Communications Blockset

Other Blocks

The Terminator and Info blocks do not perform a function during the simulation, yet they serve other purposes.

Terminator Blocks

The Terminator blocks, from Simulink's Signals & Systems library, attach to output ports whose signals are not used in the rest of the model. Simulink warns you if it finds an output port that is not attached to another block. Terminator blocks prevent warnings from occurring.

Info Block

The block marked "Info" is a customized version of Simulink's Model Info block. It is customized so that double-clicking on it displays the HTML version of this documentation in the Help browser.
