Resource Terms
Resource terms are user-defined variables that are assigned to
sequence levels. They are placed into the sequence statement where
their bit pattern or edge type is searched for within the data stream.
When a match is found, a branch is initiated and the next statement or
sequence level is acted upon. Resource terms take the following
forms:
•
Bit Patterns Terms a
−
j
•
Range Terms 1 and 2
•
Edge Terms 1 and 2 (Timing only)
Bit Patterns Terms a
−
j
When the logic analyzer is configured as a state analyzer, up to twelve
resource terms can be assigned in your trigger specification. You can
use any of the 10 bit pattern terms a
−
j, plus any of the two range
terms 1 and 2.
When the logic analyzer is configured as a timing analyzer, up to ten
resource terms can be assigned in your trigger specification. You can
use any of the 10 bit pattern terms a
−
j, and any of the two edge
terms 1 and 2 as long as the total does not exceed ten.
Bit patterns terms can also take the NOTed form of
≠
a
− ≠
j.
Range Terms 1 and 2
Two range terms are available which can be set to a range of bit
pattern values. The first pattern and the last pattern are part of the
range which must be matched.
Range terms take the form of either In Range, or the NOTed form of
Out Range.
