In my model, a variable resistor is serially connected to the current source with a ramping variation (see the inserted fig1).
The resistance of resistor has the ultra non-linear relationship with the current (see the inserted fig2).
When tthe model runs to 0.0085 seconds, four errors (see the inserted fig2) interrupt routine running. How could I solve the "Description ERROR: Abnormal termination of EMTDC by ITRIANG"? Thanks for any comments.
