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 _?_ _?_ _?_
