+title: Trigger Generation Unit - TGU
+
+description: |
+  The Trigger Generation Unit (TGU) is a Data Engine which can be utilized
+  to sense a plurality of signals and create a trigger into the CTI or
+  generate interrupts to processors. The TGU is like the trigger circuit
+  of a Logic Analyzer. The corresponding trigger logic can be realized by
+  configuring the conditions for each step after sensing the signal.
+  Once setup and enabled, it will observe sense inputs and based upon
+  the activity of those inputs, even over clock cycles, may detect a
+  preprogrammed state/sequence and then produce a trigger or interrupt.
+
+  The primary use case of the TGU is to detect patterns or sequences on a
+  given set of signals within some region to identify the issue in time
+  once there is abnormal behavior in the subsystem.
