    AMS simulation taking very small step sizes. Help in finding offending connect modules? Reply

     Hi folks, i have a problem where i'm running a transient simulation regression in AMS. I randomise my supply ramp and on very slow ramps my simulation is taking very small step sizes. (time never advances).

    In order to try and find the problem, i'm running with the -profile option in AMS and i have "warnminstep" set to 1e-12 in the transient options.

    During my simulation at the point where time stops increasing, i get the following:

     "Warning: LTE requirements are forcing the step size below warminstep=1e-12 at time ..."

    The problem is that this warning isn't particularly good for helping to find the offending connect modules.

     Can anyone help? 

    Thank you in advance.
