ERROR: [Place 30-126] Unroutable Placement! A BUFIO can only drive loads in the same IO bank.
hi, I met below errors:
ERROR: [Place 30-126] Unroutable Placement! A BUFIO can only drive loads in the same IO bank. The following BUFIO clock loads are placed too far from t he BUFIO to be routable. 669 u_NV_hstdm_bank_receieve_AB/pinmux_rx_bus.i_dnlvds_pinmux_rx/gen_source_synchronous_clock.i_ibufio_clk_iserdes_2x (BUFIO.O) is provisionally placed by clockplacer on BUFIO_X1Y35 (in SLR 2) 670 The loads are distributed to 1 user pblock constraints.

Here is the clock archteicture in my code.
I checked my constraints, actually below CLK_P anc CLK_IN pins are assigned to SLR3 actually.
Since the input of IBUFDS is in SLR3, I don't understand why it is reporting IBUFDS.O in SLR2 now?
