Hello,

Are you doing Pre-layout or Post layout STA? If Pre-layout, have you set the wire load model?
Can you please post script for same? So we can better understand that which constraints you given? Because constraints is major part for STA.

Regards,
Maulin
 

I suppose you have used functional libraries instead of timing libraries. Functional libraries do not have any delay for the cells.
