Granite River Labs (GRL), a USB-IF authorized test center, today announced the USB 3.0 Protocol Performance and Stress Test Software Suite (GRL-USB3-PROTO). GRL-USB3-PROTO allows USB developers quickly optimize the performance and robustness of their USB 3.0 products in development while unlocking the full potential of their Teledyne LeCroy Voyager USB 3.0 Analyzer/Exerciser.

The increased speed of USB 3.0 and competitive product landscape presents significant challenges to developers, making it imperative to thoroughly validate product performance and design robustness prior to product launch.

With GRL-USB3-PROTO software, USB 3.0 product developers can use their Teledyne LeCroy USB 3.0 Analyzer/Exerciser to instantly read enumeration information, run raw performance benchmarking, perform randomized protocol stress testing, and characterize protocol error margin tolerance. GRL-USB3-PROTO is designed to provide both functional and protocol testing capabilities to automate USB test cases and methodology development with both direct tests and randomized tests. GRL-USB3-PROTO software automates the Analyzer/Exerciser equipment helping developers save time they’d otherwise have to spend developing test scripts from scratch.

GRL-USB-PROTO offers a number of significant advantages compared to traditional PC-based tools like CrystalDiskMark: more accurate response time for SCSI Write/ Read operations, more consistent and reliable timing results, cleaner transactions, and protocol trace file accessibility for deeper analysis. As a result, devices tested with GRL-USB-PROTO can show significant read and write performance increases vs PC-based tools.

"Teledyne LeCroy believes that third party tools such as GRL's USB 3.0 Protocol Performance and Stress Test Software Suite bring value to developers who are interested in optimizing the performance of their USB 3.0 products," said Kimberly McKay, product line manager of embedded instruments at Teledyne LeCroy.

“Granite River Labs is proud to offer our USB 3.0 Performance Benchmarking and Protocol Validation Software Suite for Teledyne LeCroy USB 3.0 Analyzer/Exerciser users,” said Johnson Tan, GRL chief executive officer. “GRL remains deeply committed to supporting the USB ecosystem and by meeting the growing need for a protocol testing tool looks forward to supporting USB adopters who leverage this tool.”
