1394a (Firewire) Pod for Bus Doctor Analyzer

The 1394 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 1394a pod supports asynchronous and isochronous transfers, decodes the AV/C and SBP-2 (SCSI) protocols and provides a topology display.



It provides the features needed by hardware engineers including multi-level triggering, filtering, state configuration and timing analysis of 1394/FireWire transfers.



1394a Displays
The Command Listing provides a view at the Packet level, the 1394/FireWire analyzer provides a big-picture view for testers who are troubleshooting system-level or application-level issues. The State Listing display provides byte-level access details for users who need to monitor 1394 software, device drivers or firmware. For hardware engineers, the Timing Waveform display provides for analysis of 1394 Link Signal activity. It features 3 different 1394 ports for easy connection and acts as a repeater on the bus.



1394a Capturing
The 1394 analyzer provides both timing modes and state modes. In state mode, the capture can be configured to include:
1. Async Packets
2. Broadcast Packets (cycle starts)
3. Isoch Packets
4. Bus Reset
5. Arb Gaps
6. Sub Gaps
7. Ack Packets
8. Node ID
Custom State Modes can also be created.

CAPTURING

The BusDoctor's Capture Engine pushes protocol recording to new limits with the following features:
- Transitional Timestamping
- Bandwidth - 4.5 Gbytes/sec
- Depth - Stores up to 4 Gbytes
- Segmentable Trace Buffer





1394a Triggering
The 1394 Analyzer provides high-level trigger configurations for most common triggering scenarios. The high-level triggers provide drop-down boxes that enable the user to select specific Tcodes, Commands, Addresses, etc. from a list without memorizing codes or positions. Users can also create and save custom triggers.

TRIGGERING

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.

1394a Analyzer Trace Filtering
The 1394 Analyzer provides commonly used high-level filter configurations. Some of the high-level filters provide drop-down boxes for configuration options. Options include: storing the first quadlets only, a specific Dest ID only, or a specific channel only. Users can also create and save custom filters.

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.

1394a Statistics
The Real-Time Monitor can be easily configured by the user for almost any type of Statistical or Bit Error Rate 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:
* 1394-1995
* 1394a
* SBP-2 SCSI Commands
* AV/C Commands
Speeds:
* 100-400Mb/sec

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.
