Description

Splits a vector into its signals, in order: the counterpart of Mux.

Set the number of outputs (2 to 32) under Signals in the block’s properties. The input is cut into that many equal parts, so with 6 signals and 2 outputs each output is itself a vector of 3. Match incoming sets the outputs to one per signal.

Example

Mux and Demux Three signals carried across the sheet on one vector wire, then split apart again.

In Gradara, select a Demux block and press F1, then choose Open example. It opens as a new model in My models, ready to run.

Also in this example:Sum Constant Ramp Sine wave Mux

Ports

Inputs 1

usignal

A vector, usually from a Mux.

Outputs 3

1y1signal

The first part of u.
2y2signal

The second part of u.
3y3signal

The third part of u.

Equations

Modelica

y1 = u[1], y2 = u[2], y3 = u[3]  (with one signal per output)

Implementation

The block’s Modelica model

y1 = u[1];
y2 = u[2];
y3 = u[3];

Assumptions and limitations

The number of outputs must divide the width of the input; otherwise model checks report it.
The parts are equal in size; to take signals by name, bundle them with a Bus Creator and use a Bus Selector.
