Each probe input is connected to a trigger comparator that is capable of performing various operations. At run time the comparator can be set to perform = or != comparisons. This includes matching level patterns, such as X0XX101. It also includes detecting edge transitions such as rising edge (R), falling edge (F), either edge (B), or no transition (N). The trigger comparator can perform more complex comparisons, including >, <, ≥, and ≤.
Important: The comparator is set at run time through the
Vivado®
logic analyzer.
