Simulation of model as a system

[dfricker]

I am new to EA so please forgive me if I am asking a ridiculous question! However I cannot find much documentation around this area.
I am evaluating EA to find out how effective it is at simulating the behaviour defined within a model. I have done similar tasks with Rhapsody before (i.e. animating statecharts and auto generating sequence diagrams). So far within EA all I have figured out how to do it simulate a single statechart, is there a way in which the entire model/system can be simulated (and from which the information flow between the classes can be shown on a sequence diagram, rather than what appears to be a strange mixture of elements shown on an EA sequence diagram generated from a stack trace?!)? I'm not sure if this is the intended use for EA, seeing as it seems to simulate on the fly using javascript rather than building the model from source and simulating that instead?
I also notice that if a statechart is added to a class, the transitions, guards and effects are not likely to compile when the source class is generated, therefore building the source generated form EA and deploying to a target is not likely to be possible?
Thanks for any clarification you can provide.
