I'm a rtl engineer. I'm confused between the difference of sdf and spf back annotation. As I know sdf came from STA( PT) and SPF came from STAR-RC. So In my experiance, the sdf used to timing close the netlist without RC elements. then this netlist to send a PNR team. After extraction RC elements in layout team by starRC. Then finally we once again do post sim with spf(a.k.a back annotation) .
Is this rtl synthesis flow right ? Then where is to do CTS flow?
