[IBIS] maximum current flows

Dear ALL,

 

Recently, I have faced the maximumcurrent flows warning. Do anyone know what actual the main cause?

 

I suspect is the R package/ R _pin value that is too small. I try to replace some larger value

and simulate again. I found that the problems gone. Is it that mean the problem cause by the R?

 

Below are the message the shown after use ibischk3.

Any comments on this?
