Octave-Scilab co-simulation package

Toolbox provides the functions for variable exchange between Octave and Scilab workspaces, and for the remote commands execution in Scilab, such as starting xcos simulation. The main goal of this toolbox is to make an alternative for Simulink in Octave from Scilab xcos. But it can be also used to uses functions from Scilab toolboxes, that are unavailable for Octave.


1. Install Octave version 4.0.0 or higher and Scilab v.5.5.2 or higher

2. Install sockets package in Octave by executing

pkg install -forge -auto sockets

3. Download sci_cosim package from

4. Install sci_cosim package in Octave by executing

pkg install -auto sci_cosim_0.1.2.tar.gz

5. Start Scilab GUI and install Toolbox Backdoor by pressing in main menu Applications → Module manager - ATOMS → Technical → Backdoor → Install

6. Restart Scilab. If every thing was done correct, after restart there will message in command window "BackDoor: listening to connections on TCP port"

Running demo

1. Download demo from

2. Extract it to any folder, where your user has read/write rights

3. Run Scilab. It doesn't matter for the co-simulation package if you are using GUI version (scilab) or console one (scilab-adv-cli).

4. Run Octave and change folder to the one, where you have extracted demo

5. Run sci_sim_example.m
