Could anyone explain about Sensitivity in SSTA

[evesjh77]

Hi.

Now I'm studying SSTA and I have question about that.
In the SSTA, Delay is :
Delay = Delay(nominal) + a1 + a2 + a3 ...
I can understand Delay(nominal).
But I can't understand "a1,a2,a3.." that called "sensitivity".
Could anyone explain about that detailedly?

Thank you.

never heard of that term. where did you get that from?

Sensitivity is a change of design characteristic (delay in this case) in response to a small change of some design parameters - such as device characteristics, parasitic elements, temperature, etc.
The absolute change (normalized by the absolute value of the change of design parameter) is called absolute sensitivity, the relative change normalized by the relative change of design parameter is called relative sensitivity.
