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.
