A palette browser lists all Xcos standard blocks grouped by categories (signal processing, electrical, hydraulics, derivative, integral, etc.).
Compiler / Simulator
Xcos environment enables, from the built model, the simulation of complex systems - discrete, continuous, defined by symbolic equations (Modelica), etc.. and hybrid systems combining the capabilities above. The data resulting of the simulation can then be graphically viewed in real time, used in Scilab for post processing...
