Modelling bus switches and other series elements

Good morning,

Maybe instead of a syntax that defines all possible connections
simultaneously (making it look like there are many simultaneous
paths) we should find one that clearly calls out the different
switch states. Something like:

[State] StateName1
| Pin Pin Model
   1 3 SMC

[State] StateName2
| Pin Pin Model
    1 5 SMCx

I'm not suggesting this as the actual syntax, only as an example
to explain my concept. The simulator must be told witch state of
the switch to use in any particular simulation.

Of course, if the goal is to model the transition between states
this is not helpful. However, users of our system have not asked
for that capability, but they have done things like Richard Mellitz
suggests, swapping out one model for another, manually.

This syntax would give the user a way to specify the different
switch states. It would be up to the simulator to allow the
user to specify whitch state to use when.

The same, or a degenerate syntax without the [State] specified
could be used for series elements that are not switchable.
