Interesting. As part of an ESPRIT project, I've been producing a compiler
for the Function Block graphical language described by IEC1131-3 (the
project has also produced an X-based editor for writing such programs). In
addition to producing code for a fictitious industrial controller, the
compiler generates C which can be used for simulation. I've found that
the most rewarding means of providing this simulation to be to use the
generated C to implement a new Tcl/Tk command, "iec_scan", which performs
forcing of inputs, execution of a single scan of the program, and monitoring
of outputs. This method makes it *really* easy to produce an impressive
simulation.
