how to plot w/r temperature, corner and supply

Hi all,

I have a question here for writting the oceanScript. I 'm trying to
write a script that can plot transient, AC and Noise with respect to
temperature, corner and supply. Basically I want to show all corner,
supply and temperature information on the plots with the written
script. Please help me out to save the simulation time.. If you have
any idea, please reply back to me.

Thx a mil..

I suggest you start ade once, and set up the simulations that you want
and set the variables and then use save to script to get an initial
ocean script. Don't care about using the corner tool, use plain ADE.

Then you divide your scripts in two: one for the simulation and one
for the plotting. Wrap your simulations in a foreach loop and set up
your corners as lists:

;; after the last desVar() setting insert the following
(setq tempL (list -40 75 125))
(setq vddL (list 3.0 3.3 3.5))
(setq cornerL (list "ss" "tt" "ff"))

(foreach (tempV vddV cornerV) tempL vddL cornerL
(desVar "vdd" vddV)
(temp tempV)
(setq modelFiles (list "path/to/wherever" cornerL)
;; Here comes your simulations .
)

This will run your simulations

Then you create a different file for the measurements and plots. Use
the same simulator, netlist and resultsdir settings as the original
script. Don't be afraid to use the awd* SKILL functions directly.
Ocean alone may not always make you happy. skartistref.pdf is your
friend on low-level graph generation, as is a couple of Andrews
scripts here.

Use load() to load the ocean scripts into your CIW session. You can
also use ocean < oceanscript.ocn on the command line, but that is
horribly slow for debugging. Running overnight is ok as long as you
don't want to do too much fancy as ocean binary doesn't load all
contexts.
