no output characteristics computed for pnp transistors

It appears that the simulator fails to converge for the standard pnp input deck. It does not provide a proper output characteristic

    Hi Please note that in the tool necessary adjustments would be needed to run pnp type bjt transistor in active mode and to get the required outputs. If we inject +ve current in PNP base and apply -ve base voltage simulation would not converge.

    Here is a sample input deck for studying PNP type BJT.


    Set the doping type=PNP Operation Mode=CE rest unchanged
    Gummel Plot, Vc=-3.5V

    Applied base bias start=0V Applied base bias end=-1V


    Output Characteristics Base current Injection start value= -1e-6A Base current Injection end value=-4e-6A Applied Collector=-3.5V
