Teledyne LeCroy has developed six generations of its industry leading USB protocol verification system since the introduction of USB in 1995. Each successive generation of the Teledyne LeCroy USB analyzer family has built upon the previous knowledge and expertise. Today, Teledyne LeCroy offers a broad range of USB test systems with unprecedented functionality, accuracy and user friendliness. The enormous cost of discovering problems after a product is released far outweighs the investment in Teledyne LeCroy's de-facto standard USB analysis tools. Their use improves the speed and efficiency of the debug, test and verification for USB semiconductor, device, and software vendors. Analyzers or bus "sniffers" also play an essential role in avoiding costly interoperability problems by allowing developers to verify compliance with the USB specification.

Consistent with the growing popularity of digital media, the USB-IF announced USB 3.0 in late 2007 targeting 10X the current USB bandwidth by utilizing two additional high-speed differential pairs for "SuperSpeed" transfer mode. The USB 3.0 specification was released in late 2008 and commercial products began shipping in late 2009. Teledyne LeCroy has pioneered the development of verifications systems for this new technology. The only company that offers a complete line of USB 3.0 test solutions covering transmitter test to protocol test, and every step in between, Teledyne LeCroy helps developers achieve their goals of performance, quality, reliability and time-to-market for SuperSpeed technology.

USB Technology Overview:

USB, or Universal Serial Bus, is a connectivity standard that enables computer peripherals and consumer electronics to be connected to a computer without reconfiguring the system or opening the computer box to install interface cards. The USB 1.0 specification was introduced in January 1996. The original USB 1.0 specification had a data transfer rate of 12 Mbit/s The first widely used version of USB was 1.1, which was released in September 1998. It provided 12 Mbps data rate for higher-speed devices such as disk drives, and a lower 1.5 Mbps rate for low bandwidth devices such as joysticks. USB 2.0 specification was released in April 2000 and was ratified by the USB-IF at the end of 2001 to develop a higher data transfer rate, with the resulting specification achieving 480 Mbit/s

USB today provides a fast, bi-directional, low-cost, serial interface that offers easy connectivity to PCs. A hallmark for USB operation has been the ability for the host to automatically recognize devices as they are attached and install the appropriate drivers. With features such as backward compatibility with previous devices and hot "plug-ability", USB has become the de-facto standard interface for various consumer and PC peripheral devices. The USB standard allows up to 127 devices connected to a Host System. USB designates low, full, high-speed connectivity between devices compatible with the 2.0 specification. Most full speed devices include lower bandwidth mice, keyboards, printers, and joysticks. The use of high speed USB has exploded with the rapid growth in digital media in the consumer electronics market including media players, digital cameras, external storage and smart phones.

SuperSpeed USB is designator for links operating at the 5 GHz frequency and compatible with the USB 3.0 specification. SuperSpeed USB provides a high performance connection topology for applications that utilize larger files or require higher bandwidth. SuperSpeed USB is backward compatible with USB 2.0, resulting in a seamless transition process for the end user. SuperSpeed USB offers a compelling opportunity for digital imaging and media device vendors to migrate their designs to higher performance USB 3.0 capable interface.

NEC/Renesas was the first chip vendor to introduce host controllers for USB 3.0 (5/18/2009). The first motherboards featuring USB 3.0 ports from Asus and Gigabyte followed in late 2009. In the first half of 2010, dozens of SuperSpeed devices began shipping as vendors rushed to deliver solutions using the 5Gbps signaling speed of USB 3.0. Expect mass adoption into high-bandwidth applications in late 2010.

Why USB?

From its emergence in 1995 as a low-cost connection interface for keyboards and mice, USB has steadily expanded its presence in computing and consumer electronics to become the most popular peripheral interconnect in history. USB continues to be dominant for the following reasons:

  • Mature, proven technology
  • Backward-compatible and low cost
  • Easy plug and play operation
  • Data transfer speeds suitable for a variety of applications

As evidenced by USB popularity, several extensions of the technology have been introduced to try and capitalize on its installed base/ popularity. An example of this extension, which is supported and approved by the USB Implementers Forum (USB-IF), is USB On-The-Go (OTG). Designed to allow portable computing devices, such as cell phones and digital cameras, the ability to connect to other USB devices as either a host or peripheral, OTG promises improved interoperability for an enormous number of USB enabled devices.

