The Ellisys USB Explorer 280 is a sophisticated protocol test and analysis system for USB 3.0 SuperSpeed 5Gbps traffic monitoring, driver and software stack debugging, and performance analysis. The USB Explorer 280 is designed to reduce R&D time by finding issues early and debugging more efficiently, and can improve quality and reliability by verifying adherence to the specification.
Analyze USB 3.0 (SuperSpeed) and USB 2.0 links (High Speed, Full Speed, Low Speed)
Emulate USB hosts and devices
Automatically detect link speed and SS receivers
Upload and display live data during recording
Record LFPS states and display state transitions
Connect to differential SMA for alternative front-end probing during prototype stages
The Ellisys USB Explorer 280 Analyzer includes extensive protocol analysis features, including real-time monitoring and live upload of captured traffic, detailed decoding of standard and class requests, trigger, filter, and search functions, and comprehensive statistical analyses. Automated support for spread spectrum clocking (SSC), data scrambling, and receiver equalization techniques is included.
The USB Explorer 280 Analyzer is based on the intuitive Ellisys Visual USB™ software application that is well-proven for performance optimization and validation of device enumeration, bus operation, and interoperability testing. New analysis features designed specifically for USB SuperSpeed have been added to provide the user with a comprehensive analysis solution ideal for any USB design effort.
The Ellisys USB Explorer 280 Generator supplements protocol analysis by emulating USB hosts and devices. The USB Explorer 280 Generator is ideal for testing corner cases, error recovery protocols, link power state transitions, and link training issues. The Generator includes a low-level, powerful scripting interface favored by engineers looking to control protocol sequences and responses at precise timing granularities.
The Ellisys USB Explorer 280 Duo is a highly flexible bundle of two full-featured units that can be used as one analyzer and one generator, two analyzers, or two generators, depending on the needs of the user. Even more convenient that simply having these two functions on a single hardware unit, this innovative and flexible architecture allows engineers to share units among the R&D team.
Analyzer Applications
USB host and device traffic monitoring
Drivers and software stacks debugging
Performance analysis
Link state analysis
Analyzer Features
Automatic detection of link speed
Automatic detection of SS receivers
Hardware triggering and filtering
InstantTiming™ view for graphical, intuitive understanding of bi-directional traffic elements and critical timing measurements
Typical Analysis Setup
The USB Explorer 280 is connected in a logically passive mode to record traffic and bus events passing between host and device. The analyzer provides same-link concurrent support for USB 3.0 and USB 2.0 speeds, which is especially valuable for development of hubs supporting USB 3.0 and USB 2.0 specifications. | |

Generator Applications
USB host and device emulation
Testing of error recovery mechanisms
Stress testing for performance
Compliance verification
Generator Features
Generation of arbitrary packets with precise timing
Error injection capabilities to test recovery mechanisms
Replay of traces captured by analyzer
Powerful scripting environment with integrated editor and debugger
Host Emulation Setup
The USB Explorer 280 Generator is connected through a USB Explorer 280 Analyzer to a USB device. The Generator emulates the automated protocol processes of the USB host, while allowing the user full control over these processes, including arbitrary packet and error generation. The Analyzer records all traffic and gives realtime performance and compliance information. | |

July 2012: Cypress Demonstrates Maximum FX3 Throughput with EX280
Ellisys USB 3.0 analysis software
The following screenshot shows the Ellisys USB 3.0 analysis software. A Mass Storage trace is open and a SCSI Read transfer is open down to the packets.
This screenshot shows a full overview of the Mas Storage traffic in the Instant Timing view. The two lines represent the upstream (top) and downstream (bottom) links. Green represents IN transactions and blue OUT transactions. The first part of the traffic is bursted and achieves about 400 MB/s while the following traffic shows Not Ready mechanism and achieves about 100 MB/s.
The next screenshot is more zoomed-in and we can distinguish packets and ordered sets. The gray blocks are TSEQ ordered sets. Both brown and green packets are flagged because low-level errors have been detected.
This screenshot is even more zoomed-in and symbols can now be distinguished. We can clearly see which symbol is erroneous.
Ellisys USB 3.0 generation software
The following screenshot shows the Ellisys USB 3.0 generator IDE. A script emulating Mass Storage traffic is open. This software can be used to edit, run and debug scripts all within the same environment.
Ellisys USB 3.0 Examiner compliance suite
The Ellisys SuperSpeed compliance software detects automatically the capabilities of the host or of the device, and displays the relevant tests accordingly. A simple click will run all necessary test and a compliance report will be generated at the end of the session.
