I have now come to the conclusion that the area factor parameter causes the PNP models to stop working entirely. I am not able to get any sensible results when using the previously posted pnp subckts. When using the NPN subckts I do get a working circuit but the area factor parameter is not consistent with the .model transistor behavior. I am working on the assumption that an AREA = 1 is equivalent to the .model by it's self.
For instance, the methods below do not produce the same simulation results when entering these in the model section for a device in the database manager.
.MODEL NPN1 NPN (.......)
THE BELOW SUBCKTs DO NOT GIVE THE SAME SIMULATION RESULTS AS THE .model METHOD
I assume the below methods are consistent but have not investigated this.

Hi Charkear,
What version of Multisim are you using?
