First verification IP for PHY covering multiple protocols

1 min read

Cadence Design Systems has announced the availability of the first Verification IP (VIP) for physical layer (PHY) verification.

The Cadence VIP for PHY covers multiple protocols and allows customers to test and optimise their PHY designs, accelerating the development of data centre, artificial intelligence (AI), machine learning (ML) and mobile application designs.

The Cadence VIP for PHY provides customers with a comprehensive verification solution for the most complicated and challenging physical-layer interfaces and protocols, including PIPE 5.2 for PCI Express (PCIe) 5.0, USB3 and USB4, DFI for LPDDR4, DDR5 and HBM2E, and MIPI D-PHYsm/C-PHYsm for CSI-2sm 2.0 and DSIsm 2.0. With the PHY VIP, customers will be able to shorten time to market through advanced built-in capabilities for PHY verification such as:

• PHY-level timing checks
• Ability to drive protocol-aware and protocol-agnostic traffic for exhaustive testing
• A built-in scoreboard for analysing receive path, transmit path and loopback
• Control over jitter, spread spectrum clock and bit error rate

In addition, the solution includes Cadence TripleCheck technology, which provides users with a PHY-related verification plan that is linked to the specification as well as comprehensive coverage models and a test suite to ensure compliance with the interface specification.

“Our PHY team has successfully utilised Cadence VIP for verification of various protocols such as USB3 and PCIe 4.0, enabling us to quickly deliver unique and innovative designs for a broad range of applications,” said Realtek’s Vice President and Spokesman, Yee-Wei Huang. “With the complexity inherent in verifying PHY designs, Cadence VIP for PHY addresses a critical and challenging verification task and provides the speed and accuracy we need to help our customer’s time to market.”

“PHY verification requires unique methods to ensure that all timing, power and throughput requirements are met in various conditions,” said Moshik Rubin, Verification IP product management group director, System and Verification Group at Cadence. “With the industry’s first dedicated VIP for PHY, we’re enabling our customers to verify their PHY designs effectively, ensuring the designs comply with the standard specification and meet application-specific performance metrics to provider the fastest path to IP verification closure.”
