Hi everybody, I would like to write a hierarchical Model following this description: -->Model of Computation for the Top Level: PN Domain; -->Models of Computation for Sub Levels: SDF Domains. I have some trouble implementing & simulating such a model. Is their any Limitation in Domain Interoperability ? Thanks in advance for your enlightened answers. -- Stéphane Pulon Software Engineer I.B.T.C Thales Underwater Systems France ---------------------------------------------------------------------------- Posted to the ptolemy-hackers mailing list.
