On Chip Variation OCV

smachha

Hi all,

Can some one explain What is OCV ? I am confused that, 

--> applying derates is what OCV is ? or 

--> using two different libs for same (setup/hold) analysis for launch and capture is OCV ?

and What is the MMMC ?

 

Thanks,

smachha.

    Hi Scrivner,

    Thanks for the response. If OCV uses min and max libs for the for setup or hold, i believe tool is  taking these libs from the config file.

    But In MMMC, if i create a analysis view using lib

    create_lib_set -name ss0p8v120 -lib "<path>.lib" 

    which libs the tool consider for timing analysis. is it still the ones from config ? or the one i created the view with ?.

    Thanks,

    Smachha.
