1.Warning: No clock-gating check is inferred for clock clk_d (其中clk_d是通过clk generate出来的)
2,Warning: The drive-resistance for the timing arc
(scadv10_cln65gp_rvt_ff_1p1v_0c/BUFHX16MA10TR) clk_rx__L1_I0/A-->Y (min rising & falling positive_unate)
is much less than the network impedance to ground;
PrimeTime has adjusted the drive-resistance to improve accuracy.
