Dear all,
If I want to simulate eye diagram in hspice, how do I do?
Are there other tools simulating eye diagram?
If you have these information, can you help me?
Thanks.
 

eye diagram in hebrew

Hi,

See the Orcad's app. notes page :

Replace * by t
 

eye diagram with hspice

lots of methods
1. use cssope for waveform viewer. It has a eye function
2. print the signal in hspice and plot its eye with matlab, before this you must write a matlab script first.
3. write a pwl source in hspice netlist such as
veye aaa 0 pwl (0 0 100n 100n r)
the 100n is the eye width,
after simulation completed, open the waveform by awave
and change the x-axis to v(aaa)
then polt the signal eye

Dear flushrat,
I try (3) but I don't know 'r' means. Can you give me a example?
I simulate in hspice.

.PARAM width=1ns phase=0ns
.PROBE TRAN TIME2=par('TIME+phase-int((TIME+phase)/width)*width')
.tran 0.01n 10n

I use these. But I think these is wrong.
Can you tell me how to simulate eye diagram in hspice?
Thanks.
 

how to plot eye diagram in matlab

why don't you use MATLAB

you could move your output data to a matrix and import it to MATLAB, with a few lines of programming you could plot the eye diagram

excuse me sir
could you tell me more about a "few lines of programming you could plot the eye diagram"

thank you
 

eye diagram hspice

hi
use hspice toolbox.
 

Re: Eye diagram

Hi,

In the calculator option of most of the tools I've found Eyediagram plotting option on which it will be plotted..I've found them in Cadence Virtuoso Analog Design environment and Mentor Graphics - System vision.

Eye diagram

does hspice toolbox need additional license?

hi! sir

could you give me a sample program regarding eye diagram?
thank you sir..
