[755-1] Updating Accusim viewpoints

[Konstantinos Dovrolis <dovrolis@cs.wisc.edu>]

Another note from Ross, this time for updating an Accusim
viewpoint with changes that have been done in the schematic,
after the viewpoint was created:

> Edit the schematic in DA then in accusim choose 
> File->design->load DA changes
> this will update the viewpoint to the newest version of DA
> files. Unfortunately if you have a trace open when you do this the
> next time you click on run it crashes accusim. I have not yet tried
> closing the trace, loading changed, creating a new trace and then
> running. However choosing 
> File->simulation->SAVE|setup files only
> means that you can then load them and not have to reenter the accusim
> libraries and force files. What does work is simulating in accusim,
> saving setup, modifying DA, quitting accusim, opening accusim, loading
> setup files, loading DA changes, then trace and run.
