howdy.   i'm a new subscriber to these mailing lists, so forgive
        (and educate) me if my notions have been discussed here before.

        this may be to far fetched, but, having written many waveform
        viewers, a really, really usefull feature would be to have
        the waveform viewer linked to the simulator in such a fashion
        that the .raw (or .tr0) file could contain restartable snapshots
        of the simulation.  then, when the waveform viewer attempts
        to use data between these restartable snapshots, the linked in
        simulator starts back up and provides the intermediate data,
        via resimulation from the most immediate previous snapshot.

        this allows the .raw file to be much, much smaller for large
        simulations (eg, a 24hr pll simulation may be otherwise unviewable
        if all data is retained), and potentially speeds up viewing of
        long simulation results dramatically.

        of course, to minimize problems with subsequent changes to
        the simulator, or input data, both the simulator, and the
        entire simulation input deck need to be captured, preferably
        in the (monolithic) results file.  call this ~4mby.

        this would be a small price to pay for simulation results files
        that would otherwise be intractably large.

        lastly, such a mechanism would want to be explictly enabled
        by the user, otherwise maintaining todays current results
        paradigm.

        thanks for listening.
