    Error voltage failed to converge Reply

    Hello.

     

    I'm doing a simulation with Capture and it is aborted showing the next message:

     These supply currents failed to converge:

        I(X_U7.L_L2)              =   -1.70575e-006 / -1.15349e-006

        I(X_U10.L_L2)             =    3.83095e-007 / 1.52301e-008

        I(X_U7.V_V5)              =   -1.70575e-006 / -1.15349e-006

        I(X_U10.V_V5)             =    3.83095e-007 / 1.52301e-008

     As we can see, the fail appears in the 7th decimal number, that is an accuracy error that I can accept as valid.

    Is there any option setting that could let me continue jumping over this error? 

    If you need more info, please let me know. 

    thank you so much.

    you may want to try changing following two simulator parameters

    set ABSTOL=1n

    set ITL4=40

    you can access these from PSpice > Edit Simulation Profile > Options TAB > Select Analog Simulation

    See if these changes help you overcome above. I assume you are getting these errors in Transient analysis?

    The problem has been solved. It worked!!

     Yes, the problem was in transient analysis.

    Thank you very much!
