A Debug / Single Step mode would be useful. Stepping could be in terms of individual actor firing, micro step increment or model time increment. When paused in debug mode, it should be possible to see which ports have tokens on them, and what those tokens are.

There is a debugger, it was originally started by Frederic Boulanger of Supelec and then worked on by Elaine Cheong. The debugger currently only works in SDF, and is accessible by right clicking on an actor and selecting "Set Breakpoints"

There was some internal traffic about extending the debugger to DE at http://chess.eecs.berkeley.edu/ptolemy/listinfo/ptolemy/2006-December/009724.html

This enhancement has a few parts:

• Extend the debugger to other domains, particularly DE. In DE the stop time would be model time.
• Allow inspection of data on ports.
