USB 3.0 協議壓力測試軟體 (GRL-USB3-PROTO)

簡介

概述

GRL的USB 3.0協議性能和壓力測試套件（GRL-USB3-PROTO）與Teledyne LeCroy合作開發，使用戶能夠充分利用Voyager。在過去，用戶必須開發自己的腳本來實現功能和協議壓力測試。現在借助GRL-USB3-PROTO ，用戶可以即時讀取信息，執行原始性能基準測試，實現隨機協議壓力測試以及協議錯誤容限。GRL-USB3-PROTO提供易於使用的Windows 介面工具，而不影響性能的驅動程序，操作系統和系統負載效應。而且，GRL-USB3-PROTO提供精確的錯誤注入控制和詳細的協議跟踪記錄功能，僅適用於Voyager。 GRL-USB3-PROTO可用於任何Windows 7/8 PC，釋放了Voyager的全部潛力，使USB開發人員能夠輕鬆快速地優化其USB 3.0產品的性能和穩定性。

主要功能

• Leverage FPGA based host for performance benchmarking under ideal conditions
• Run low level multiple SCSI reads and write commands and measure raw performance without having to deal with driver or operating system overhead
• Specify read/write addresses and choose between sequential or random addressing
• Define read/write data block sizes and patterns
• Produce verifiable performance metric reports backed by full protocol traces
• Optimize performance to show much higher read/write metrics compared to PC tools
• Add various protocol errors and non-ideal conditions to determine impact on performance

• Determine protocol error injection impact on USB 3.0 Device stability and performance
• Select individual or a combination of protocol errors to assert on DUT
• Select from a range of random error injection parameters and iterations
• Select from a range of random size storage memory transfers and transfer iterations
• Automatically generate exerciser scripts for each iteration and continually step through different random parameter combinations
• Perform automated characterization of DUT’s protocol error margin tolerance for each error
• Explore how combinations of errors can create problems even within operating ranges of error parameters showing no problems when error parameters are run individually
• Increase test coverage and probability to identify issues
• Produce detailed traces and error injection logs showing error injection history
