Hello everyone. I am trying to find the values of a specific iteration (or all of the iteration) of a monte carlo simulation run of 1000 samples.

In HSPICE I did this with a variation block where the 3-sigma value corresponds to the Fast or Slow corner.

Code: 
.Variation
	.Global_Variation
		Parameter Toxvar = N()

		$Distribution for 1.8-V NMOS
		NMOS NCH tox=Perturb('(0.133e-9/3)*Toxvar')
		NMOS NCH vth0='0.1/3'
		NMOS NCH xl='0.133e-9/3'
		NMOS NCH xW='0.22e-9/3'

		$Distribution for 1.8-V PMOS
		PMOS PCH tox=Perturb('(0.133e-9/3)*Toxvar')
		PMOS PCH vth0='0.067/3'
		PMOS PCH xl='0.133e-9/3'
		PMOS PCH xW='0.22e-9/3'
	.End_Global_Variation

	.Local_Variation
	$No Statistical data for mismatch considerations
	.End_Local_Variation
.End_Variation

.dc temp -25 100 5 monte=1000

I'd like to get the values of Vth, tox, xl, and xw of each iteration run. The manual states that I can aquire this through CScope but the license only allows me to use Avanwaves. I'm using HSPICE ver:A-2008.03. How should I get them? Thanks.
 

have you tried plotting/exporting the values by yourself? I mean, no one would use the GUI for acquiring the values, there must be a way to automate/script it.
 

I was interested in a command statement. like a .measure and see the parameters on the LIS file.

though I did see the values (I believe) in the .mca0 file. Am I correct in saying that the parameters I am looking for are in the .mca0 file?

Code: 
index	toxvar@IGN	nch@vth0@IGN	nch@xl@IGN
nch@xw@IGN	pch@vth0@IGN	pch@xl@IGN	
pch@xw@IGN	nch3@vth0@IGN	nch3@xl@IGN

The values listed is (I believe) the ones used from iterations 1-3.
I'm gonna say this now. It will be a pain sorting these out in excel (LOL)

I have a follow up question.
What does IGN and MGA stand for and what are their implications in my simulation?
 

UPDATE:

Turns out that IGN and MGA refers to (Independent-Global-Normal) and (Model-Global-Absolute) respectively.
Now that I have found these values. I've been looking at the HSPICE manual and it's a bit confusing to manipulate the .lib file.

Code: 
. LIB TT
.param
+toxn   = 4.08E-09        toxp   = 4.08E-09       
+dvthn  = 0               dvthp  = 0              
+dxl    = 0               dxw    = 0              
+cjn    = 0.001000266     cjp    = 0.001121       
+cjswn  = 2.040547E-10    cjswp  = 2.481E-10      
+cjswgn = 3.340547E-10    cjswgp = 4.221E-10      
+cgon   = 3.665E-10       cgop   = 3.28E-10      
+hdifn  = 2E-07           hdifp  = 2E-07          
.lib 'mm018.l' MOS
.ENDL TT

Here are the parameters for the Library. Is there a way to manipulate these values from the netlist like say for example the Vth0 for NMOS in the 3rd iteration in monte carlo is -0.03376 and write a code that substitutes this in the library like say .param dvthn=-0.03376?
