Hi
I have built digital correction logic in matlab .
How to send the H-spice result into Matlab for calculate SNDR?
THANKS
 

the hspice simulation results can be saved as a file
and then loaded into the matlab
 

after running hspice,you can get output by .lis file if using .print in your simulation file

then open .lis and delete you don't want information

save you data as .mat

in matlab command windows

load('-ascii','file name')

the file must in your current directory

then process the matrix by error cancellation logic

good luck!

ps.
sorry,i got D in English XD
 
Try the hspice command : .lprint
It is the logic print out, much more efficient for logic signals, as it only ouput digital 0 and 1.
