6-4 Timing: Introduction
Trace memory can store 1010 trace states if the standard mode is
used or 505 states if the glitch capture mode is used.
The trace specification allows you to define the trigger condition
about which trace states are captured. The trigger specification can
be defined on transitions of signals, levels of signals, or glitches on
signals. The trace memory can be positioned anywhere about the
trigger condition or after the trigger condition by a specified
amount of time.
The format specification defines the labels which are to be
associated with the probe signals along with the logical polarity of
the signal. The format specification also defines the threshold
values to be used during the capture of trace memory.
The post processing specification defines the analysis to be done on
each set of sampled data. It enhances productivity by reducing the
amount of time needed to make a range of computations about the
trace memory. There are features to find, mark, compare, and
gather statistics about events occurring in trace memory. In
