More specific ...  combining some mails ...
-- info I left out of the previous message.

The required time step is 6.11037e-17 .

You said (by specifying option dtmin) that the smallest 
acceptable time step is 1e-16 .

The action taken by the simulator is to switch that device to 
Euler and not use it for step control.

I need to reword that message.

How would you like something of the form ...
C567: is too fast
Required step for accuracy: 5.58e-18
Min step per option dtmin:  1e-15
Using Euler for this device.

Eventually, the plan is to accept the full set of choices that 
Spectre offers.  To much to do, too little time.

Then you could say "method= traponly" or "method=trapeuler", and 
have more control of it.
