[SI-LIST] Re: Statistical Timing Budgets Analysis

You could, depends whether the spice model
Is set up to model the statistical variability of AC timing.=20
 =20
Best results will be to measure split lot devices.
And construct your own probability density function.
The IC vendor should have such data.

Subject: [SI-LIST] Statistical Timing Budgets Analysis

Dear all
    Now I do some  statistical timing budgets analysis abuout tight
timing interconnect.I can model the physical parameters on the=20

PCB,such as :trace,voltage noise,via.But,I couldn't find  the
probability density function between devices AC time parametera and PVT
(Process Voltage TEMP).

How to obtain it? Just simulated by a spice model?


Best Regards.
