Hi Kicha,

Go through the below link.

Alpesh Kothari: Temperature Inversion. Is this a new 45nm effect?

Arjun,

Thanks for the reply.

I have already gone thru' this doc, but it gives the description of Temp Inversion and how it is applied.
I want to know what is the cause for it, in sense why it is seen in 65nm and below but not above 65nm.

What factors impact the delay in temp Inv corner ??
