Logic Analyzer Concepts
The Trigger Sequence
Analyzer resources
The sequence-advance, sequence-else, storage, and trigger-on 
specifications are set by a combination of a maximum of 10 pattern 
terms, 2 range terms, 2 timers, and 2 edge terms (for the timing 
analyzer only). A resource can only be assigned to one analyzer at a 
time.
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, or both the 
address and status occurring together. Pattern terms AND conditions 
occurring on separate labels. 
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."
2 edge terms (timing analyzer only). The edge terms, Edge1 and 
Edge2, represent edges. The edge terms can be set to catch glitches 
even when the timing analyzer is not in glitch mode. When an edge 
term comprises more than one channel, it ORs the channel conditions 
together and any of the specified transitions satisfy the term.
