how to optimize the ring oscillator by hspice?

[triquent]

I simulated a 5 stage ring oscillator, and measured the propagation delay per stage. But how can I use hspice to optimize the propagation delay? To get the minimum dealy? How can I do it? use which command in Hspice?

Is it a blank link?

i also couldn't find it. Can you post it again?

If it's doesn't work agian...go to goole, type "optimizing ring oscillator using hspice" then search...

pick the one on the list titled "Calibrating Digital Behavioral Components"
