1) Suppose we have a PVT corner with 1.3/1.08/130 . what does that number 1.3 really denote.
2) Also can this happen that 2 scenarios in the design whose PVT corner numbers differ only by Process.
Like sc1 = 1.3/1.08/130 and sc2= 0.7/1.08/130.
Thanks
 

1.3 is your P(process or doping concentration), 1.08 for your voltage and 130 for your Temperature. That's how it is named generally.
Yes, When taking the corners we can have variation for any of the PVT conditions because of the fact that your doping concentration can reduce or increase the speed of your device, leakage and the power parameters.

Thanks so much. Doping concentration was wat i was looking for.



What would be the unit for Process(doping concentration) ?? or is it 1.3 times something?
 

Process variation is due to unpredictability of fab process. So 1.3 means, 1.3 times the normal concentration .
