Terminate unconnected output port
Use the Terminator block to cap blocks whose output ports do not connect to other blocks. If you run a simulation with blocks having unconnected output ports, Simulink® issues warning messages. Using Terminator blocks to cap those blocks helps prevent warning messages.
The Terminator block accepts real or complex signals of any data type that Simulink supports, including fixed-point and enumerated data types.
For more information, see Data Types Supported by Simulink in the Simulink documentation.
The following Simulink examples show how to use the Terminator block:
Inherited from the driving block
