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.
