you want to capture activity after the trigger is captured, define an
additional sequence level and specify the desired storage qualification
for post-trigger activity (for example, store “anystate”).
Analyzer Resources
The sequence-advance, sequence-else, storage, and trigger-on
specifications are set by a combination of up to 10 pattern terms, 2
range terms, and 2 timers. Different analyzer models may vary in the
number of resources available.
10 Pattern Terms
The pattern terms, a through j, represent single states to be found on
labeled sets of bits. For example, you could have an address on the
address bits or a status on the status bits.
2 Timers
You can start, stop, continue, or pause the timers upon entry to a
sequence state, then use a comparison of current timer value against a
preset value to determine whether to branch to another state.
2 Range Terms
The range terms, Range1 and Range2, represent ranges of values to be
found on labeled sets of bits. For example, you could have a range of
addresses to be found on the address bus or a range of data values to
be found on the data bus. Range terms are satisfied by any value
within the range for “In_Range,” and any value outside the range for
“Out_Range.”
You can combine the pattern terms and range terms with logical
operators to form complex pattern expressions in the
sequence-advance, sequence-else, and TRIGGER on specifications.

Find "." AND and
