+  Power Signal Emulator Node
+
+  Power signal emulator allows executing AP Power Sequence in a virtual
+  environment by simulating power signals behavior.
+
+  This file defines a node to bind two or more power signals. A node connects
+  one input-signal with one or more output-signals. When a node is loaded and
+  initialized by power signal emulator, its input-signal state will control
+  the value of its children output-signals. Behavior of output-signals are
+  configurable to meet AP power sequence test cases.
+
+  Power Signals direction is determined from emulator node perspective. An input
+  signal in a node, is the one to be monitored by the emulator, while an output
+  signal gets its value altered when corresponding input signal's state changes.
