save DC oppoint in spectre
Jul 03rd, 2008, 4:42am
 
Hi

the spectre command : save <instance_name>:oppoint does not work for me. (like save M0:oppoint), I got the following error message:
'M0': Does not have a terminal named 'oppoint'

Do you have any idea what can be the problem?

I want to save DC operating point data during DC sweep...

Thanks,

I thought you were supposed to do something like

op1 dc oppoint=screen

Actually I want to run DC sweep simulation (like vary the drain voltage or gate voltage) and i want to plot some values of the operating points (like gm, Cgg...). So, I do not want only one value, rather a function ...
similar thing as the method known as gm/Id

?
