Scicos: Block diagram modeler/simulator

Scicos  is a graphical dynamical system modeler and simulator developed in the Metalau project at  INRIA,  Paris-Rocquencourt center. With Scicos, user can create block diagrams to model and simulate the dynamics of hybrid dynamical systems and compile 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
• Use implicit blocks developed in  the Modelica language.
• Discover new Scicos capability using additional toolboxes.

2011-4-8 Scicos 4.4.1  has been released. Packages for Windows, Linux and Mac platforms are available  here. This release is mainly a bug fixing release, however there have been some new additions and improvements wrt to Scicos 4.4. In particular, the Coselica toolbox is now included in the package. The  Coselica toolbox, developed by Dr. Dirk Reusch, provides a large number of Modelica blocks for the Scicos environment.  
Some improvements in Scicos are:

- Improved scope performance under Linux and some stability issues fixed under Windows.  
- More facilities to manipulate masks: it is now possible to restore a removed mask.
- More blocks accept integer datatype input/outputs and scalable initial conditions.
- Annotations (text of TEXT block) can now be multiline.

A number of reported bugs have also been fixed, in particular two serious bugs in the integral and 1/z blocks.

Scicos 4.4 is a major release. It includes many improvements and some new functionality. Major changes concern the code generator, the simulator and some important blocks. Here is a partial list of changes with respect to Scicos 4.3:  

Graphical editor:  Improved block dialog boxes with XML import/export, addition of Bus links (experimental for the moment), introduction of new facilities for constructing nice diagrams (automatic adjustment of block locations to obtain horizontal and vertical links, gridding), addition of an option to use fixed size fonts in block icons to obtain a more uniform look, and bug corrections in particular in the Masking and Atomic operations.  
Scicos/Modelica compilers:  Better integration of the latest version of the Modelica compiler and some minor bug corrections in the Scicos compiler. In this version, the Scicos compiler can also call the interfacing functions of Scicos and Modelica blocks with the job 'compile' during the compilation process to improve checks/sets of some block parameters (like input/output sizes and types...)  
Simulator:  Important architectural changes and the addition of a new solver.  
Code Generator:  It includes major improvements allowing in particular its application to models with asynchronous dynamics and Modelica components. Its usage via the Atomic operation allows separate compilation of non-directly-communicating Modelica parts within the same Scicos diagram. Default properties of the code generator for each Super block can now be set using a GUI. Standalone code generation now works for all Scicos diagrams (except for diagrams that use Scilab blocks) including diagrams with continuous-time dynamics requiring ODE/DAE solvers.  
Library of blocks:  A new palette (Iterators) has been added and many improvements have been made in existing blocks, in particular the delay blocks and the scopes. The main scope blocks can now function by inheritance in most situations so their activation input port is no longer present by default. An interactively editable Scilab block of type 5 has been added.  
Modelica initialization tool:  The graphical interface has been improved and additional numerical solvers are used.  

2009-9-26   RTSS 1.0.0 - A new release of the Robotics Toolbox for Scilab/Scicos is now available for  download. RTSS is intended for modeling and simulation of robotic manipulators in the Scilab/Scicos environment and has been developed at Centro "E. Piaggio" by Matteo Morelli. See the  official announcement  for more details.
