bjt spectre netlist

Hello everybody,

I want to instantiate a pnp BJT in CMOS technology through Cadence GUI. We got the symbol in design library. But I always met errors. So I turned to add pnp transistor in Spectre netlist file. Since I am new with pnp BJT in its properties, such as "device area" etc, I don't know how to instantiate it in netlist file. The model file for pnp is shown below. I have tried several times with errors.

Can someone give me a hand for this? Appreciate your help.

The properties in schematic window for this pnp transistor symbol by default show below:

Model name: PDIO (--I doubt here that why it lists "PDIO", not "pnp10". I have replaced it with pnp10, it turned out error)
Bulk node Connection: vdd
device area: ?
Multiplier:
Temp rise from ambient: ?
Estimated operating region: fwd

So, for netlist file, how should I do? for example:

Q0 pnp10 _?_ _?_ _?_

spectre pnp model

Did you just try specifying the model name as pnp10 in the symbol form and then include the model file in the analog environment, which has that pnp BJT model text which you pasted. Then it should run fine.
