| Timing
Display
The timing display represents trace data as waveforms for timing
analysis. A numeric value is provided on top of each waveform. As in the
state display, signals can be moved, inserted, deleted and color and radix
defined. Grouped signals such as address can be collapsed and expanded and
their range specified. A zoom is provided to get a better look at waveform
relationships.
Sampling
The PCI850 has a precision oscillator used to sample the bus at
periodic intervals for timing analysis. The sample rate is selected by the
user. |
Time
Measurements
Cursors can be placed on the timing and state display to measure time
between the trigger and a cursor and the time between 2 cursors. Times are
shown at the top of the display and in the trace window.
Status Indicators
At the top of the display a status indicator shows the number of
samples captured before and after the trigger and the current state of the
analyzer.
Capture Control
GO and STOP icons control when tracing starts and halts. |
Setup Wizard
To assist in setting up the analyzer for state and timing analysis a
Setup Wizard automatically programs the analyzer based on what the user
wants to look at. Once a setup is defined it can be saved and later
loaded. |
