2.4.6. Defining Trigger Conditions

By default, the Signal Tap logic analyzer captures data continuously from the signals you specify while the logic analyzer is running. To capture and store only specific signal data, you can specify conditions that trigger the start or stop of data capture. A trigger activates—that is, the logic analyzer stops and displays the data—when the signals you specify reach the trigger conditions that you define.

The Signal Tap logic analyzer allows you to define trigger conditions that range from very simple, such as the rising edge of a single signal, to very complex, involving groups of signals, extra logic, and multiple conditions. Additionally, you can specify Power-Up Triggers to capture data from trigger events occurring immediately after the device enters user-mode after configuration.
