   Ok, I know, better replace spice with: nonlinear differetial
   equation solver.

   It needn't be SPICE if there's something better. 

Right, SPICE isn't the only simulator, but just as an example and
point of reference, SPICE would fail completely at this task.  So
another simulation approach would be required, one designed and
tweaked specifically for the task at hand.  It would have to work a
lot better than SPICE.  That would require some research.

The fact that the Z-plane is so different from the S-plane is a great
example of how the simplist of operations, linear integration, gets
complicated when you try to simulate it.
