Thanks Phoenixpavan!
Could you please tell how do you decide whether OCV analysis is required or not. I understand that it is more accurate as it take both min and max libs for same path. But this could be more pessimistic.
I think OCV is only require when the slow and fast conditions can be physically exist in chip at the same time. For example for if the max corner is 1v and 105C temp and min corner is 1.25v and 95C temp then OCV must be done. But if the max corner is 1.5v and 125C temp and min corner is 1.95V and -40C temp , then OCV analysis will be pessimistic, and bc_wc analysis or would be good enough for that. This kind of PVT are usually in older process like 130nm , 180nm. But one of my friend said even if the process is 180nm , you should use the OCV for accurate results. I am confuse now whether should I go for OCV or bc_wc for 180nm process :-?.
Could anybody please clear my doubts and share how do you decide the analysis type based on process / PVT.
Thanks
