Recording Options
• Versatile triggering: bit-wise value and mask data patterns up to sixteen bytes wide
for Setup transactions and data packets
• Triggering on new High-speed PIDs and split transaction special tokens (ERR,
SPLIT, PING, NYET, DATA2, and MDATA).
• CATC Trace displays and enumerates High-speed Micro Frames.
• Three forms of triggering: Snapshot, Manual, and Event.
• Transaction sequencer: Allows triggering on a token qualified by a data pattern
and/or specific handshake, or can filter transactions (such as NAK’d transactions).
• Advanced triggering with event counting and sequencing
• Dedicated trigger for recording input and output used to interface to external test
equipment
• Triggering on multiple error conditions: PID bad, bit stuffing bad, CRC bad,
end-of-packet bad, babble, activity loss, frame length violation, time-out or
turn-around violation, data toggle violation, Token, Bus Conditions, Data Length,
and excessive empty frames
• Real-time traffic capture filtering and data packet truncation variable up to 256 bytes
• Adjustable buffer size from 0.4 MB to 512 MB
Display Options
• Uses the CATC Trace graphical display of bus packets, transactions,
split transactions, and transfers.
• Groups numerous packets and transactions under a single transfer while quickly
decoding all essential information.
• Decodes split transactions upstream and downstream of a transaction translator
with a special hierarchical view.
• Has reports summarizing key statistics and conditions of interest, with the ability to
jump to the selected item in the trace display.
• Records flexible input signaling with the CATC Trace.
• Uses a Trace Viewer backward compatible with Advisor™, Chief™, Inspector™,
and Detective™ trace files.
• Indicates trigger position by different pre-trigger and post-trigger packet colors.
• Sets markers to assist with navigation and time calculations. Each marker can
contain unique comments.
• Hides start-of-frame (SOF) packets and any packet or transaction.
• Searches for a specific PID.
• Detects, and alerts you to, every potential bus error and protocol violation, and their
combinations.
• Has high-resolution, accurate time stamping of bus packets and timing
measurement and analysis functions.
• Has search and packet hiding capabilities.
• Allows comprehensive device class decoding and user-defined protocol decoding.
