When I look at a timing report with setup in a reg-to-reg path, I look for
1. Startpoint and endpoint clk names and triggering edges.
2. Network delay & skew between the two clocks.
If the skew is large, then the clock tree is not properly synthesized or the clocks are not grouped.
3. Combinational delay.
If there is a weak cell in the datapath, increase its drive strength or add buffers.
Correct me if I am wrong and share your views.
thanks,
