Hi all,

Is there any way to make cadence virtuoso layout faster when using SHIFT + F on large layout ?
Once I open CHIP level layout, and press SHIFT + F to make everything visible, it takes lot of time to make everything visible because of large layout.
Is there any way we can make it faster ? I have used calibredrv , it is way faster. Can we do that in Virtuoso ?

Thanks
Sam
 

Re: SHIFT + F option in cadence virtuoso layout takes lot of time

From what I know (I am in no way an expert in Virtuoso), Virtuoso layout editor is very slow on large layouts.
Virtuoso is not designed and is not supposed to be used for that kind of tasks.
Even calibredrv may be slow, on large SOC full chip type designs.

I found that klayout (www.klayout.de - a free open-source super high quality layout editor / viewer) is way faster than any of those industry standard tools.

Why do you want to view / edit full chip in Virtuoso?
