How can I create a subsystem which performs the opposite of the Multiport Switch block?

I would like to create a subsystem which performs the opposite task of the Multiport Switch block. I would like the subsystem to pass a signal to one of several outputs based on a second input.

Answer 1

[MathWorks Support Team]

It is possible to create a subsystem which performs the opposite task of the Multiport Switch block using some basic blocks from the Simulink block library. An example is attached which demonstrates one possible way to create this subsystem.

What output do you expect for each of these output signals in HDL?

Say you have 10 outputs, your input is 1, and you want to send this to output 10, what do you expect to send out to outputs 1-9?

Answer 3

[Kiran Kintali]

function [y1, y2, y3] = fcn(u, sel)

y1 = 0;
y2 = 0;
y3 = 0;

switch sel
    case 1
        y1 = u + 1;
    case 2
        y2 = u * 2;
    otherwise
        y3 = u;
end

Can you provide a piece of MATLAB pseudo-code to describe your problem?

I am sure we can help you make it work in the MATLAB function block and generate HDL code from it.
