I think that what's going on in your model is that when the output of the ContinuousClock goes to 1, the ModalModel starts switching states without letting time advance any further. This is the right behavior under CT semantics, since the guard on both transitions is "trigger == 1", and hence when the trigger input has value 1, both guards are true. Your model specifies an infinite number of state transitions in zero time.
In the attached model, I made the following changes: - changed the outside director to DEDirector - removed the inside director - changed the ContinuousClock to Clock - changed the directorClass parameter of the ModalModel to ptolemy.domains.fsm.kernel.FSMDirector (note that this would have been the default if you had first used the ModalModel with DEDirector). - set the synchronizeToRealTime parameter of the director to true. I think you really want DE, not CT for this type of model. CT is useful when you have continuous dynamics (given by ordinary differential equations). It has much more subtle semantics that cleanly support hybrid systems (mixing continuous dynamics with discrete dynamics). Your model, in fact, is a hybrid system with Zeno behavior. See: http://ptolemy.eecs.berkeley.edu/publications/papers/05/OperationalSemantics/ DE is much simpler. In the attached model, each time the Clock generates an output, the ModalModel executes one transition. Replace the Clock with PoissonClock and you get a much more interesting model with random behavior... Hope this helps. Edward At 03:06 PM 4/21/2006, Lutz, Charles D wrote:
