i want to simulate a circuit in hspice with TSMC 180nm process.
in this ciruit there is a vertical substrate PNP transistor.
how i can present this transistor in netlist of hspice?
tnx

Either get the model from TSMC or via an institution like MOSIS (registration and/or NDA necessary), or use a generic (h)spice model, which of course cannot be very precise for the particular process.
 

tnx for you help
But I mean how i write the netlist?
Is it correct to write like an ordinary bjt transistor?
Like: Q(name) NC NB NE Model <AREA>
Or it might be different?
if it is different, how I must write?
 

It will probably just be a standard PNP model, maybe with a substrate connection (which is optional on the standard PNP model). It could be wrapped in a sub-circuit. The only way to find out is to look at the Hspice model.

Below pls. find a 0.18µm TSMC Spice model file from the public domain, which includes each 3 PNP's for 1.8V and 3.3V, together with corner variation data. If you know HSpice, you'll know what has to be changed in the syntax (if any).

Directly use one of the (different area) PNPs which would fit for your application:
Q(name) NC NB NE Model
