Hi,

I ama getting this error message while running transient sim.

Error found by spectre at time = 1.93594 us during transient analysis `tran'.
ERROR (SPECTRE-16929): Transient analysis is simulating with step size less than 2 as for 1000 steps.
Change option `max_consecutive_minstep' to adjust the allowed maximum number of consecutive steps to be less than 10*MinStep.

May i know what it means and where to set up this option specified in the error message.

Thank you,
mvj
 

Step size less than 2 makes no sense. There should be some unit
(or, you specified a crazy large minimum timestep of 0.2 seconds).

But usually very fine time stepping comes from transient convergence
problems, such as lack of sane capacitances, over-ideal edges,
bistable elements that get "stepped past" and break the iterative
solution process when it tries to dial back.
