Plotting problem in HSpice

hspice ac probe hertz

Hello everyone,
I'm trying to plot a capacitance in HSpice that is derived from S-parameter measurements but can't seem to do it. I know this is a newbie question as far as spice is concerned but i couldn't find a solution after a lot of scrimmaging through the manual, etc.
I'd like to plot the data in Cosmoscope after the results are outputted in the .ac file but i can't find the parameter Cin i've defined in there.
Here's the code:

.option post
R1 in 1 250e3
C1 1 2 100e-15
L1 2 3 100e-9
R2 3 out 250e3
Csub 1 4 100e-15
Rsub 4 0 250e3


P1 in 0 port=1 DC=0 AC=1u z0=50
P2 out 0 port=2 Z0=50


.param pi='355/113'
.AC dec 50 50e6 40e9
.print ac Cin = PAR('1/(Z11(i)*(2*pi*HERTZ))')

.end
Can somebody help me out please?
Ananth.

can you change .print to .probe? I'm not familiar with cosmoscope, but I don't think .print saves the data to the output file - I always use .probe...

why don't you use avanwave?

You can use .Let statement instead of .print and use with awaves
