Scicos: Scilab's block diagram modeler/simulator

Scicos is a graphical dynamical system modeler and simulator toolbox included in the Scilab ® engineering and scientific computation software. With Scicos you can create block diagrams to model and simulate the dynamics of hybrid dynamical systems and compile your models into executable code. Scicos is used for signal processing, systems control, queuing systems, and to study physical and biological systems. New extensions allow generation of component based modeling of electrical and hydraulic circuits using the Modelica language.

With Scicos you can:

Graphically model, compile, and simulate dynamical systems

Combine continuous and discrete-time behaviors in the same model

Select model elements from Palettes of standard blocks

Program new blocks in C, Fortran, or Scilab Language

Run simulations in batch mode from Scilab environment

Generate C code from Scicos model using a Code Generator

Run simulations in real time with and real devices using Scicos-HIL

Generate hard real-time control executables with Scicos-RTAI and Scicos-FLEX

Simulate digital communications systems with Scicos-ModNum

Use implicit blocks developed in the Modelica language.
Discover new Scicos capability using additional toolboxes.

2008-4-17 A pool of Scicos diagrams are used to perform automatic testing of new releases of Scicos. Visit our test center. The test results concern the comparison between Scicos versions 4.2 and 4.2.1. The differences in the simulation results of a few diagrams indicate problems in version 4.2 that have been solved in 4.2.1.
