How about the ACS event-driven transient simulation core?
In ACS, all devices have a "review" function that is called after
convergence, on deciding whether to accept a time step. It returns a
suggestion for a preferred value for the next step, and can force an
exact time in the event queue.
Back to the switch .......
ACS has a voltage controlled resistor, which can have a nonlinear or
time dependent transfer characteristic. I think this is a better
way. An ordinary resistor can be time dependent, or nonlinear using
source-like functions.
A future version will be able to make components nonlinear AND time
dependent, using 2 dimensional tables, and there will be a "trigger"
element to get it going. This is a very high priority because I need
it for IBIS support.
