Modified by dietmarw on 1 Mar 2010 06:26 UTC There wasn't a ticket on this yet...

From [milestone:Design63]

Status: Test implementation in Dymola Short Description: Introduce new operators Connections.uniqueRoot and uniqueRootIndices to describe undirected graphs in Modelica where the Modelica tool guarantees certain properties. This allows to implement in a rather simple way hierarchical state diagrams (similar to Statechart) that are “safe” in the sense that only correct graph structures can be constructed (otherwise a tool can give immediate diagnostic). Details see

Comment by HansOlsson on 15 Sep 2010 14:47 UTC A different handling of state machines is planned for Modelica 4 - using native language element describing state machines.
