4 Operation
Add window
A powerful feature of the VBT-325 firmware is the ability to add other trace
windows, either as alphanumeric trace lists, or as waveform displays. The
windows may be considered completely independent from each other. Different
parts of a trace may be shown in each window, and scrolling in one window
takes place without affecting another etc.
Refer to the Window command in the COMMANDS REFERENCE chapter
later in this manual, and trace examples in the following chapter to see how
different trace windows can be used.
Trace Dump to PC/Host
Trace buffer data can be dumped to a file on a PC. The file format contains a
header with Target type, Sampling mode, Trigger position, Trigger line number
etc, so that the file can be reviewed exactly as captured. You can use the PC
Simulator (see below), or load the file back into the VBT-325. Partial traces
can also be dumped, and packing can be used to reduce transfer time. A user
comment can be added to the file, this can be read by using the DOS command
type < f i l e n a m e > .
Simulator used for trace review
The simulator, which runs under DOS, is a true representation of the firmware
of the VBT-325. This is supplied on a diskette free of charge with each shipped
VBT-325 product. The simulator is extremely useful for reviewing trace files
captured by the analyzer and dumped to a file on a PC. (Ref. ch. SIMULATOR
at the end of this manual.)
(For users of the STIM200-PB, the simulator may be very useful for creating
patterns locally on the PC, and when a good pattern file is made, it can be
loaded into the STIM200-PB itself for execution. Ref. STIM200-PB User's
Manual.)
Statistics
The VBT-325 provides powerful statistical measurements of target bus activity.
Firmware Version 4.99.120 implements three functions, including:
• E v e n t Counting, incl. Bus Level Histogram (counter driven)
• B u s Utilization Histogram (counter driven).
• B u s Transfer Rate Histogram (trace driven).
