BENEFITS
• Hardware search logic makes it possible to find a CE-ATA or MMC event in seconds
• Field serviceable interposer boards with ZIF connectors for CE-ATA and MMC connectors for native MMC
• Logic analysis in addition to protocol analysis in the same Bus Doctor; having these two critical functions in one compact unit save both valuable desktop space and money
• One interface for all bus types means learn a single GUI for testing all bus types supported by Finisar Bus Doctor Analyzers including CE-ATA, ATA, SCSI, SATA, Firewire
(IEEE1394), Cardbus, Compact
Flash, PCMCIA, PCI/X and USB
• The RX may be combined with other RX Analyzers to perform multi- analysis on several buses simultaneously to ensure interoperability between multiple bus types
According to a recent Gartner/Dataquest report, shipments of sub 1 inch drives for non-PC markets are expected to grow from 40 million units in 2005 to 146 million units by 2009. The application areas fueling this growth are digital media players, digital recorders, digital audio players such as the wildly popular iPod from Apple Computers, multi-media cellular phones such as the recently ones developed by leading mobile telephone manufacturers.
CE-ATA is a new storage protocol initiated by the CE-ATA standard committee to address this new emerging market. Utilizing the proven MMC physical interface and a subset of the ATA protocol, CE-ATA is optimized for mobile power and performance; these are factors critical in mobile consumer electronic applications.
Without a CE-ATA protocol analyzer, storage, silicon and design engineers will find working with this new storage technology challenging.
PRODUCT DESCRIPTION
The Bus Doctor™ RX from Finisar is a powerful modular, consumer electronics bus protocol analyzer. With advanced features such as trace buffers as large as 4.6 GBs and 4 nanosecond capture resolution, the RX is a unique platform able to analyze CE-ATA technology as well as other consumer electronic and computing protocols.
By connecting a MC (Memory Card) Pod fitted with an ZIF-based interposer board to a CE-ATA system consisting of a host and drive, the RX becomes a dedicated CE-ATA protocol analyzer (the industry’s first CE-ATA protocol analyzer). The analyzer operates at the MMC and CE-ATA bus widths of x1, x4 and x8 and supports filtering, capturing and triggering of MMC and CE- ATA events.
The analyzer is controlled by a Microsoft Windows™ PC through a USB connection; Finisar’s powerful, yet simple to use, Bus Doctor Graphical User Interface (GUI) CE 4.0 software runs on the PC (see Figure 2). The software provides an easy-to-use interface that allows engineers to configure the instrument and to view and analyze captured CE-ATA or MMC data.
High-level dialogs provide for the quick creation of powerful triggers and pre- and post-capture filters (see Figure 3). These filters allow engineers to home in, and capture and analyze only those events and sequences of interest. As an example, one can filter on a CE-ATA or MMC command either the host to device or device to host direction.
The powerful trigger sequencer has 12 levels, including 2 timer and 2 counter levels. This allows for triggering on various MMCor CE-ATA events (see Figure 4). Triggers may also be setup for a variety of hardware and software errors.
Once data is captured, the software simplifies analysis by organizing and grouping the captured bus data into different displays. Command sequences are summarized in the command listing n display.
The State Listing o displays a chronological list of all captured events. For each event, this display shows the Store #, Command Count, Command Data, Command Description, Response Count, Response Data, Response Description and the Timestamp.
The Timing Waveform p shows a signal level representation of the trace, each row representing a channel or channel group.
The user may reorder the rows or change thecolors according as desired. Data maybe displayed in hex, decimal, binary or ASCII formats.
The histogram’s q primary purpose is a navigation aid, showing an overall map view of the entire trace. Commands, data, and errors are shown in blue, green, and red, respectively. A User Term can be defined and is shown in purple (see Figure 5).
The Bus Doctor CE-ATA analyzer supports MMC and CE-ATA bus widths of x1, x4 and x8. The Bus Doctor analyzer is also available in three configurations: SLIM, FIT and BUFF. These models have capture buffers of 16, 64 and 256 million events respectively; a 256 million event buffer translates to over 4.6 GBs of physical memory.
Two types of interposer boards come standard with the MC pod: one with ZIF connectors for connection to CE-ATA hosts and devices and one with MMC connectors for tapping and use with native MMC host and devices.
In addition, the MC pod can be used in conjunction with a Bus Doctor Logic Pod(future capability), providing both protocol and logic analysis functionality under one platform.
And there are provisions to support other media card formats including SD (future capability) and Memory Stick (future capability).
The Finisar Bus Doctor CE-ATA protocol analyzer delivers the tool to analyzw and debug MMC and CE-ATA technologies.
