How many types of noise can we calculate using hspice?
I am focussing on cmos inverter circuit.
I have pre and post(with RC components) circuit file ,a testbench, model file.
Noise data is getting published in the output lis file.
I am not able to figure out actual noise calculated as there are so many thing getting dumped in lis output file .
I am not working on any tool,only commands on linux .
Can anyone suggest calculation of noise of inverter using hspice?

What do you want to mean ?

I mean which type of analysis : transient analysis,AC analysis or DC analysis and noises like: flicker,shot

Use ".noise".
Used this .my code is below:
.PROBE V(ZN) V(A1)
.PROBE V(ZN) V(A2)
.AC lin 1000 1HZ 1GHZ
.NOISE v(ZN) VA1 VA2 1000
.PRINT ONOISE INOISE

output file generated with this code is *.lis
it has lot of data about what models we have used,values of technology parameters ands noise data also.
Question is how can i verify that the noise is coming though analysis is the correct one.?
Liberty file does not have noise data on which i am working .
 


It can not be true.
Show me true netlist.

".PRINT ONOISE INOISE ".
Done this.

What do you want to mean ?
Use correct terminology.
I am using correct methodology.using nangate libraries of 45nm technology .These don't have noise data.

Sorry that was misprinted, Liberty does not have noise data or noise is written with some other identifier in the liberty which i am not able to figure out.
I have seen noise data in ccs liberty files but not in nldm.
Does noise can be calculated for nldm or ccs only. ?
 

i am taking noise data in liberty files as reference for my calculation results using simulator hspice.
I am trying to calculate noise with nldm method using hspice.
