About POCV(Parametric OCV).

[srshankar]

Hii,

Please somebody share your concept of POCV(Parametric OCV).
Please share the resources or links if u have any. Regarding POCV characterization and implementation.


Thanks,
Shankar.

POCV uses a statistical approach, but it doesn’t do a full SSTA analysis. Instead, it calculates delay variation by modeling the intrinsic cell delay and load parasitics (line resistance, line capacitance, and load capacitance) to determine both the mean and “sigma” (variation) of a logic stage. The cell delay can be further broken into an n-channel component and a p-channel component. They then assume that all the cells along a path have the same mean and sigma.
