Hi all,
I'm doing SSO simulation of i/o pad + pin with Tr. Lines configuration.
I feel there are 5 cases in the simulation,
----------------------------------------------------------------------------------------
Type Process IOVDD Temp Load
(F/T)
-------- (Max/Min) -------
----------------------------------------------------------------------------------------
1. VDD overshoot
2. VDD Undershoot
3. VSS Overshoot
4. VSS Undershoot
5. Delay
What I want is, how can we select corners for each case, which gives worst case
values.
For example, I thought, if L>C then its underdamped, so ringing is more, but
how to see
(which corner gives) the max overshoot/undershoot in the ringing.
My interests from the findings are
1.Ringing in Supply (VDD overshoot, VSS Undershoot)
2.Noise margin (VDD Undershoot, VSS Overshoot)
3.delay
Waiting for replies,
Canes
