In Ptolemy, different Models of Computations interact in a heirarchical way
through wormholes. BUt in certain cases this creates a problem. In the
Discrete Event domain, if the firing of the entire system depends on the
firing of a SDF wormhole, then a dummy DE clock had to be used to fire the SDF
source-wormhole so that the rest of the system could fire. This is a very
unitutive way of using a SDF Galaxy to fire a DE system. This was studied and
modified so that the SDF source-wormhole can schedule the future firings of
the galaxy without requiring a dummy clock to fire it.
Interaction of different models of computations is being studied under the
Ptolemy framework, in the context of a voice mail pager. This experience is
being used in the redesign of Ptolemy in Java.
