This environment, developed at IRISA with the support of the CNET, allows the user to have graphical and textual representations of the language structures. These representations may be used together during the building or the "reading" of the programm. A SIGNAL expression may be considered as a set of components (represented as boxes) with connection points (ports represented with triangles) joined by links (a succession of connex segments). The same SIGNAL expression is also a system of equations on series of values; this system is represented by a phrase built with t...
