assura to diva
My opinion is, sometimes DIVA is not accurate. I used Dracula instead
of DIVA. I tried both of them and sometimes Dracula gave me some
errors when DIVA pass my design. DIVA is easy to use cuz it's online
check, click this, click that, and you are done. Dracula checks your
design offline. Not as easy to learn as DIVA, not as easy to use as
DIVA, but performs way better.
Nowaday, best way for analog circuit verification is Dracula plus Calibre,
I suppose.
