulators.

Supported Specifications: Intel PIPE version 4.3, 4.4,1 and 5.2 specifications.