In addition, there are now dozens of USB device classes addressing everything from health care systems to isochronous video applications. Mass storage remains one of the most popular USB applications as consumers have embraced all types of digital media. The T10 committee has now finalized USB Attached SCSI (UAS) protocol which enables several significant improvements over legacy mass storage protocols including command queuing and streamed IO. Of particular interest is the new battery charging specification which provides a standard mechanism allowing devices to draw current in excess of the USB specification when connected to wall chargers or fast charging host controllers. In addition to the traditional data interchange application, the battery charging specification has solidified USB's dominant role as the interface of choice in the portable electronics market.

USB Architecture

USB was initially introduced as a host to peripheral interconnect with the goal of putting most of the intelligence on the host-side. The OTG specification added an optional peer-to-peer capability to devices but had limited adoption to date. So the vast majority of USB devices typically fall into 2 categories:

  • Hosts
    • PCs, Macs and laptops
  • Peripherals
    • All devices designed to attach to a host (examples)

The role of the host controller (plus software) is to provide a uniform view of IO systems for all applications software. For the USB IO subsystem in particular, the host manages the dynamic attach and detach of peripherals. It automatically performs the enumeration stage of device initialization which involves communicating with the peripheral to discover the identity of a device driver that it should load, if not already loaded. It also provides device descriptor information that drivers can use enable specific features on the device. Peripherals add functionality to the host system or may be standalone embedded operation. When operating as a USB device, peripherals act are slaves that obey a defined protocol. They must react to requests sent from the host. It's largely the role of PC software to manage device power without user interaction to minimize overall power consumption. The USB 3.0 specification redefines power management to occur at the hardware level with multiple power states designed to reduce power usage across the IO system.

Links

The Advisor T3 is based on Teledyne LeCroy's Voyager analyzer platform with its fast signal-lock and uncompromised 5Gbps recording accuracy. Designed to sit in-line between host and device, the Advisor provides loss-less capture of USB 2.0 or USB 3.0 traffic. Every event is time-stamped including logical state changes and LFPS signals. With its intelligent termination detect mode, the Advisor seamlessly captures in-band reset and hot-plug behaviors between devices.

Hardware Triggering

Hardware-based event triggering is essential for pinpointing protocol events when operating at 5Gbps signaling speed. With the Advisor T3, triggering can be specified at the lowest levels including bus states, ordered sets (U0, SKP, etc…), packet types, or header fields (End of Burst, Packets Pending, etc…). The Advisor analyzer can also filter unwanted traffic from the buffer in real-time by discarding redundant patterns such as SKPs, idles, and training sequences.

Compact and Convenient

The Advisor's unique small form-factor fits within any briefcase yet boasts 2GB of recording memory. The system also offers spool-to-disk capture, making it well suited for testing software drivers or analyzing system performance. Like all Teledyne LeCroy analyzers, the Advisor features field upgradeable firmware allowing the system to evolve with the specifications.

6th Generation Analysis Software

The Advisor T3 provides many of the same features as the Voyager system including the legendary CATC Trace which has become the industry's de facto standard for USB 2.0 protocol analysis. This intuitive hierarchical display can be expanded to show packet level events or collapsed to show complete transfers. A comprehensive tool set is included allowing traffic to be individually searched, grouped, or filtered from the trace.

Key Features
  • CATC Trace Analysis Software System - Expand / Collapse transfers for fast interpretation of USB traffic
  • 2GB Recording Capacity - Capture long recording sessions for analysis and problem solving
  • Raw bit Recording / 10-bit error detection - View and correlate low-level 10-bit symbols to higher-level packet structures

USB Device Decoding

The Advisor T3 software will automatically assign device class decodes using data reported during enumeration by each endpoint. Manual decoding assignment is also available from a drop down menu providing unparalleled support for USB device types. There's full support for the USB OTG specification as well as Video class 2.0, Mass Storage, and USB Attached SCSI (UAS) protocol.

Raw Debugging Power

The Advisor T3 includes the Link Tracker display that captures every transition and presents raw 10-bit data patterns chronologically with timing resolution of 2ns. Designed to assist with low-level debugging, all ordered sets including training sequences and inter-packet symbols can be displayed in 10-bit, 8-bit, scrambled, and unscrambled Hex format. Unlike Pipe-PHY based analyzers that swallow 10 bit symbol errors, the Advisor T3 shows malformed packets, framing errors and invalid codes to allow unambiguous analysis of link problems.

Find the Issues Fast

Traffic summaries provide event metrics for USB 2.0 and 3.0 events within a trace. The Bandwidth calculator automatically generates performance metrics for every endpoint in the trace. The Bus Utilization report graphs packet length, bus usage by device, and throughput in a histogram format.
