The ATA/ATAPI/UDMA Pod turns the Bus Doctor
into a full-featured protocol analyzer, with the depth, ease-of-use, protocol
decoding, and statistics needed by software and systems testers. The ATA/ATAPI
pod supports both normal and small form-factor connectors.
It provides the features needed by hardware engineers including multi-level
triggering, filtering, state configuration, and timing analysis of PIO,
DMA and UDMA transfers with speed capability exceeding 200MB/s. It supports
ATA/ATAPI 7 as well as the 48-bit LBA addressing of terabyte-plus drives.
It decodes the ATA commands used by hard drives and the ATAPI protocol
used by CD, DVD and Tape devices.
ATA Analyzer DATA SHEET
ATA / ATAPI / UDMA Displays
At the Command level, the ATA/ATAPI analyzer provides a big-picture view
for testers who are troubleshooting system-level or application-level
issues. The State display provides register-level access details for users
who need to monitor ATA/ATAPI software, device drivers or firmware. For
hardware engineers, the Timing Waveform display provides for analysis
of ATA/ATAPI signal activity.
ATA / ATAPI Capturing
The ATA/ATAPI analyzer provides 3 predefined capture configurations:
1. Timing Mode (Store all transitions)
2. State Mode - PIO/DMA/UDMA & HRESET
3. State Mode - PIO/DMA/UDMA & UDMA CRC
Modes 2 and 3 allow the user to decide between using a state to store
Hard Resets or UDMA CRC values. Custom State Modes can also be created.
ATA / ATAPI Triggering
The ATA/ATAPI Analyzer provides high-level trigger configurations for
most common trigger scenarios. The high-level triggers provide drop-down
boxes that enable the user to select specific commands, addresses, etc
from a list, without memorizing opcodes. Users can also create and save
custom triggers.
Triggering is used to stop the trace when a specific event or sequence
of events occur. The analyzer also provides for stopping when the buffer
is full, or looping endlessly until the user manually stops the trace.
High-Level triggering options are provided for each bus. The User can
also create custom triggers using the powerful Trigger Sequencer.
ATA / ATAPI Analyzer Trace Filtering
The ATA/ATAPI Analyzer provides commonly used high-level filter configurations.
Some of the high-level filters provide drop-down boxes for configuration
options. Users can also create and save custom filters.
After capturing, the Show/Hide controls for the Command and State Listings
provide you with a variety of criteria for selection of portions of the
trace to display.
Pre-configured filters for each bus allow the user to conserve buffer
space and reduce the stored data to those items that are of interest.
Custom filters can also be created.
ATA/ATAPI Statistics
The Real-Time Monitor is pre-configured for certain common statistical
measurements, but can be easily reconfigured by the user for almost any
type of measurement desired.
Dedicated hardware is provided for counting events. Software processes
this data providing simple, or ratios of events per time or other events
such as Transfers per Second, Transfers per Command, or Data Transfers
per Error. These ratios are shown as Current Values and Peak Values, providing
a summary of the changes over time.
Protocols, Standards, & Speed
Protocols & Standards:
* ATA ver 1 through ATA/ATAPI 7
* FF8020
* Mt Fuji
* SCSI MMC
Speeds:
* PIO Modes 0-4
* DMA Modes 0-2
* UDMA-33 to UDMA-133
PROTOCOLS
The analyzer decodes many of the high-level protocols that are transmitted
on each bus. The Command Listing is typically used for displaying high-level
protocols which may be transferred across a bus, while the State Listing
typically displays native, low-level protocols.
