Keysight Press – System Designer Design Solution for USB4

Keysight Technologies, Inc. (NYSE: KEYS) today introduced System Designer for USB, a comprehensive design solution that supports the latest USB4® standards—Gen2, Gen3, and Gen4. Tailored for high-speed digital USB applications in personal computers, mobile devices, and edge AI, the platform delivers an integrated environment for modeling, simulating, and validating USB4® interfaces. By combining a smart workflow with simulation-driven virtual compliance testing, System Designer for USB aims to accelerate time-to-market and reduce design risks associated with complex multi-channel, multi-level USB configurations.

As data throughput demands rise, designers face the challenge of ensuring reliable USB communication for large-scale data transfers. The USB4® specification addresses this need by delivering speeds up to 120 Gbps and employing three-level pulse-amplitude modulation (PAM3) within the popular USB-C® connector. System Designer for USB leverages these modern standards to provide early-stage validation of signal integrity, link training, and performance, helping engineers identify bottlenecks and compliance issues before hardware prototypes are available.

Key features of System Designer for USB include a streamlined environment that simplifies the setup of multi-link, multi-lane, and PAM3 configurations through a guided, smart workflow. The solution’s USB Algorithmic Modeling Interface (AMI) modeler supports both Non-Return-to-Zero (NRZ) and PAM3 modulation schemes, enabling rapid implementation of high-speed USB links. Integrated compliance-test simulations automate critical validation steps, reducing design iterations, minimizing re-spins, and cutting overall development costs. Simulation-driven insights help engineers resolve signal integrity challenges early and efficiently.

Beyond its core modeling capabilities, System Designer for USB enhances overall design productivity by offering a unified interface that integrates simulation setup, execution, and results analysis. The platform’s streamlined workflow reduces manual configuration steps, enabling engineers to focus on architectural decisions rather than toolchain intricacies. By delivering virtual compliance tests early in the design phase, users can achieve first-pass success rates on physical compliance tests, significantly shortening validation cycles and accelerating the release of USB-enabled products to market.

According to Hee-Soo Lee, High-Speed Digital Segment Lead at Keysight EDA, “Our standards-driven workflow delivers industry-leading accuracy in signal integrity analysis and compliance validation. By shifting compliance verification earlier in the design cycle, engineers can save significant time and cost. System Designer for USB empowers customers to adopt advanced digital standards, streamlining development and reducing the risk of costly hardware re-spins.”
