Error clarification


I’m getting the following error when I run a simulation:

can’t read “total vstep” : no such variable while executing

“expr $total_vstep” (file “apps/omenwire/r91/rappture/omenwirewr” line 1)

Could you please explain to me what this error means?

I’m applying a minimum gate voltage of -0.6V and maximum of 0V.

Thank you.

    Hi, I actually got results, but it seems that simulation had some convergence problem, which means that the convergence criterion is hardly met and the results don’t seem to be right. Let me further assist you if you really need to simulate this structure. My e-mail address is and please tell me why you are doing this simulation and what the analytical(or qualitative) solution looks like.

    Thank you for your question, but I couldn’t duplicate the situation. Could you tell me what other parameter you changed from the default?
