Hello, I'm Pangi.
I have a question whether the instantaneous current is more of a problem, or the dc(average) current is more of a problem in the electromigration problem.
I think I have seen in the pdk that the current limit for width of a wire is determined as the dc(average) current.
However, when I search the cause of electromigration, I found that the MTTF(mean time to failure) is related to the current density.
In the case of duty cycled operation, by what factor should I decide the line with?
Thank you.
