1 tone & 2 tone simulation with spectre netlist

Hi ALL,

I'd like do the 1 tone & 2 tone simulation with spectre using HICUM
Level 0 as the BJT model.
But I don't know which controll command should be used. Is the pss
correct?

my setup is:
OP: VB=0.85V VC=1.0V
Pavs: -40dbm to 0dmb

input and output sites with DC_feed and DC_block.

My netlist is written as:

simulator lang = spectre
global 0
simulator1Options options temp=27 saveahdlvars=selected
inline subckt hicumL0V1p2 (c b e s t)
hicumL0V1p2 (c b e s t) MOD

model MOD bht0 type=NPN
+ the model parameters
ends hicumL0V1p2

parameters p1=0.85 p2=1.0 p3=1e9 p4=0.0 p5=3.162e-3 p6=0.316 p7=40
* -40dbm to 0dbm

X1 (Cint Bint 0 0 net5) hicumL0V1p2

DC_feed1 (B_DC Bint) inductor l=1uH
DC_block1 (IN Bint) capacitor c=1uF

DC_feed2 (C_DC Cint) inductor l=1uH
DC_block2 (OUT Cint) capacitor c=1uF

Load (OUT 0) resistor r=50

V1 (B_DC 0) vsource dc=p1 type=dc
V2 (C_DC 0) vsource dc=p2 type=dc

V3 (IN 0) vsource sinedc=0 freq=p3 ampl=p4 type=sine

simulator2Options options reltol=1e-3 vabstol=1e-6 iabstol=1e-15 \
scalem=1.0 scale=1.0 gmin=1e-12 rforce=1 maxnotes=5 \
maxwarns=5 digits=5 cols=80 pivrel=1e-3 ckptclock=1800 \
useprobes=yes

How to write the The controll statements here?

1. I want to bias the ampl of V3 (start=p5=3.162e-3 stop=p6=0.316
lin=p7=40), how to write it?
2. Is there power source in spectre, with which I bias the power from
-40dbm to 0dbm?
3. and how the save the output power at node OUT.


any idea?

Thanks a lot in advance!
