Demux

Demux SimObject that takes a vector as input and splits it into several output ports.

Collaboration diagram for Demux:

A demux (or demultiplexer) is a device taking a single input signal and selecting one of many data-output-lines, which is connected to the single input. The sum of all output port sizes must be equal to the input port size. Implementation class is CDemux.

A figure illustrating the principles of demultiplexing.
