Per chi non lo conoscesse sul sito :
tams-www.informatik.uni-hamburg.de/applets/hades/webdemos/in...
e' disponibile un applicativo chiamato Hades, sviluppato dall'universita' di Amburgo (ma sito in inglese) , che ho trovato utile per verificare in "real time" un circuito digitale anche complesso.E' completamente free e non sembra avere limitazioni di alcun genere.
Una breve descrizione che potete trovare sul sito stesso:
"What is Hades?
Hades is a framework for interactive discrete-event and object-oriented simulation written in Java. It consists of:
-a simulation engine (actually several different simulators).
-an interactive graphical editor.
tools for visualization (e.g. glow-mode).
-a library of simulation components (e.g. digital logic gates, flipflops, memories, microprocessors).
-a library and design browser.
-a waveform viewer to trace signals.
-a Jython scripting interface.
The main feature of the Hades editor is interactive simulation: the current circuit system can be edited even while a simulation is running. There is no need for the traditional and tedious edit-compile-simulate-analyze cycle.
Written in Java, the software is fully object-oriented and can be used also as an applet embedded in web-pages."
