Hi,

Has anyone done simulations using the .age command in ELDO, to estimate the effect of NBTI on pmos transistors?

I am trying to make this work, but the problem is that I get the same results wheter I simulate with an age of 1 year, 30 years, 100 years and so on...

Does anybody know what might be the problem?

Where did you get the aging parameters from?

Hi,

The aging parameters came along with the designkit we are using. The designkit is 90nm from CMP, but the only library I found containing aging parameters were something called NBTI.lib.
I suspect that the .age function doesnt get all the right parameters from this design kit.
